How this service works
Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.
Output
Returns a JSON object with the original kilometers value and the equivalent miles value (e.g. {"miles": 0.621371, "kilometers": 1}). The conversion uses the standard factor of 0.621371192237334 miles per kilometer.
Example use cases
Marathon distance in imperial
“I'm training for a 42.195 kilometer marathon — how many miles is that exactly?”
Road trip distance conversion
“My GPS says the destination is 350 kilometers away. How many miles is that?”
Speed limit or fitness tracker unit swap
“My fitness app logged 5 kilometers today. Can you tell me how many miles that is?”
Technical details
Endpoint
GEThttps://agent-chain-kit-solana.vercel.app/v1/convert-kilometers-to-miles?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, server-side kilometers-to-miles conversion without implementing the math locally. Ideal for AI agents operating in the x402 pay-per-call ecosystem that already handle micropayments and need a reliable, consistent unit conversion utility alongside other calls to the same host (weather, FX, EVM reads).
Side effects
- Missing required 'kilometers' query parameter returns a 400 or error response
- Non-numeric value for kilometers causes a validation error
- Negative kilometer values may return a result but should be validated by the caller
- Payment not included or invalid x402/MPP payment leads to 402 Payment Required response
