How to call it

POST https://quantum-artificer.surewhynot.app/v1/chemistry/compute

Each call costs $0.005 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://quantum-artificer.surewhynot.app/v1/chemistry/compute

Parameters

ParameterTypeRequiredDescription
operationstringYesOperation within this domain. One of: thermo_properties, equilibrium, adiabatic_flame_temp, ignition_delay, reactor_sim, flame_speed, fluid_properties.
specobjectYesOperation-specific structured problem definition — see /v1/capabilities for the exact shape per operation.

Example response

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.
