I'll also add a kind of "filter", so let's say when you write "Sodium" it might also show SODIUM hydroxide or SODIUM carbonate right now, I'll have to
add some kind of system so it automatically only shows the element SODIUM.
I'll make it freely available for everyone! ( if I didn't already mention that eariler in the thread. ) Plus I'll probably also make the source code
public, so if anybody wants to make a tweak they can do it.

Hi my friend.
I already replied your post asking for price of reagents but I think you've a very, very hard job on your hands. prices changes like Dollar and EUROs
quotation changes. They can change everyday and every time. Like some actors here in this Blog already have said it's important to know which country
do you want to deliver the goods cause the Customs specifications that's different country by country. It will be a difficult job to create something
like you're wiching for, but I'm really wish you a good luck!

Thank you!
I mean, SciFinder already has done this. What I am really trying to do is just make a "SciFinder" for suppliers that sell to private individuals, and
is completely free. But I will do my best to include shipping costs etc.

Right now I am working on adding suppliers in the U.S.
I am using this forums list of suppliers, but I do not know which ones you guys prefer.
Right now I have added Carolina Chemical, Science Company and Elemental Scientific. Which ones do you all think I should add next?

Well, Elemental Scientific is shutting down and clearing house, so you might actually have to remove them.
If you are willing to include suppliers that are not officially chemical suppliers but sell a good variety of chemicals, Duda Diesel and Seattle Pottery Supply are among the most popular.
As far as actual chemical suppliers go, Ambeed has basically everything, but while they will allow you to purchase with a personal credit card, I’m not sure if they ship to residential
addresses. The only time I ordered stuff for myself from them, I had it shipped to my university address just in case. So someone else will have to
confirm if they truly ship to individuals. Same goes for Oakwood Chemical, Combi-Blocks, and aablocks.

Ah, didn't know that - will remove Elemental Scientific now then.. It was actually so difficult to add Elemental Scientific :/
And yes, I can definitely still add Duda Diesel and Seattle Pottery Supply. I geuss amateur chemistry is all about getting chemicals from accessable
sources, so it makes sense to add them.
I am pretty sure Ambeed ships to residental addresses, so I'll add them too.
Thanks for the list!

I have compiled a list of potential suppliers in the US. Keep in mind that I have not purchased anything from these sites, and so may need some
vetting before adding them to your software. I tried to exclude sites already listed on this site. Also, I have not verified that all of these, sell
to residential addresses.
Some of these I think will be a good addition. There is one that specifically sells solvents and other chemicals relatively cheaply, and for amateur
purposes. There is also another site I found that sells polymer precursors. I hope it helps!

I have ordered many things over the years from McMaster-Carr as an individual. The shipping method is fast but pricey. The website is simply www.mcmaster.com

https://www-live.chemdirect.com/
Again, they need checked because I haven't ordered from these.

The list says Carolina Chemical doesn’t exist anymore, but their website still works for me. Carolina Biological is an entirely different company.

As I am soon done polishing the european version, if anybody want's to be a tester for my software, I'd appreciate it!
I'll still need to fix a few things.

It was a bit more dififcult to do in javascript, so I decided to do it in python. When I am done, I can always just do it in JS afterwards too.
Anyway, this is how it's looking in a console app so far. I am still adding the shipping, quantity, notes, etc.

I still need some beta-testers, if anybody is interested? I am still not done for the beta-version yet, so it's going to take a while still.
Also, it is a bit more difficult for elements. For example if you search "sodium", the top results are sodium chloride, etc, but I'll get to fixing
that.

Couple of questions,
- You said this will limit the scope to suppliers that sell to individuals. How about for specific products? eg: Carolina Chemical sells to
individuals, even 1L of H2SO4. But if you try to buy the 2.5L (or larger) bottles of H2SO4 then they require that you be a school or run a business
(and ship to those addresses)
- How does this pull the prices? Did you go to each individual supplier and see if the frontend sends requests to a backend API, then use those? Does
it just scrape the HTML for simpler websites? I'm hoping you have some simple modular system that allows for small changes (eg: if the paths or ID's
of the elements change, they use pagination, etc).
- Do the results get cached for any amount of time? eg: If the same SKU or CAS gets pulled up in different search results, it might not make sense to
query/parse the same web page/product multiple times within 24 hours).
- Is this going to be open source?
Hopefully you're structuring it so that there's just some logic module that does the data, then that can be used in either a CLI client (like what
you're showing) or use something like FastAPI to create a basic web client.
I'm a software engineer, I do NodeJS for my professional job but I do a bunch of Python on the side (mostly for 3D printing related, eg: moonraker),
and I'd love to see the code for this :-) (show me yours, ill show you mine).

