Use this endpoint when you need a simple, programmatic weight unit conversion without maintaining your own conversion logic. It is suitable for single-call, real-time conversions paid per-use via USDC x402, ideal for agents that don't want to embed conversion tables or handle unit math internally.
Side effects
- Invalid or unrecognized unit names returns an error
- Missing required query field returns a validation error
- Unsupported unit combination (e.g. converting weight to volume) may return an error or null result
- Malformed input value (non-numeric) may return a parsing error
