## 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-ars-bam-currency-converter-29e76599 -d '<json body>'
```

Example prompt: Convert 500 Argentine pesos to Bangladeshi taka for me.

## When to prefer this

Use this endpoint when you specifically need to convert Argentine Pesos (ARS) to Bangladeshi Taka (BAM) and are operating in an x402-capable agent environment that can handle USDC micropayments on Base. It is purpose-built for this currency pair and costs only $0.0002 USDC per call, making it suitable for high-frequency or automated conversion lookups.

## Known failure modes

- Payment not provided or rejected — 402 Payment Required response before execution
- Invalid or missing amount field — may return a validation error or default to 1
- Service unavailable or gateway timeout — 5xx error from self-hosted infrastructure
- Stale exchange rate data if the self-hosted instance is not updated frequently
- Unexpected response schema — the response schema is unspecified (empty object)

## How this service works

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

## Output

Returns the converted currency value representing the given ARS amount expressed in Bangladeshi Taka (BAM), likely including the converted figure and possibly the exchange rate used.
