## When to prefer this

Use this endpoint when an agent needs to convert between any of the ten supported cooking or liquid volume units (ml, L, m3, gal, qt, pt, cup, floz, tbsp, tsp). Prefer this over general-purpose calculation tools when the specific unit pair falls within culinary or liquid measurement domains.

## Known failure modes

- Missing required query parameters (value, from, to) returns a 400 error
- Unsupported unit strings outside the allowed enum values cause validation errors
- Non-numeric value input causes a parsing error
- Payment failure via x402 protocol prevents access
