## What it is
The official OpenAPI 3.1 specification describing the OpenAI REST API, including endpoints, authentication, parameters, and request/response schemas. It serves as the source of truth from which OpenAI's official SDKs are generated and can be used in any OpenAPI-compatible tooling.

## Use cases
- generate typed client SDKs for the OpenAI API
- import the OpenAI API into Postman or Swagger UI
- build an API explorer for OpenAI endpoints
- configure mock servers or testing tools against the OpenAI API
- validate request and response schemas when calling the OpenAI API
- keep custom integrations in sync with the latest OpenAI API surface

## When to choose
- you need a machine-readable, up-to-date description of the OpenAI REST API
- you are generating a client in a language without an official SDK
- you want to build tooling like explorers, mocks, or validators on top of the OpenAI API

## When to avoid
- you just want to call the OpenAI API - use an official SDK like openai-python or openai-node instead
- you need human-readable guides and tutorials - use the OpenAI API documentation site
- you need a spec for a non-OpenAI or OpenAI-compatible third-party API
