## 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 omnicall-ai-gateway-v1-x-arg-endpoint-97b385cd
```

Example prompt: Using Omnicall's pay-per-call gateway, generate an image of a sunset over the ocean using the best available image model — I'll pay in USDC on Base, no API key needed.

## When to prefer this

Choose this endpoint when your agent needs access to a wide range of AI capabilities (LLMs, media generation, crypto data, web search) without managing multiple API keys or subscriptions, and when you want to pay per call in USDC on Base or Solana rather than committing to a monthly plan. Ideal for autonomous agents that need flexible, multi-modal AI access with crypto-native payment rails.

## Known failure modes

- Insufficient USDC balance — payment fails and request is rejected with a 402 Payment Required
- Invalid or unsupported {arg} route — returns 404 or error if the model/capability slug is unrecognized
- Malformed request body — returns 400 if prompt or parameters are missing/invalid
- Upstream model timeout — returns 504 or error if the backing LLM or media model is unavailable
- Rate limiting — too many concurrent calls may result in throttling or 429 errors

## How this service works

Omnicall is the all-in-one agent gateway: 247 LLMs plus image, video, voice & music generation, live crypto/DeFi/prediction-market data, web search and on-chain reads — one OpenAI-compatible endpoint, pay per call in USDC on Base or Solana, no API key.

## Output

The agent receives the output of the requested AI capability: a text completion, generated media file or URL, live crypto/DeFi market data, or web search results, returned in an OpenAI-compatible response format after a $0.04 USDC per-call payment on Base or Solana.
