## 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-chat-completions-ea7c5cb3 -d '<json body>'
```

Example prompt: Use Omnicall to generate a short product description for my new coffee brand — route it through any available GPT-4 class model and pay per call in USDC on Base, no API key needed.

## When to prefer this

Choose this endpoint when you need access to a wide variety of LLMs (247+) without managing individual API keys or subscriptions, especially when your agent operates in a crypto-native environment and can pay per call in USDC on Base or Solana. Ideal for agents that need flexible model routing, occasional bursts of inference without committed spend, or access to media/crypto/web capabilities through a single OpenAI-compatible interface.

## Known failure modes

- Insufficient USDC balance — payment fails and call is rejected
- Invalid or unsupported model name returns 400 or routing error
- Malformed messages array causes 422 validation error
- Network congestion on Base/Solana delays payment confirmation
- Rate limiting if too many concurrent calls are attempted
- Unsupported output format hint silently ignored or returns error

## 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

An OpenAI-compatible chat completion response containing the model's generated text output, structured as a standard choices array with message content, returned after a $0.02 USDC per-call payment on Base or Solana.