Of course! I love you alls questions and feedback!
1: I have not checked the website for Carolina Chemical, but for some of the european ones there will be a little popup saying that it is not sold to
private individuals above a certain concentration or amount. My python script could potentially check for that.
2: This was very difficult to get to work, so the way it works right now is like this: It uses the search link, for example: "example.com/search=" +
the chemName. Then it uses beautifulsoup to extract the HTML, where it finds the product and price from their classname. As you noted, this can be
quite unreliable - so I am definitely also considering possibly doing a daily check for each of the websites in the sitemap.xml (since it'll take too
long to do for each individual search), whereafter it'll find the product name and price - possibly by finding the first currency-symbol and then the
closest chemName to the price-element. Of course chemical names differ, so it'll run through the Pubchem API for all of the synonyms.
3: That's kind of what I considered too (like I said in 2) - but so far it only checks for individual searches. There is not database, yet. I also
thought that if I was to do this, I would do it as one of the last things, since making it extract the price and chemical name is the most important
thing.
4: Yes, of course! Besides, if the chemical suppliers websites whole system and URLs change, I would much prefer if it could be fixed by others than
me. Also, I am just a amateur chemist and amateur programmer, it would be very ineffecient and ignorant to only let me edit it and understand how it
works.
Yes I am structuring it like that.
Oh, maybe you can help me with some of it then - I will definitely need help at some point.. probably more than just one point. If you would
like to help me with whereever I need help, I'd really appreciate it.
Yes - I'll show you the code. It's structured quite poorly now - with variables that are.. well.. badly named. I'll fix it and send it to you in just
a bit. Where (and how) would you prefer me sending it to you?
EDIT: I would loved to have used the suppliers APIs, I really would - but most of the suppliers never replied back to me after I told them I would
like an API. There was one that replied back saying they'll send my message to their "tech-team", after which they could send me the API. It's been
three months, they have no intentions on doing that.

Carolina Chem is an easy one for this, it always just says "This item is sold and shipped to schools and businesses only.".

I've had to automate stuff like that. It's... even less fun than it sounds, lol.
A lot of these websites keep the chemical synonyms paired with the listing, so typically searching for any of them should return the same product (at
least on a few that I tried).

Well, sir, since it would be a client side API (if its used on their website), just keep an eye on your networking tab of your browser.
Example of how to do it with LigmaAldrich
1) ProductSearch query:

gets a response with unique product keys:

2) Using the unique productKeys, request the Pricing and Availability endpoint:

Which will give you the price:

I think this would almost have to be done for some of them that populate the UI using RESTful calls from the client side. Otherwise, whats the best
option? Launch a headless browser to track the client side requests? Way more tedious.

|
I guess this comes down to if you want it to be a stand alone client, or a service you provide? (Or either?) If its a service you provide, I would
have it cache the prices only on the first time its requested, and have a TTL for the prices that can expire, and only then will new requests for that
item trigger actual price updates.
If its a stand alone client, then I would do the same thing, but store it in a sqlite database.

Excellent! Open source is the way to go.
This is something you really need to put some time into and think about. It looks like you're just developing a Proof Of Concept right now,
so its not a huge deal, but when you work on the first release this is something that is key. Every website operates differently, but you want the
same data. So I would create it in a way that each site has its own module that just takes an input, then it can go about getting the data (cache,
RESTful API search, HTTP requests and parsing data, etc), then return a simple object with the results. Obviously each one should be in its own file,
making it super easy to replace/update them when needed.

That's a bad sign, though I'm guilty of it as well. If you're doing this in Python I would highly recommend putting a hold on your coding and read
through the PEP8 style guide first. It seems silly, but coding in a specific style will save you headaches later on. And its just more professional, so you
should get use to it ;-)

Then throw this baby up on Github, I'd love to take a look at it :-) I do a lot of programming for work, so I rarely dive into more programming on the
side, but this might be a good way to contribute to the amateur chemistry community that has helped me so much.

