## 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-eco-tier-d52aa76a
```

Example prompt: Use Omnicall's eco endpoint to generate an image of a futuristic city at sunset — pay per call in USDC on Base, no API key needed.

## When to prefer this

Choose this endpoint when an AI agent needs to call any of 247 LLMs or generate media/audio/video without managing multiple API keys or subscriptions, and when micropayment billing in USDC on Base or Solana is acceptable. Ideal for autonomous agents that need broad AI capability access with no upfront credential setup.

## Known failure modes

- Insufficient USDC balance — payment fails before task executes
- Invalid or unsupported 'arg' route — returns 404 or bad request
- Model not available or overloaded — returns 503 or timeout
- Malformed request body — returns 400 validation error
- On-chain payment confirmation delay — request held pending settlement
- Rate limiting on eco tier — returns 429 too many requests

## 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

Returns an OpenAI-compatible response object containing the output of the requested AI task: text completion, generated media URL, live crypto/DeFi data, or web search results, depending on the 'arg' route specified.
