# OpenAPI

> A standard for describing REST APIs in a machine-readable way. Developers generate clients and SDKs from Pachca's OpenAPI spec, and AI agents use it to learn the API

Источник: https://pachca.com/en/glossary/openapi

OpenAPI is an open format for describing REST APIs: endpoints, parameters, request and response formats, errors and authorization. From that file, you can automatically generate client libraries, docs and tests.

What Pachca offers:

- An OpenAPI spec at dev.pachca.com/openapi.yaml
- Arazzo workflows for multi-step processes
- Typed SDKs for TypeScript, Python, Go, Kotlin, Swift and C#
- Pachca CLI, with every API method available as a command

The spec works with code generators (openapi-generator, Kiota, Orval) and with agents that can use OpenAPI directly. For an AI agent, it's an exact map of the API: the agent sees every method and parameter and builds the integration without guesswork.
