```

Example prompt: Convert 250 kilometers to miles for me — I need the exact numeric result.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call unit conversion settled in USDC on Base via x402 — particularly in crypto-native or agent workflows where microtransaction billing is preferred over subscription APIs. Useful when integrating with other ScriptMasterLabs x402 endpoints (e.g. RWA, gas tracker) in the same pipeline.

## Known failure modes

- Unsupported or unrecognized unit type returns an error or empty result
- Missing required query parameters (value, from, to) cause a 400-style error
- Payment via x402 fails if wallet has insufficient USDC balance on Base
- Hosted on Render free tier — cold start latency or downtime possible
- Ambiguous unit abbreviations (e.g. 't' for ton vs tonne) may yield unexpected conversions
