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 share of the last 5 years spent in each official level band (as fractions), the percentile band boundaries, and the position of the current reading within those bands — all specific to the current day-of-year. Descriptive and approximate; not a forecast. Returns a 422 no_charge error with no billing if no data is available.
Example use cases
River flood risk contextualization
“For gauge station 07010000 using the hydrology.river-level signal, tell me what percentile band today's reading falls in and how much time over the last 5 years this station spent at that level for this day of year.”
ESG greenwash signal benchmarking
“Using the gauge strata add-on for the blackrock-art9-downgrade entity and the relevant ESG signal, show me the historical percentile distribution and where today's label-pressure reading ranks compared to the same day in prior years.”
DeFi utilization historical context
“Pull the statistical strata for the euler-v1 entity on the DeFi utilization signal — I want to see what percentile the current utilization sits at and how the last 5 years' readings are distributed across bands for today's date.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/strataWhen to prefer
Choose this endpoint when you need to contextualize a current sensor or signal reading against its own historical distribution for the same day-of-year — not for raw time series data (use gauge/history-series) or normalized cross-station comparison (use gauge/calibrated). Ideal for adding statistical context to environmental, financial, or operational dashboards where understanding 'is this reading unusual for this time of year?' matters.
Side effects
- 422 no_charge: no historical data available for the requested signal_id and entity combination — call is not billed
- Missing required query parameters signal_id or entity returns a 4xx validation error
- Invalid signal_id or entity values return an error; use /gauge/catalog to discover valid combinations
- Strata are approximate and stated as such; not suitable for precision-critical applications
