## 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 agent-data-tools-currency-exchange-rates-06b822ab
```

Example prompt: What's today's ECB exchange rate from USD to EUR and GBP, and how much would 250 USD convert to in each?

## When to prefer this

Choose this endpoint when you need authoritative ECB reference exchange rates without requiring an API key or account setup, and you want pay-per-call micro-pricing in USDC. Ideal for AI agents needing occasional or burst currency lookups where subscription APIs are overkill. Best for EUR-anchored reference rates; if you need real-time mid-market or bid/ask spreads from banks, prefer a dedicated forex data provider.

## Known failure modes

- Invalid or unsupported ISO 4217 currency code returns an error
- ECB rates not yet published for the current day (rates publish ~16:00 CET on working days) may return previous day's rates
- Missing required 'from' parameter returns a 400-level error
- Payment failure or insufficient USDC balance blocks the request via x402
- Network or Cloudflare Worker timeout

## How this service works

Read public static documentation as text or Markdown with code, tables, headings and links for $0.002 USDC on Base via x402. Inspect real cached examples and an unsigned quote, then buy with a capped Node CLI. No account or API key. No JavaScript rendering, authenticated or paywalled access. Other paid utilities remain available.

## Output

A JSON object containing the base currency, requested target currencies with their exchange rates, the optional converted amounts if an amount was specified, the ECB rate date (published around 16:00 CET on working days), and a timestamp for when the rates were checked.
