What the API Provides

Deterministic endpoints for the standard.

API calls return the same fields produced by the Python package: typed notation, Exergy Factor, accessible exergy, Fidelity Tier, basis, boundary, and conformance information.

POST /v1/calc/thermal
GET  /v1/registry
GET  /v1/tiers
POST /v1/validate
POST /v1/compare

The free key is intended for testing, prototypes, research, and early integrations. Commercial or high-volume use can move to a supported plan later.
