## 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-api-fx-crypto-price-lookup-76423d39
```

Example prompt: What's the current exchange rate for USD against EUR, GBP, and JPY? Also, how much would 250 USD convert to in each of those currencies?

## When to prefer this

Choose this endpoint when an AI agent needs real-time FX or crypto exchange rates paid microtransactionally per call via USDC/x402, without requiring API key setup or subscriptions. Ideal for lightweight, on-demand currency queries within agent workflows that already support x402 payment.

## Known failure modes

- Invalid or unsupported 3-letter currency code returns an error
- Missing base currency parameter results in a 400 bad request
- Payment failure via x402 protocol (insufficient USDC funds) blocks the request
- Network timeout if the upstream FX data provider is unavailable
- Requesting an unsupported crypto symbol may return empty or error response

## How this service works

Pay-per-call data services for AI agents: web extraction (text, Markdown, metadata), PDF-to-text, RSS/Atom parsing, FX and crypto prices, weather, DNS and email validation. All paid endpoints use the x402 payment protocol (USDC).

## Output

Returns current exchange rates for the specified base currency against one or more target currencies, and optionally the converted value of a given amount. Response includes rate data per currency pair.
