GET /t/chem/compatibility

unprobed

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.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
