Find the guides and endpoint references. Read the [full documentation text](/llms-full.txt) for tools that ingest a single document. Use **Copy page** on an individual page for Markdown content. ## Model a long-running tool A caption job is asynchronous. Expose at least two operations in your connector: 1. **Create captions**: call `POST /v1/subtitles` with a stable idempotency key and return the job ID. 2. **Get result**: call `GET /v1/jobs/{id}` to return status, progress, and completed output URLs. You can also expose cancellation, preset discovery, and usage checks. Keep the API key in the connector's server-side secret store. ## Integration rules * Check the prepaid balance and the video's expected duration before submission. * Require a direct HTTPS media URL; an agent cannot pass a local file path. * Save the job ID as soon as submission succeeds. * Poll no more often than every five seconds per job and honor `Retry-After`. * Stop on `completed`, `failed`, or `canceled`. * Treat processing errors as tool results the caller can act on. * Save output files before their 24-hour expiration. * Preserve the idempotency key on network retries; create a new key only for a new job. ## Platform connectors The REST API and OpenAPI specification can be used as the basis for a platform connector. Platform-specific manifests, authorization requirements, and submission approval still need to be implemented and verified for the target platform. This documentation does not imply a published or approved Muse connector.
