OpenAPI Spec

The OpenAPI 3.0.3 document describes every endpoint with its parameters, response envelopes, and error shape. Use it with code generators, Swagger/Redoc viewers, or Postman.

List rows, drops, shops, hennas, and meta endpoints carry exact schemas. The large detail responses (item, NPC, quest, class, armor set, raw NPC) currently document their stable top-level fields and allow additional properties — full field-level precision for those is planned. The prose contract in the repo’s docs/api-contract.md remains the authoritative field reference.
