## 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 vibes-api-hub-pre-trade-endpoint-32b98f53 -d '<json body>'
```

Example prompt: Can you run a pre-trade check on ETH/USDC for me before I place a buy order — I want to see the current market conditions and any signals I should know about?

## When to prefer this

Use this endpoint when an AI agent needs to perform pre-trade due diligence or fetch market signals before executing a crypto or financial trade, especially when operating within a pay-per-call x402 micropayment workflow on Base chain. Prefer this over general market data APIs when operating in a Coinbase/Base ecosystem context with automatic payment handling.

## Known failure modes

- Payment not included or insufficient USDC balance returns 402 Payment Required
- Unsupported trading pair or symbol returns 404 or error response
- Upstream market data provider unavailable returns 503
- Rate limiting or quota exceeded returns 429
