How this service works
Can chemical A be safely mixed or stored with chemical B? Pass two CAS numbers or names. Returns a verdict (incompatible / caution / no_known_hazard), the reason, expected effects (gas evolution, heat, fire, toxic fumes) and confidence, from expert reasoning over PubChem GHS data and CAMEO-derived reactivity profiles. JSON response. $0.03 USDC per call, pay via x402, no API key.
Output
Returns a JSON object with the resolved names of both chemicals, a verdict ('compatible' or 'incompatible'), a plain-language reason explaining the interaction, a confidence score between 0 and 1, and a list of expected effects such as 'toxic fumes' or 'exothermic reaction'.
Example use cases
Lab reagent storage safety check
“I need to store hydrochloric acid and sodium hydroxide in the same cabinet — are they compatible, and what should I watch out for?”
Cleaning product accident prevention
“Someone mixed bleach with rubbing alcohol in a bucket — are those compatible chemicals or could that be dangerous?”
Industrial process compatibility audit
“Before we combine acetone and hydrogen peroxide in our manufacturing line, can you check if those two chemicals are compatible and tell me the confidence level?”
Technical details
Endpoint
GEThttps://toolsmith-api.dassad10.workers.dev/t/chem/compatibilityWhen to prefer
Choose this endpoint when you need a quick, automated chemical compatibility check without setting up accounts or API keys — ideal for AI agents performing safety screening, lab workflows, industrial process validation, or compliance checks. Prefer this over general chemical databases when you need a binary verdict plus confidence score in a single call, paid per-use with USDC on Base.
Side effects
- Unrecognized chemical name or CAS number returns an error or low-confidence result
- Ambiguous chemical name with multiple matches may reduce accuracy
- Very obscure or novel chemicals may lack training data, yielding low confidence
- Missing required query parameters a or b returns a 400-level error
- Network or worker timeout on the Cloudflare edge returns a 5xx error
