What it does

This Questflow-hosted x402 endpoint wraps the OpenAI Sora 2 Pro model for video generation. It accepts a simple text prompt and returns a response from the underlying agent. The endpoint supports text-to-video and video remix capabilities, payable per-request with USDC on the Base network.

The x402 challenge is live and requires payment via the exact scheme. The maximum amount per request is 100,000 units of USDC (0x8335…2913 on Base), which at 6 decimals equals $0.10 per call. The endpoint has a generous timeout of 1,200 seconds (20 minutes), reflecting the compute-intensive nature of video generation. The request body is minimal: a single `input` string field containing your prompt or instructions for the agent.

Documentation is sparse — Questflow's main site focuses on their AI Clone trading platform rather than their x402 agent API. No OpenAPI spec, usage examples, or detailed parameter docs were found. The output schema indicates a single `response` string field, but it is unclear whether the response contains a video URL, base64-encoded video, or some other format. Users should experiment with small requests to understand the response structure before building integrations.

The x402 challenge is live with a clear payment scheme and output schema, but documentation is essentially nonexistent. The response format (URL vs. binary vs. base64) is unknown, and no usage examples or detailed parameter docs exist. The listing is functional but requires experimentation.

Warnings

  • —No API documentation found — Questflow docs/pricing/README all return 404
  • —Response format is undocumented — unclear whether the response string contains a video URL, base64 data, or other format
  • —Questflow's main product is an AI trading clone platform; this video generation endpoint may be a secondary or experimental offering
  • —maxAmountRequired of 100000 in USDC (6 decimals) implies ~$0.10 per request, but this is inferred and not explicitly documented
