# SDKs & client libraries

> Maintained clients, generated libraries, and the OpenAPI source for agent-generated clients.

Prefer the maintained Python SDK or CLI. The other packages are generated from
the OpenAPI spec and receive lighter maintenance.

## Generate a client with your agent

For another language, give your coding agent the
[public OpenAPI spec](https://docs.legnext.ai/openapi.yaml) and
the [agent-ready reference corpus](https://docs.legnext.ai/llms-full.txt).
Ask it to keep `LEGNEXT_API_KEY` server-side and implement the complete
submit → wait → persist flow.

<Note>
  Generation tasks are asynchronous. Poll
  [`GET /v1/job/{job_id}`](/api-reference/task-management/get-task) or use a
  webhook, then download outputs before their remote URLs expire.
</Note>

<Note>
  The PHP client source exists on GitHub but is not listed here until its Composer
  package is publicly installable.
