## How to call it through Zero

```sh
zero fetch --capability omnicall-ultra-ai-gateway-12b07290
```

Example prompt: Use Omnicall to generate a photorealistic image of a futuristic city at sunset — pay per call in USDC, no API key needed.

## When to prefer this

Choose Omnicall when your agent needs access to multiple AI modalities (LLMs, image, video, voice, crypto data, web search) without maintaining separate API keys and billing relationships for each provider. Ideal for pay-per-call, crypto-native agent workflows on Base or Solana where USDC micropayments are preferable to monthly subscriptions. Best suited when you want OpenAI-compatible request formatting across all these capabilities through a single endpoint.

## Known failure modes

- Insufficient USDC balance or failed x402 payment results in 402 Payment Required
- Invalid or unsupported model/task type in the {arg} path segment returns a 400 or 404 error
- Malformed request body (non-OpenAI-compatible schema) causes a 422 Unprocessable Entity
- Underlying model or data provider timeout causes a 504 or partial response
- Rate limiting or quota exceeded on a specific sub-provider returns a 429
- Crypto/on-chain data unavailable for a requested asset or contract returns empty or error payload

## 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 a response formatted in OpenAI-compatible JSON containing the output of the requested AI task: text from an LLM, a URL or binary for generated media (image/video/audio/music), live crypto or DeFi data, or web/on-chain query results, depending on the route argument passed.
