How this service works
Chemical properties for a compound by name from the NIH PubChem service, no key. Returns molecular formula, molecular weight, and IUPAC name. For AI agents in chemistry, drug discovery, and materials research.
Output
Returns a JSON object containing the molecular formula (e.g. C8H10N4O2), molecular weight (e.g. 194.19 g/mol), and IUPAC name (e.g. 1,3,7-trimethylpurine-2,6-dione) for the queried compound as sourced from NIH PubChem.
Example use cases
Drug discovery compound identification
“What is the molecular formula, molecular weight, and IUPAC name for ibuprofen? I'm building a database of common NSAIDs.”
Chemistry homework compound lookup
“Can you look up the chemical properties of ethanol for me — specifically its molecular formula, molecular weight, and official IUPAC name?”
Materials research property retrieval
“I need the PubChem data for titanium dioxide — give me its molecular formula, molecular weight, and IUPAC name.”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-pubchem-compoundWhen to prefer
Use this endpoint when you need quick, no-API-key access to basic chemical properties (molecular formula, molecular weight, IUPAC name) from the authoritative NIH PubChem database, especially in agentic pipelines where obtaining a PubChem API key is impractical. Prefer this over direct PubChem API calls when operating in a pay-per-use x402 payment context.
Side effects
- Compound name not recognized by PubChem — returns empty or error response
- Ambiguous compound name matching multiple PubChem entries — may return first match or fail
- NIH PubChem upstream service unavailable — proxy returns 5xx error
- Malformed request body — returns 400 bad request
- Payment not received — returns 402 payment required
