## 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`):

```

Example prompt: What's the current street (parallel) exchange rate for USD to Nigerian Naira, and how big is the spread vs the official CBN rate right now?

## When to prefer this

Choose this endpoint when you need the real-world street or informal-market exchange rate for USD/NGN, not just the official central bank rate — especially for remittance planning, P2P trading, arbitrage detection, or FX risk assessment in Nigeria. Prefer this over official-rate-only endpoints when the gap between official and parallel rates is material to a decision.

## Known failure modes

- Insufficient P2P order book depth may yield a low-confidence or stale rate
- If P2P markets are inactive, the parallel rate may not reflect real-time conditions
- Payment failure (x402) if the $0.01 USDC micro-payment is not completed
- Currency pair not supported will return an error response
- Network timeout if order book data source is temporarily unavailable
