# x402 AI Gateway – FX/ANG/MMK Currency Converter

> x402 AI Gateway – FX/ANG/MMK Currency Converter is a paid API for AI agents from api.fastapi.online, paid per call via x402, $0.0002/call, status unknown (last checked 2026-10-12).

Converts a specified amount from one currency (likely ANG or a related pair) to MMK (Myanmar Kyat) using a micropayment-gated API endpoint.

## 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-mmk-currency-converter-4714ffb0 -d '<json body>'
```

Example prompt: Convert 250 ANG to MMK for me — I need to know the Myanmar Kyat equivalent right now.

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call currency conversion specifically for the ANG-to-MMK pair and are operating in an x402 micropayment-enabled environment. It is ideal for agents that can autonomously handle USDC micropayments on Base without manual authorization overhead. Avoid if you need broad multi-currency support, high reliability SLAs, or if your agent cannot handle HTTP 402 payment flows.

## Known failure modes

- Payment not included or insufficient — returns HTTP 402 requiring USDC micropayment on Base before proceeding
- Invalid or missing amount field — may return a validation error or use default of 1
- Unsupported currency pair — endpoint may return an error if the FX pair is not supported
- Service unavailable — self-hosted infrastructure may be offline or rate-limited
- Network timeout — self-hosted endpoint may have higher latency or downtime than managed APIs

## How this service works

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

## Output

Returns a JSON object containing the converted currency value from ANG (or source currency) to MMK (Myanmar Kyat) for the specified amount, likely including the exchange rate or result value.
