Generate AI video with Google Veo 3 Fast, pay $1.00 per call via x402 on Base.
What it does
This x402 endpoint from Portal Foundation provides AI video generation powered by Google Veo 3 Fast. Each call costs $1.00, payable on-chain via Base (EIP-155:8453) using USDC, USDT, DAI, WETH, or WBTC. The endpoint uses the x402 v2 protocol with a 300-second maximum timeout, which is consistent with the time needed for video generation tasks.
The Portal Create platform describes itself as "AI-powered content creation with Web3 payments" and also appears to offer image generation and AI chat modes, though this specific endpoint is dedicated to video generation. Payment settlement supports multiple transfer methods including EIP-3009 (for USDC) and Permit2 (for USDT, DAI, WETH, WBTC), with gas sponsoring available for several token options.
Documentation is sparse — no OpenAPI spec, no /docs page, and no README were found. The request schema (expected POST body fields such as prompt, duration, resolution, etc.) is not documented in any discovered material, so callers will need to experiment or contact the provider. The endpoint itself is live and returns a proper 402 payment challenge.

Quality
The endpoint is live and returns a well-formed x402 v2 challenge with clear pricing ($1.00 per call, multiple tokens). However, there is no API documentation, no OpenAPI schema, no examples, and the request body format is entirely unknown. The listing is largely inferred from the payment challenge and the brief landing page.
Warnings

- —No /docs, /pricing, or /README pages exist (all return 404)
- —Example request JSON is speculative — the actual required fields are undocumented
- —Response format is unknown; example_response_json is null
