How this service works
Truth Bear reports facts and their official sources — screening-grade, verifiable, not predictions or advice. Pay per call with USDC (x402) or a 30-day access pass by card / Apple Pay / Google Pay / PayPal.
Output
A JSON object containing the seasonal percentile for the current reading, the frequency of that reading historically, a full percentile table for context, and metadata describing the method and source used to compute the placement. Returns a 422 no_charge error (unbilled) when no data is available for the requested signal and entity.
Example use cases
River flood risk historical context
“For the hydrology.river-level signal at entity 07010000, what seasonal percentile is the current reading at, and how does that compare historically? Include the percentile table.”
Drought severity ranking for water manager
“I'm tracking a precipitation signal — can you tell me what percentile this month's current reading falls in compared to historical seasonal data for entity 07010000? I want to know how unusual it is.”
Environmental report seasonal benchmark
“Pull the historical placement stats for signal hydrology.river-level at entity 07010000 — I need the current seasonal percentile, frequency, and the method used so I can include it in our environmental status report.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/historyWhen to prefer
Choose this endpoint when you need to contextualize a current signal reading against its historical seasonal distribution — specifically to understand whether a reading is unusually high, low, or typical for the time of year. Prefer it over raw time-series exports (gauge/history-series) when you only need the current placement summary rather than the full historical dataset. Use it as an enrichment layer alongside live readings or calibrated index data (gauge/calibrated) to add statistical depth.
Side effects
- 422 no_charge: no historical data exists for the given signal_id and entity combination — not billed
- Missing required query parameter signal_id or entity returns validation error
- Invalid signal_id format (must follow genus.species convention) causes rejection
- Entity ID not recognized for the provided signal_id — returns empty or error
- Endpoint is descriptive only; asking for forecasts or advice will not yield meaningful results
