## 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 x402-toolbox-fx-exchange-rates-640ede7b
```

Example prompt: What are the current exchange rates from USD to EUR and JPY? I need the latest FX data for a payment calculation.

## When to prefer this

Choose this endpoint when you need FX rate lookups without signing up for a traditional API key or subscription — payment via x402/USDC micropayment serves as identity. Ideal for AI agents that need on-demand, pay-per-call currency data with no monthly commitment. Best suited for low-frequency lookups where per-call pricing at $0.002 USDC is economical versus a full forex API subscription.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported currency pair in schema parameter — may return empty or error response
- Network timeout on Cloudflare Worker — returns 5xx error
- Malformed schema parameter — returns validation error
- Rate data temporarily unavailable from upstream FX provider — returns error with ok: false

## How this service works
