## 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 coockies-ai-exchange-rates-api-61fd300c -d '<json body>'
```

Example prompt: What's the current exchange rate from USD to EUR right now?

## When to prefer this

Use this endpoint when you need a simple, pay-per-call exchange rate lookup without a subscription, especially within an agentic workflow that already uses x402/Base chain payments. Good for low-volume or one-off queries where subscribing to a dedicated forex API is overkill.

## Known failure modes

- Payment failure — insufficient USDC balance on Base chain returns 402 error
- Invalid currency pair — unsupported or malformed currency codes return error
- Network timeout — Vercel cold start or upstream rate provider unavailable
- Rate limit exceeded — too many requests in a short window
- Missing required parameters — request body lacks required currency fields
