## 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 ddg-markets-spread-endpoint-88dded9a -d '<json body>'
```

Example prompt: Can you fetch the current bid-ask spread for the BTC/USDC market from the DDG markets API?

## When to prefer this

Choose this endpoint when you need real-time or current market spread data for financial instruments and are operating in an agent context that supports x402 micropayment rails. Best suited for automated trading agents, arbitrage detection, or any workflow requiring programmatic access to bid-ask spread data at low per-call cost.

## Known failure modes

- Missing required input body fields returns a validation error
- Invalid market identifier results in a 404 or empty response
- Insufficient USDC payment (requires $0.01 per call) results in a 402 Payment Required
- Malformed JSON body causes a 400 Bad Request
