## When to prefer this

Use this endpoint when you need a quick, programmatic quarts-to-liters conversion without implementing the math yourself, especially in agent workflows that handle US customary to metric volume conversions. Prefer this over manual calculation when consistency and correctness are required at $0.001 per call.

## Known failure modes

- Missing 'value' query parameter returns an error or bad request
- Non-numeric value passed as query parameter causes conversion failure
- Payment not fulfilled results in HTTP 402 response blocking the conversion
- Extremely large or small numeric values may cause overflow or precision issues
