How this service works
Pure computation endpoints paid per call via x402 ($0.001 USDC on Base).
Output
Returns a JSON object with 'result' (the converted numeric value as a float) and 'unit' (a string label for the target unit, e.g. 'celsius').
Example use cases
Recipe ingredient weight conversion
“I have a recipe that calls for 400 grams of flour — how many ounces is that?”
Running distance unit swap
“I ran 10 kilometers today, what's that in miles?”
Body temperature fever check
“My thermometer reads 39.5 degrees Celsius — what is that in Fahrenheit?”
Technical details
Endpoint
POSThttps://compute-api-production-245d.up.railway.app/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, programmatic, pay-per-use unit conversion for temperature (fahrenheit, celsius, kelvin), length (meters, kilometers, feet, miles), or mass (grams, kilograms, ounces, pounds) with no rate limits or API keys — just micro-payments via x402 on Base.
Side effects
- Invalid or unsupported unit enum value returns an error — only the listed enums are accepted (e.g. 'celcius' misspelled will fail)
- Incompatible unit categories (e.g. converting meters to kilograms) will likely return an error or nonsensical result
- Missing required fields ('to', 'from', or 'value') will cause a 4xx validation error
- Payment failure or insufficient USDC balance will result in a 402 Payment Required response
- Extremely large or small numeric values may produce floating-point precision issues
