## 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-to-bdt-currency-converter-9a09c69a -d '<json body>'
```

Example prompt: Convert 500 Argentine Pesos to Bangladeshi Taka for me.

## When to prefer this

Choose this endpoint when you specifically need ARS-to-BDT conversion and are operating in an x402-enabled micropayment environment on Base (USDC). Suitable for agents that can handle 402 payment flows automatically. Not ideal if you need multi-currency or bulk batch conversions, or if your agent cannot process x402 payments.

## Known failure modes

- Payment not provided or insufficient — 402 Payment Required response before conversion executes
- Invalid or missing 'amount' field — may return a validation error or default to converting 1 unit
- Downstream exchange rate data unavailable — may return an error or stale rate
- Network timeout on the self-hosted gateway

## How this service works

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

## Output

Returns an object containing the converted currency value from ARS to BDT, likely including the converted amount and possibly the rate used, after a successful x402 USDC micropayment of $0.0002 on Base.
