# Quicknode API versioning

This page maps the version identifiers used by HTTP APIs that agents discover from quicknode.com. Product documentation and OpenAPI descriptions remain authoritative for compatibility and deprecation details.

## Surfaces

- **Agent API (this host):** OpenAPI at https://www.quicknode.com/openapi.json. Current paths use the `/api/v1/` prefix.
- **Admin API:** OpenAPI at https://www.quicknode.com/api-docs/v0/swagger.json. Production requests use the `api.quicknode.com` host and the `/v0/...` path.
- **Streams, Webhooks, KV Store:** OpenAPI on `api.quicknode.com` (`/streams/rest/openapi.json`, `/webhooks/rest/openapi.json`, `/kv/rest/openapi.json`).

## Compatibility

Use the OpenAPI description for the API you call to determine its current request and response contract. Avoid inferring one product API's behavior from another because Admin API, Streams, Webhooks, KV Store, and the agent endpoints ship independently.

## Deprecation

Check the product's OpenAPI description and changelog before adopting a version. Do not assume a shared sunset period across Quicknode APIs. When an operation is marked `deprecated` or a response supplies `Deprecation` or `Sunset` headers, treat that signal as specific to that product and version.