Here's an example of how to use Chemsavers API endpoints.
Sending the query for toluene:

And you get back a pretty beefy response with all the related products, and their prices:

But how do you do it programmatically?
Grab the curl request command for that specific request:

Throw that in your console, add some jq to make it pretty and get the data you want:

Do you need it in a different language? Python you said? Use CurlConverter.com for that:

The same process would work for AmBeed:

Obviously it might be better to search by CAS for Ambeed, or you could just look through the results to make sure they're what you expect. I searched
for "toluene" and got a lot of results, none of which were actually toluene.
Elementalscientific has something that you can query, it returns the price as HTML, but that makes parsing it a heck of a lot easier:

Before you go through and do all the work on the search code for your tool, I would say go through to each chemical supplier and see if they have a
public facing API when you search on their website. Create a list of which ones do have API's, which don't, and which ones are a hybrid (some have an
API for searches, then you'd need to parse the HTML for the price - example: Carolina Chemical).

Thank you SuperOxide!
I am still a bit confused with exactly what to do, but I have been researching it a bit, and I am still a bit confused .. but it helped!
There is this european website I want to include: https://www.laboratoriumdiscounter.nl/en/
I am having a hard time finding their public facing API. Maybe they do not have one? What do we do with those?
Thank you for your help! I really appreciate it!

Which part are you confused about?
Some of the simper websites are just basic HTML (eg: DudaDiesel). Those you would pretty much need to just curl the endpoint that the search goes to,
then parse the output for prices. Not really any easier way to do it.
Then some of the other, more advanced websites have public facing API endpoints that are used to make the website quicker. Since they're public
facing, you should be able to query it.
For some, you may need to send a simple cURL request to the main website and look at the return headers for a cookie or some session key, and use that
value in the subsequent API calls. But that's not super difficult. And not all of them require that.
It looks like they do have an API, and probably the easiest one I've seen so far, lol.
Here's how to tell: https://imgur.com/hjLzxrd
And I had to break the video up in two since imgur limits it to 1 minute. Heres the end of that where I show how easy it is to change the product
you're querying for: https://imgur.com/ZMkHcFw
P.S. In the videos I shared, you can tell im using a Macbook. So you might not have the same functionality I do on the command line. But still, it was
just to show you how it can be done.
P.S.S. Here's some very crude python to grab the cheapest price for whatever the search string is:
Attachment: php8vYt1p (18kB) This file has been downloaded 20 times
Obviously you would want some logic that would make sure the result item you're analyzing is actually what you searched for. You can see I searched
for benzene and it returned (1-Bromoethyl)benzene >95.0%(GC) 25g. But if I searched for the CAS of Acetone, it returned
acetone.

Thank you! Now I understand! :-)
Yes I get what you mean, their websites search function is not very nice for IUPAC names. I think we will do CAS-numbers instead, then.
So for the rest of them, that don't have an API (the smaller ones), do we just do my initial approach with them? .. which was using BeautifulSoup to
get the HTML, and use the classes to find the price and product?

Yeah, the thing is that people are probably going to want to search for names too. And what if not all websites allow you to search by CAS?
What I would do is allow someone to type in a CAS or chemical name, then you query Pubchem to get a list of chemicals with that name in the
title (obviously putting exact matches at the top of the list, since they're most likely the correct one), and allow the user to select the chemical
from that list. That way you know the exact name and CAS number, allowing you to search for either (or both, if applicable). This would be a
property you would include in the module for each vendor (eg: allowsCasSearch) to see if you can just jump right to the CAS search instead of
Name search that you then need to verify the CAS for on each (if possible).
I think this is a good approach, because if someone searches for a chemical with the name Supercalifragilisticexpialidocious, you don't
really want to query every website for that name if you're fairly certain it doesn't even exist, right? Just a thought :-)
Quote: Originally posted by Maui3  | So for the rest of them, that don't have an API (the smaller ones), do we just do my initial approach with them? .. which was using BeautifulSoup to

Yes, unfortunately. And that's the tedious part.
Lets look at DudaDiesel as an example. Querying for products is very easy, just need to cURL their seach.php page with the query parameter.
If I wanted to search for acetone, I would query the URL: https://www.dudadiesel.com/search.php?query=acetone.
That would return a plain HTML page, no fancy AJAX queries to get the prices - they're all on that page.
But then parsing the page to get the prices is a bit of a nightmare:
- The prices themselves don't start with a currency sign.
- There are input fields for quantities, which do contain the prices in hidden inputs, but not all items have those. The freight items
don't, for example.
- The HTML nodes with the prices don't have any unique identifiers or classes that you can directly search for, neither do their parent elements,
or their parent elements, etc.

