How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with a 'result' object containing the converted value, a 'success' boolean (always true on success), and a 'computation' string describing in plain language what was computed (e.g. '75 kilograms = 165.35 pounds').
Example use cases
Recipe ingredient unit conversion
“I have a recipe that calls for 250 grams of flour but my scale only does ounces — what's that in ounces?”
Shipping weight compliance check
“I need to convert a package weight of 3.5 pounds into kilograms so I can fill out this international shipping form.”
Fitness tracker unit normalization
“My gym tracker shows my goal weight as 185 pounds — can you convert that to kilograms for me?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/convert/weightWhen to prefer
Use this endpoint when you need a fast, serverless, dependency-free weight unit conversion in an agent pipeline — especially when paying per-call via x402 micropayments on Base is acceptable and you want a dedicated math computation service rather than a general-purpose LLM or a heavy unit-conversion library.
Side effects
- Unknown or unsupported unit strings in 'from' or 'to' fields return an error
- Missing required fields ('from', 'to', 'value') cause a 400-level error
- Non-numeric 'value' input causes a validation failure
- Incompatible unit categories (e.g. passing a length unit to a weight endpoint) may return an error or unexpected result
