## 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-finance-hub-forex-rate-lookup-d0824a77 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need a real-time forex exchange rate between two currency pairs and can pay per-call in USDC on Base via the x402 protocol. Prefer this over free rate APIs when freshness, reliability across multiple data providers, and programmatic micropayment access matter.

## Known failure modes

- Missing required 'from' or 'to' fields returns a validation error
- Unsupported or invalid currency codes may return an error or empty data
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Upstream provider (Alpha Vantage, Twelve Data) outage causes unavailable data
- Rate limiting from upstream providers may delay or fail response
