It is part of a broader pay-per-generation platform that offers multiple AI image and video models with no subscriptions or API keys required. Payment is handled via USDC micropayments on Base (x402/MPP protocol with Tempo settlement).\n\nThe Seedance Fast t2v endpoint accepts a text prompt and optional parameters including duration (4–12 seconds), resolution (480p, 720p, or 1080p), aspect ratio (16:9, 9:16, 4:3, 3:4, 1:1, 21:9), audio generation, camera lock, and a reproducibility seed. Pricing is dynamic, ranging from $0.04 to $0.12 per generation depending on resolution and duration, with typical generation time around 40 seconds. This is the budget-friendly variant of the full Seedance model ($0.33–$0.99).\n\nThe workflow is asynchronous: POST the generation request with a signed USDC payment header, receive a jobId, then poll `GET /api/jobs/{jobId}` (authenticated via SIGN-IN-WITH-X wallet signature) until the job completes and returns a videoUrl. The endpoint uses the standard x402/MPP 402 payment challenge flow. Note that this endpoint only accepts POST requests — HEAD and GET return 405, which is expected behavior.","tags":["image","video","generation","nano-banana","gpt-image","grok","flux","sora","veo","seedance","wan"],"capabilities":["text-to-video","seedance-fast","micropayment-gated","usdc-on-base","async-job-polling","configurable-duration","configurable-resolution","configurable-aspect-ratio","audio-generation","camera-lock","reproducible-seed","mpp-tempo","x402"],"categories":["video","vision"],"synonyms":["text to video","t2v","seedance","video generation","AI video","prompt to video","text2video","seedance fast","stablestudio video"],"warnings":["Direct 402 challenge was not captured for this specific endpoint — HEAD and GET returned 405 (expected for POST-only route)","Pricing is dynamic; actual cost per generation varies by resolution and duration within the $0.04–$0.12 range","Requires a crypto wallet with USDC on Base network for payment"],"endpointUrl":"https://stablestudio.dev/api/generate/seedance-fast/t2v","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stablestudio.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.820","qualityRationale":"Full OpenAPI schema with detailed input/output definitions, comprehensive x-guidance documentation, clear pricing, and well-documented async job flow.
