How this service works
The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.
Output
Returns structured degree-day values (heating, cooling, growing) for the requested location and date range, derived from ERA5 reanalysis daily mean temperature data decoded from GRIB format. Suitable for energy demand estimation and crop growth modeling.
Example use cases
Example prompt
“What were the heating, cooling, and growing degree-days for Paris (48.85°N, 2.35°E) from January 1 to March 31, 2024?”

Endpoint
POSThttps://api.invoket.com/climate/degree-daysWhen to prefer
Choose this endpoint when you need historically grounded, high-quality degree-day computations (HDD, CDD, GDD) from ERA5 reanalysis data for any global location without managing API keys or subscriptions — ideal for energy audits, building performance modeling, agricultural planning, or climate analytics pipelines requiring pay-per-call simplicity.
Side effects
- Invalid or out-of-range coordinates return an error
- Date range outside ERA5 coverage (pre-1940) returns an error
- Malformed date format causes a 400 Bad Request
- Network or upstream ERA5 data unavailability may cause timeouts
- Payment not settled via x402 returns a 402 Payment Required
