## 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-historical-rates-5ffde8bd
```

Example prompt: What was the EUR to USD exchange rate on March 15, 2024? I need the historical FX rate for that specific date.

## When to prefer this

Choose this endpoint when you need historical (past-date) FX rates for financial calculations, accounting, or analysis and want to pay per call without API key registration. Ideal for AI agents operating autonomously with USDC micropayments on Base. Prefer alternatives if you need real-time live rates, high-volume batch historical data, or regulatory-grade financial data sources.

## Known failure modes

- Invalid or unsupported currency pair returns an error response
- Date out of available historical range returns no data or error
- Malformed schema parameter causes request failure
- Payment failure via x402 protocol results in 402 response blocking data access
- Missing required parameters may return empty or error response
