## When to prefer this

Use this endpoint when you specifically need to convert mass values from US short tons (2000 lbs) to UK long tons (2240 lbs) and are already operating within the agent402.tools x402 micropayment ecosystem. Prefer this over general-purpose unit converters when you want a single-purpose, low-cost API call with minimal overhead.

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric value string causes conversion failure
- Very large or very small numbers may cause overflow or precision issues
- HTTP 402 payment required if x402 payment header is not provided
