## 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 omniapi-ai-completion-endpoint-be1b88a3 -d '<json body>'
```

Example prompt: Run this query through the OmniAPI AI completion endpoint and get me a response: 'Summarize the key differences between proof-of-work and proof-of-stake blockchains in three bullet points.'

## When to prefer this

Choose this endpoint when you need AI text completions within a crypto-native, pay-per-call architecture using x402 USDC micropayments, and you want to avoid subscription-based AI APIs. Best suited for agents operating in Web3 or multi-chain environments that already handle x402 payment flows.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted, returning 402 Payment Required
- Missing required 'query' field returns a 400 Bad Request or validation error
- Malformed JSON body causes a 400 or 422 error
- Model timeout or overload may return a 503 or 504 error
- Empty or nonsensical query may return a low-quality or empty completion
