## When to prefer this

Use this endpoint when you need a quick, programmatic conversion from grains to micrograms specifically, particularly in pharmaceutical, scientific, or precision measurement workflows where both units are relevant. Prefer this over manual calculation when integrating into an automated agent pipeline that handles mass unit conversions.

## Known failure modes

- Missing or non-numeric value parameter returns an error
- Negative or zero values may return unexpected results
- Payment failure via x402 protocol results in 402 response and no conversion
- Extremely large numeric values may cause precision or overflow issues
