Dear friends, If you would like to add an API to our database, please submit your list to mail@api-data.com. The data will stay forever in our database and will be fully searchable for all our visitors. We only charge you $300 for this. This one-time fee covers adding your list of substances, CAS checking, chemical formulas and creating a page with your company’s details. We hope for your understanding here. We know we used to add substances for free, but we’re facing a growing number of requests here and are no longer able to process them like before. Thank you for your interest and have a great day.
