# StableStudio Seedance Text-to-Video Generation

> StableStudio Seedance Text-to-Video Generation is a paid API for AI agents from stablestudio.io, paid per call via x402, $20/call, status unknown (last checked 2026-09-15).

Generates a video from a text prompt using the Seedance T2V model, returning a job ID for async retrieval

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stablestudio-seedance-text-to-video-generation-6129961f -d '<json body>'
```

Example prompt: Use StableStudio to generate a video of a lone astronaut walking across a red Martian landscape at sunset, in 16:9 aspect ratio at 1 MP resolution, PNG output at quality 90, with safety tolerance 2.

## When to prefer this

Choose this endpoint when you need pay-per-use text-to-video generation without a subscription, specifically using the Seedance T2V model via StableStudio. Prefer this over subscription-based video platforms when cost predictability per generation matters, or when integrating into an agentic workflow that needs async job-based video creation with configurable resolution and aspect ratio.

## Known failure modes

- Prompt too long (exceeds 10,000 characters) — validation error
- Invalid enum value for resolution, aspect_ratio, or output_format — schema validation error
- Safety tolerance out of range (must be 1-5) — validation error
- Payment failure or insufficient USDC — 402 payment required error
- Model overload or queue timeout — job may remain pending indefinitely
- Seed value out of integer bounds — validation error
- Empty or missing prompt — required field error

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

A JSON object containing the job type ('seedance-t2v'), a unique jobId string for polling the result, the current status ('pending'), and a success boolean. The agent must use the jobId to retrieve the completed video once processing finishes.
