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 watt-hours, the converted value in kilojoules, the source unit ('watt-hour'), the target unit ('kilojoule'), the energy dimension label, and a precision note ('IEEE-754 double').
Example use cases
Battery capacity in kilojoules
“I have a battery rated at 500 watt-hours — can you tell me how many kilojoules that is?”
Solar panel output conversion
“My solar panel produced 2.75 watt-hours today; what's that in kilojoules?”
Appliance energy use in kJ
“A microwave used 0.083 watt-hours running for 30 seconds — convert that to kilojoules so I can log it in my energy audit.”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/watt-hour-to-kilojoule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, precision-documented (IEEE-754 double) watt-hour to kilojoule conversion via a simple GET request, especially within an automated agent workflow that already handles x402 micropayments. Suitable for physics, engineering, or energy-monitoring pipelines needing programmatic unit conversion without building the formula in-house.
Side effects
- Missing required 'value' query parameter returns an error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected by schema validation
- Non-numeric value for 'value' parameter causes a 400-class error
- Payment failure or insufficient USDC balance blocks the call
