What it does

This endpoint animates a static image into a video clip using the Seedance Fast model, accessed through StableStudio's pay-per-generation API. It accepts a source image URL (uploaded via StableStudio's blob upload flow), a text prompt describing the desired motion, and optional parameters for duration (4–12 seconds), resolution (480p/720p/1080p), aspect ratio, audio generation, camera lock, and seed. An optional `last_image` field enables interpolation between two frames.

Payment is handled via the MPP protocol (Tempo method, intent=charge) or x402, settling in USDC on Base (EIP-155:8453). The dynamic price ranges from $0.04 to $0.12 depending on resolution and duration. No API keys are required — authentication and payment happen inline via cryptographic headers. After payment, the endpoint returns a job ID; you poll `/api/jobs/{jobId}` with a SIGN-IN-WITH-X wallet signature until the video is ready (typically ~40 seconds).

Seedance Fast shares the same schema as the full Seedance model but runs at significantly lower cost and faster speed. Images must first be uploaded through StableStudio's three-step upload flow ($0.01) to obtain a blob URL. The endpoint is POST-only and returns 405 on HEAD/GET, which is expected behavior.

Use cases

  • —Animate product photos into short promotional video clips
  • —Generate social media video content from a single still image
  • —Create motion previews from concept art or storyboard frames
  • —Produce interpolation videos between two keyframes
  • —Automate video asset creation in agent workflows without subscriptions

Fit

Best for

  • —Agents needing cheap, fast image-to-video with no subscription
  • —Workflows requiring programmatic video generation with crypto micropayments
  • —Low-cost prototyping of video content from existing images

Not for

  • —Long-form video (max 12 seconds per generation)
  • —Users without a crypto wallet (requires USDC on Base or Tempo)
  • —High-fidelity cinematic output (use full Seedance or Veo 3.1 instead)

Quick start

# 1. POST without payment to get 402 challenge
curl -X POST https://stablestudio.dev/api/generate/seedance-fast/i2v \
  -H 'Content-Type: application/json' \
  -d '{"prompt":"A cat slowly turning its head","image":"https://your-blob-url.vercel-storage.com/cat.png","duration":"5","resolution":"720p"}'
# Returns 402 with PAYMENT-REQUIRED header — decode, sign USDC auth, resend with PAYMENT-SIGNATURE header

Quality

Full OpenAPI schema with detailed input/output definitions, clear pricing, documented payment flow, and agents.txt confirmation. The probe returned 405 (expected for POST-only endpoint probed with HEAD/GET), and the OpenAPI spec confirms the endpoint exists. Slight deduction because no live 402 challenge was captured for this specific endpoint.

Warnings

  • —Probe returned 405 because HEAD/GET were used on a POST-only endpoint; endpoint is likely live but no 402 challenge was directly captured
  • —Images must be uploaded via a separate paid upload flow ($0.01) before use in this endpoint
  • —Requires a crypto wallet with USDC on Base or Tempo L2 for payment
