Build on governed product data
Use one typed REST and MCP contract to explore the Hyran entity graph, compare BOM yield history, and create bounded exports. Credentials remain organization-bound and PostgreSQL forced RLS enforces the final tenant boundary.
What the API exposes
Entity graph
Search styles, SKUs, materials, suppliers, and immutable BOM publications.
Historical BOM yields
Compare completed snapshots with stable temporal and provenance semantics.
Governed exports
Create asynchronous CSV exports without exposing SQL or direct database access.
Authenticate safely
Ask an authorized Hyran operator for a scoped API credential. Send it only in the Authorization header over HTTPS.
Read authentication guideUse generated contracts
OpenAPI 3.1 is canonical. Import it into Postman or generate a client without copying endpoint definitions.
