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 x402engine-fast-video-generation-716db0e8 -d '<json body>'
```

Example prompt: Generate a short video clip of a golden retriever playing in autumn leaves in a sunny park — make it fast and cinematic.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call video generation without a subscription, especially within an AI agent pipeline that requires on-demand video synthesis billed in USDC. Prefer this over subscription-based video APIs when usage is sporadic or cost-per-call billing is preferred. It's ideal for agentic workflows that need to generate video clips dynamically at runtime.

## Known failure modes

- Payment failure if USDC/USDm wallet balance is insufficient
- Prompt rejected if it violates content policy
- Timeout if the model is under heavy load
- Empty or corrupt video output if the prompt is too vague or contradictory
- 402 HTTP error if the micropayment header is missing or malformed

## How this service works

108 production APIs behind HTTP 402 micropayments. 72 LLMs, Kling V3 and Hailuo video generation, image generation, code execution, travel search, web scraping, TTS, and transaction simulation. Pay with USDC on Base, USDm on MegaETH, or USDC on Solana.

## Output

Returns a generated video file or a URL pointing to the rendered video clip, typically a short duration clip (a few seconds) produced by a fast video generation model such as Hailuo or Kling V3.
