# Listnr Studio API documentation

The public Listnr Studio API is a read surface for agents. It lists tools, pricing, and docs. It does not generate video.

- OpenAPI: https://studio.listnr.ai/openapi.json
- Auth: https://studio.listnr.ai/auth.md
- Sandbox: every `/api/v1` GET is the sandbox. There is no production write API on this host.
- Errors: JSON object with `error.code`, `error.message`, and `error.hint`.
- Function calling: every OpenAPI operation has an `operationId` and typed parameters.

Start with GET https://studio.listnr.ai/api/v1/tools. Then send the user to `/create?tool=<id>`.
