Overview

Requires an active price tier and configured supplier. Accepted tasks retain their original order and price for read-only recovery. Billing uses validated native output seconds; never submit another generation to recover the same task.

After COMPLETED, read run.output.video_url, task_id, duration and resolution. Download the temporary video URL promptly.

Example

Use your own API key and a saved idempotency key for each new job. Replace image or media placeholders with your own publicly reachable HTTPS URLs. Keep the same key and request body when recovering a timeout.

# Set once per job; reuse this key and the identical body after a timeout.
: "${AGENTSKY_IDEMPOTENCY_KEY:?Set a unique, saved key for this job}"
curl --fail-with-body https://gateway.agentsky.dev/v1/run \
  -H "authorization: Bearer $AGENTSKY_API_KEY" \
  -H "content-type: application/json" \
  -H "Idempotency-Key: $AGENTSKY_IDEMPOTENCY_KEY" \
  -d '{"provider":"happyhorse","endpoint":"happyhorse-1.1-t2v","input":{"prompt":"A blue ceramic cup on a white table","duration":5,"resolution":"1080P"}}'
# If status is READY/RUNNING, poll GET /v1/runs/{runId} with the same API key.
