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.\n\nThe 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.\n\nDocumentation 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.","tags":[],"capabilities":["video-generation","google-veo-3-fast","x402-payment","base-l2-settlement","multi-token-payment","usdc","usdt","dai","weth","wbtc","gas-sponsoring"],"categories":["video","ai-generation"],"synonyms":["AI video generator","text-to-video","Veo 3","video synthesis","AI video creation","Google Veo","Portal Foundation video","web3 video generation"],"warnings":["No API documentation or OpenAPI spec found; request body schema is unknown","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"],"endpointUrl":"https://gen.portalfoundation.ai/api/generate-video","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xE68e6015F540C9778Ad130E155a4c0265EA65D40","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://gen.portalfoundation.ai/api/generate-video","description":"AI Video Generation with Google Veo 3 Fast","outputSchema":{"input":{"type":"http","method":"POST","bodyType":"json","bodyFields":{"model":{"enum":["sora2-720p","sora2-pro-720p","sora2-pro-1080p","veo3-fast","veo3","veo3-audio","kling-1.6-std","kling-1.6-pro","kling-2.1-std","kling-2.1-master","seedance-lite-720p","seedance-pro-1080p"],"type":"string","required":false,"description":"Model ID"},"prompt":{"type":"string","required":true,"description":"Text description of the video to generate"},"duration":{"type":"number","required":false,"description":"Video duration in seconds (default: 5)"}}},"output":{"model":{"type":"string","description":"Model used for generation"},"duration":{"type":"number","description":"Duration of generated video"},"videoUrl":{"type":"string","description":"URL of the generated video"}}},"maxAmountRequired":"1000000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a well-formed x402 v2 challenge with clear pricing ($1.00 per call, multiple tokens).
