Get Job Status

GET https://api.inquantum.ai/v1/videos/{job_id}

The response includes status, outputs, usage, cost, timestamps, and an error object when the generation fails.

Download Content

GET https://api.inquantum.ai/v1/videos/{job_id}/content
GET https://api.inquantum.ai/v1/videos/{job_id}/content?index=0

The content route returns or redirects to the selected output. Use a valid Planck API key for the organization that submitted the generation. See the Video Generation guide for the complete workflow, validation, billing, and tracking behavior.

This endpoint uses the shared AI Gateway error envelope. See the Error Handling & Fallback guide for response examples, retry rules, fallback behavior, and streaming errors.
