Technical details
Endpoint
GEThttps://agent402.tools/api/convert/tonnes-to-grainsWhen to prefer
Use this endpoint when you need a precise programmatic conversion from metric tonnes to grains — particularly in contexts involving apothecary, ballistics, gemology, or historical weight systems that use grains as a base unit. Prefer this over a general-purpose calculator when operating within an x402-enabled agent workflow that handles micropayments automatically.
Side effects
- Missing or non-numeric value parameter returns an error
- Value parameter that is not a valid number (e.g. letters) causes a bad request response
- Network or service unavailability results in a timeout or 5xx error
- Payment of 0.001 USDC not provided results in a 402 Payment Required response
