## 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 molcloud-fx-currency-exchange-rate-lookup-59ec4921
```

Example prompt: What are the current exchange rates from USD to EUR, GBP, JPY, CAD, AUD, and CHF for an amount of 250 dollars?

## When to prefer this

Choose this endpoint when an AI agent needs lightweight, pay-per-use FX rate lookups without a subscription, especially in autonomous workflows that settle micropayments via x402/USDC on Base. Ideal for agents that occasionally need currency conversion data rather than high-frequency trading feeds.

## Known failure modes

- Invalid or unsupported currency code returns an error or empty rate map
- Missing required 'input' wrapper causes schema validation failure
- Payment not settled in USDC on Base results in 402 rejection before the request is processed
- Rate provider downstream outage may return a 500 or degraded response

## How this service works

41 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

## Output

A JSON object containing the base currency, a map of target currency codes to their exchange rates relative to the base, plus a status field confirming success and the endpoint path that was called.
