```

Example prompt: Convert 100 USD to EUR for me — I need the exchange rate and the final converted amount.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use FX rate lookup and currency conversion with a minimal cost per call ($0.002 USDC), especially in x402-compatible agent workflows that handle micropayments automatically. Suitable when you need a lightweight, on-demand conversion without a subscription or API key.

## Known failure modes

- Missing required 'from' or 'to' query parameters returns an error
- Invalid or unsupported currency code returns an error or empty rate
- Payment of 0.002 USDC not provided results in HTTP 402 payment required
- Network or upstream FX data source unavailability may return a 5xx error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
