Kilometer-per-Hour to Meter-per-Minute Speed Converter
x402
Kilometer-per-Hour to Meter-per-Minute Speed Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).
Converts a speed value from kilometers per hour (km/h) to meters per minute (m/min) using IEEE-754 double precision arithmetic.

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing the original value in km/h, the converted value in meters per minute, the source and target unit labels, the dimension ('speed'), and the numeric precision used (IEEE-754 double).
Example use cases
Running pace unit conversion
“I'm training for a race and my treadmill shows 12 km/h — convert that to meters per minute so I can track my pace more easily.”
Engineering speed specification check
“Our conveyor belt runs at 0.5 km/h — what is that in meters per minute so I can match it against the spec sheet?”
Physics homework speed problem
“Can you convert 72 km/h to meters per minute? I need both the original value and the converted result for my physics problem.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/speed/kilometer-per-hour-to-meter-per-minute?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a reliable, schema-validated, IEEE-754 double-precision conversion specifically from km/h to m/min via a simple GET request. Prefer this over manual calculation when you need a verifiable, consistent result with documented precision, especially in automated agent workflows where correctness matters.
Side effects
- Missing required 'value' query parameter returns an error
- Negative values are rejected (minimum is 0)
- Values exceeding 1e+100 are rejected by schema validation
- Non-numeric input for value parameter causes a 400-level error
- Payment failure (x402) blocks the request if USDC micropayment is not fulfilled
