## 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 veradata-market-signal-44cef066 -d '<json body>'
```

Example prompt: Pull a verified market signal from VeraData for Latin America — use type 'market' and method 'GET' — I need the structured result and the audit hash to confirm data integrity.

## When to prefer this

Choose this endpoint when you need verified, auditable market or economic data specifically covering Latin American markets, especially when data provenance matters (audit hash provided). Prefer this over generic data APIs when operating in LATAM-focused workflows and when x402 micropayment infrastructure is already set up.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required returned
- Missing required 'type' or 'method' fields in input — 400 Bad Request
- Invalid or unsupported signal type or method — may return error or empty result
- Network timeout reaching api.veradata.dev — agent should retry
- Audit hash mismatch or verification failure — data integrity concern

## How this service works

Verified Latin American Data for Autonomous AI Agents — x402 micropayments
