Pay-per-use Sora 2 Pro video generation via x402 micropayments on Base Sepolia
What it does
This endpoint exposes OpenAI's Sora 2 Pro video generation model behind an x402 payment wall, hosted by Questflow. Callers send a POST request with a text prompt (or image description) in the `input` field and, after satisfying the USDC payment challenge on Base Sepolia, receive a generated video response. According to the listing description, videos are produced at 1280×720 resolution with 8-second duration.
The x402 challenge is live and returns a version-1 payment requirement. Payment is accepted via the "exact" scheme on the Base Sepolia testnet, with a max amount of 500,000 units of USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e). The maximum timeout for fulfillment is 1200 seconds (20 minutes), which is consistent with the compute-heavy nature of video generation. The output schema is minimal: a single `response` string field is returned.
Note that this is a development/testnet endpoint (base-sepolia, api-dev subdomain). There is no OpenAPI spec, no dedicated documentation page, and no usage examples beyond what the x402 challenge provides. The underlying provider, Questflow, is primarily an AI agent platform focused on onchain market trading clones; this Sora endpoint appears to be one of several agent-accessible services they expose. Prospective users should be aware of the testnet-only payment rail and the lack of detailed API documentation.

Quality
The x402 challenge is live and provides a basic input/output schema, but there is no OpenAPI spec, no dedicated documentation, no usage examples, and the endpoint runs on a testnet (base-sepolia dev environment). The response format is inferred — the actual response content (URL vs. base64 vs. other) is unknown.
Warnings
- —Testnet only: payments use Base Sepolia USDC, not mainnet
- —Development endpoint (api-dev subdomain) — may be unstable or subject to change
- —No OpenAPI spec or dedicated API documentation available
- —Output format of the response string is unspecified — could be a URL, base64 data, or other
- —Example response is inferred and may not match actual output
