## When to prefer this

Choose this endpoint when you need a simple, pay-per-call unit conversion or utility computation and are already operating within an x402 USDC payment flow on Base. It is well-suited for AI agents that need lightweight, on-demand conversions without setting up a dedicated conversion library.

## Known failure modes

- Missing or malformed queryParams returns an error response
- Unsupported unit type or conversion pair returns an error
- Payment failure (x402 payment not completed or insufficient USDC) results in 402 response
- Invalid input values (non-numeric) may return a 400 or error object
