## When to prefer this

Use this endpoint when you specifically need to convert Argentine Peso (ARS) amounts to Bulgarian Lev (BGN). It is part of a self-hosted AI gateway that charges a tiny per-call micropayment in USDC, making it suitable for programmatic, automated, or high-frequency conversions where a flat low cost per call is acceptable.

## Known failure modes

- Missing or invalid amount field may result in a default conversion of 1 unit
- Exchange rate data unavailable or stale could return an error or outdated result
- Payment failure (x402 USDC micropayment not completed) will block the request
- Malformed request body returns 4xx error
