## 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 losbeto-price-foreign-exchange-rate-lookup-54e71bcc
```

Example prompt: What's the current exchange rate with USD as the base currency? I need the live forex rate right now — no API key, just pay per call.

## When to prefer this

Choose this endpoint when you need a quick, keyless, pay-per-call forex rate lookup with no account setup, especially in agentic or automated workflows that already use USDC micropayments via x402. It is ideal for single-currency-pair spot rate retrieval with low overhead. Prefer alternatives if you need multi-pair batch rates, historical data, or guaranteed SLA.

## Known failure modes

- Missing required 'base' query parameter returns an error
- Invalid or unsupported currency code may return an error or unexpected result
- Payment failure (insufficient USDC balance or wrong chain) results in HTTP 402 without data
- Upstream exchangerate-api.com outage may cause failure or stale data
- Rate limiting or node-level issues may cause intermittent unavailability

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.

## Output

Returns a JSON object with a Unix timestamp, the exchange rate value as a number, the base currency parameter used, the upstream source (exchangerate-api.com), and a recommended_next array suggesting other endpoints on the node that week along with their prices in USDC.
