MiniMax H3 AI Video Generator API documentation

Authenticate with Authorization: Bearer YOUR_API_KEY. Save the task identifier and query the same capability. Use a stable Idempotency-Key for submission retries.

These are public VidMage field names. The server maps them to provider fields. Input media selects the mode; use its limits together with the parameter table.

Submission and task queries report the available task and usage information. A timeout is not a confirmed failure. Recover the existing task instead of resubmitting.

For face selection and error recovery, follow Task lifecycle. MCP uses the normalized taskId argument in get_task_result, including capabilities whose REST identifier is requestId.

Base charge = duration × the selected resolution rate.

Each reference image beyond 5 adds 10 credits.

Use the Playground or the MCP credit estimator for your exact inputs. Credits and billing.
