Changelog

Notable changes to the ARCNM API, SDKs, and developer platform. The API reference is auto-generated from the OpenAPI spec, so it always reflects the live API; this page records the changes behind it.

The public OpenAPI spec at /api/v1/openapi-public.json is the machine-readable source of truth — any change to the API surface appears there first.

Added — Public developer portal at arcnm.io/docs: quickstart, authentication, concepts, recipes, SDKs, and a full API reference.

Added — The API reference is now auto-generated from the public OpenAPI spec on every build, so it can never drift from the running API. Each endpoint ships request/response schemas, enum values, multi-language samples (cURL / Python / TypeScript), and example responses.

Added — Machine-readable docs for AI tooling: llms.txt, llms-full.txt, per-page Markdown, and an interactive API explorer.

Changed — Every public endpoint now declares a typed response model, so the generated schemas are complete.
