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 calories (IEEE-754 double precision), the source and target unit labels ('watt-hour' and 'calorie'), and the energy dimension label.
Example use cases
Fitness device energy comparison
“I'm building a nutrition tracker — can you tell me how many calories are in 75 watt-hours so I can compare battery consumption to food energy burned?”
Physics homework energy conversion
“My homework says a heater uses 2.5 watt-hours — how many calories does that equal?”
Solar panel output in dietary calories
“Our solar panel produced 500 watt-hours today. How many calories is that in energy terms?”

Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/units/energy/watt-hour-to-calorie?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, server-side watt-hour to calorie conversion with IEEE-754 double precision, especially within an automated agent workflow that already uses the x402 micropayment protocol. Prefer it over client-side calculations when auditability or a canonical numeric result is required.
Side effects
- Missing required 'value' query parameter returns an error
- Negative values are rejected (minimum is 0)
- Values exceeding 1e+100 are rejected
- Non-numeric input causes a validation error
- Payment failure (402) blocks the response if USDC payment is not settled