- The only way I can think of to get the price values from this mess, is to look for div.item_spec HTML elements that contain strings
"QTY" and/or "$Ea.", then grab the next sibling div.item_spec that has a float value in double quotes - and assume that's the price.
- Alternatively, since all of the price elements seem to be formatted like <b>1+</b><br />8.48, you could look for any
div.item_spec elements that have content that matches the RegExp pattern <b>([1-9]+)\+<\/b><br
\/>([1-9]+\.[1-9]+), which would give you the quantity and the prices (example of pattern).
- Regardless of which of the above two parsing options you choose, you would need to narrow down each one to the specific <table>
or <tbody> node for each individual product listing.
As you can probably guess, the above searching can be pretty tedious. And it would be even worse if the prices aren't listed on the search results
page, so you would need to parse the search results page for links to the products, then cURL each of those pages and run similar logic to get the
prices.
This gives me a headache even thinking about it, lol.
While I have't used Pythons BeautifulSoup before, it does look like it would be able to take care of this.
Do you have a list of websites you want to include? Post them here. Maybe I can help with a quick analysis of each.
And do you know much OOP? I think the best way to handle this would be to create an inheritable class that has the main common methods that would be
used for any of the merchant websites (simple cURL functions, JSON parser functions, HTML parser functions, etc), then each website you want to query
would have its own class that inherits the base class, and is in its own file that would be included/imported and used to query for prices on that
website.
I have an example of that type of setup in a recent project I was working on. I created a Moonraker plugin module called moonraker-contrast which needs to be able to parse gcode files from different slicers, so each slicer has its own module file, which contains a class for that specific slicer type (each of which inherits from a generic slicer class that has the common methods), and each slicer module is included in the main contrast.py file.
This means if I need to change the logic for one slicer (or in your case, chemical supplier website), I can just modify that one file. And if anyone
wants to add a new supplier to the search feature, they just need to create a new module/class that inherits the base class, and put it in the right
directory.
But, first things first. Do you use Git (revision control)? If not, start using it. Sign up on Github.com (free), create a repository for this
project, then install git on your local machine and commit some code to it. Start checking in your changes so you don't lose any of your files or
anything.
- Install git
- Create a repo and add some code to it
Sorry if this is a lot of information for you to take in. I think this is an excellent learning opportunity for you though, and the project as a whole
sounds like an excellent idea.

This sounds like a great idea!
I will start working on all of this (setting up github, coding, listing website, etc.)!
For the list of websites, I can list the european ones, as I am from Europe. I do not know enough about where to buy in North America (or other
places) to make a list for that. But this page could be helpful for that: https://www.sciencemadness.org/smwiki/index.php/Lab_supplier...
For the european ones, this is what I've got:
Laboratoriumdiscounter
Pretty much everything (at a quite cheap price too) an amateur chemist needs for most projects.
S3 Chemicals
A lot of standard and also a few somewhat obscure reagents at really good prices.
Onyxmet
Has a lot of elements and obscure reagents that are otherwise hard to get for amatuers like NaBH4, etc. Not a lot of chemicals though.
Laborladen
Does really not have a lot of chemicals, but very cheap metals.
Warchem
Has a lot of reagents, which are also available in smaller quantities. Is also really cheap. Though they only sell to poland.
Possibly Lerochem
Has really cheap common chemicals.
.. but I need to hear some other reviews for the place first.
Hadron Scientific
Has really cheap common chemicals, and a few obscure ones.
There are more, but I feel this is the best to start with anyway.

What luck, none of the ones you sent me had API's, lol. But heres a quick analysis of each, and how I would go about doing it. Some of them simply
keep the price in a <meta> tag, which makes getting it very easy.
- Laboratoriumdiscounter: [Easy] - Just get to the right product page, then look for a meta tag with the property og:price:amount, and
grab the content of that tag.
- Onyxmet: [Easy] - The product pages have the price is in its own <h3> tag with the class product-price.
- Laborladen: [Medium] - Pretty messy price formatting. No easy ID's or classes that only apply to the prices.
- Warchem: [Easy] - There are a few ways to get the price from here. On the products page, it's stored in a meta tag (similar to
Laboratoriumdiscounter) with the property name product:price:amount; several <input> elements with the IDs parametry
and InputCenaKoncowaBrutto, as well as a few other places (some JS variables).
- Lerochem: [Easy] - The product pages have the price in a <div> tag with the class current-price
- HadronScientific: [Medium] - Search kinda sucks, and the price is in a badly formed HTML table. But it looks like the price is stored in the
element with the .column-3 class name (from the product pages I looked at). This might make it easier.

All the sites I listed earlier in the thread are based in the US. The SM wiki lists some others as well.
You're doing an excellent job, by the way. It looks like the software is coming together!

Sites may change from time to time, the code changing along with them. I recommend you inspect them occasionally to make sure your code is not
outputting something else. Color codes, for example, or gibberish.
