How this service works
Add-on, precipitation for one location: daily rainfall plus 30-day accumulated wet-dry drought context from ERA5. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. Every record carries an offline-recomputable record_hash. $0.0050 per call.
Output
A JSON object containing daily rainfall figures and 30-day accumulated precipitation with wet-dry drought context derived from ERA5 reanalysis data, plus an offline-recomputable record_hash for data integrity verification. Returns a 422 no_charge error if no data is available for the location, and the call is not billed in that case.
Example use cases
Drought risk assessment for agriculture
“Pull the precipitation and 30-day accumulated wet-dry context for us-fresno so I can assess current drought conditions for the region.”
Urban flooding baseline check
“Get me the daily rainfall and 30-day precipitation context for us-stlouis — I need to understand the recent wet conditions before our infrastructure review.”
Audit-ready climate data retrieval
“Fetch the precipitation record for us-phoenix including the record hash so I can verify the data integrity in my report.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/precipWhen to prefer
Choose this endpoint when you need descriptive historical precipitation data (daily rainfall plus 30-day accumulated context) for a specific US location grounded in ERA5 reanalysis, with built-in audit trails via record_hash. Prefer it over forecast APIs when you want observed actuals with drought context rather than predictions, and over generic weather APIs when data verifiability and non-billing on missing data are important.
Side effects
- 422 no_charge: no data available for the requested location — call is not billed
- Invalid location ID: location not in accepted values list — check /gauge/preview for full list
- Network timeout or service unavailability
- Missing required 'loc' query parameter returns a validation error
