# Otto AI x402 — AI Video Generation (video-gen)

> Otto AI x402 — AI Video Generation (video-gen) is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $1.75/call, status unknown (last checked 2026-09-14).

Generates short AI videos from a text prompt (and optional image) using models like Seedance, Sora, or Veo, returning a hosted MP4 URL.

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 otto-ai-x402-ai-video-generation-video-gen-8929d3f2 -d '<json body>'
```

Example prompt: Generate a 6-second 16:9 video using the Sora-2 model of a golden retriever running through a sunlit meadow with slow camera pan — pay with USDC.

## When to prefer this

Use this endpoint when an AI agent needs to generate short-form video (4–10 seconds) from a text prompt or image, and wants to choose from premium models (Seedance, Sora-2, Sora-2-Pro, Veo-3.1) with per-call USDC micropayment pricing. Prefer this over image-generation endpoints when motion and scene animation are required, and over full video production platforms when a single short clip is sufficient.

## Known failure modes

- Prompt too short or too long (must be 20–1000 chars) — returns error
- Duration out of range for selected model (4–10 seconds enforced) — returns error
- Invalid model name not in enum — returns error
- Payment failure or insufficient USDC balance — request rejected before generation
- Upstream model provider timeout or failure — returns status: failed with error message
- Invalid image_url for image-to-video — returns error

## How this service works

AI video generation via fal.ai — default model: ByteDance Seedance 2.0. Alternatives: fal-ai/sora-2/text-to-video, fal-ai/veo3.1. Dynamic pricing per request: at-cost fal.ai rate + 15% margin (floor $0.05); the advertised price is the Seedance 5s reference quote — the actual quote is returned per request. Supports text-to-video and image-to-video.

## Output

A JSON object containing a hosted MP4 video URL, the model used, resolution (e.g. 720p), duration in seconds, price in USDC, and a success/failed status string.
