How this service works
444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.
Output
Returns the converted energy value in the requested target unit, typically as a numeric result with unit label and the original input echoed back for verification.
Example use cases
Scientific report unit normalization
“I have energy readings in BTUs from a lab instrument — can you convert 12,500 BTUs into kilowatt-hours so I can include them in my report?”
Dietary calorie to joule conversion
“Convert 2,000 kilocalories into kilojoules for me — I need the energy value in SI units for a nutrition label.”
Electrical engineering unit check
“What is 0.75 megawatt-hours expressed in megajoules? I need to verify this for an electrical load calculation.”
Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/tools/convert/energyWhen to prefer
Choose this endpoint when you need a quick, programmatic, pay-per-call energy unit conversion without setting up a local conversion library. Useful for agents handling scientific, engineering, or utility data that require on-the-fly unit normalization across joules, BTUs, calories, watt-hours, and other energy units.
Side effects
- Invalid or unrecognized unit names return an error or empty result
- Missing 'query' field causes a 400 bad request
- Ambiguous query strings without clear source and target units may return incorrect conversions
- Network or server errors on the Vercel host return 5xx responses
- Malformed input values (non-numeric) may cause parsing failures
