## 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-ai-gateway-fx-ang-to-ngn-currency-converter-da11de9b -d '<json body>'
```

Example prompt: Convert 75 ANG to Nigerian Naira for me — I need to know how much that is in NGN right now.

## When to prefer this

Use this endpoint when you specifically need ANG-to-NGN currency conversion with a pay-per-call micropayment model via x402/USDC on Base, particularly in agentic workflows where you want no subscription overhead and low per-call cost ($0.0002 USDC).

## Known failure modes

- 402 Payment Required if x402 USDC micropayment on Base is not provided or fails
- Invalid or missing amount field returns an error
- Network or gateway timeout from self-hosted infrastructure
- Amount field validation failure if a non-numeric value is provided

## How this service works

Self-hosted AI API gateway. Expensive endpoints require an x402 micropayment (USDC on Base) before executing.
