x402
TruthBear Severe Convection & Hail Chain is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).
Returns a 3-leg sequential chain for a named convective region: SPC Day-1 outlook with CAPE/CIN/shear, current storm reports, and realized hail/wind damage confirmations.

How this service works
[3-LEG] Severe convection and hail chain, one convective region (?entity=tornado-alley-core): leading SPC Day-1 outlook with CAPE, CIN and shear - hours of lead -> current current storm reports -> realized hail and wind damage reports (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: NOAA SPC. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A JSON object representing three sequentially chained legs: (1) leading SPC Day-1 convective outlook including CAPE, CIN, and shear values; (2) current storm reports for the specified region; (3) realized hail and wind damage reports as confirmation. A confidence score reflects how many legs are currently 'lit' (1–3). Returns HTTP 422 with no_charge code if data is unavailable for the requested region, and the call is not billed.
Example use cases
Pre-storm hail risk check for insurers
“What's the current severe convection chain status for the Texas Panhandle hail corridor? I need the SPC outlook, active storm reports, and any confirmed hail damage coming through so far today.”
Operational farm field decision support
“Check the high-plains-hail-alley convection chain for me — are there any active storm reports and has hail damage been confirmed on the ground yet today?”
Real-time severe weather monitoring dashboard
“Get me the 3-leg severe weather chain for central-kansas — I want to know if the SPC Day-1 outlook is elevated, whether storm reports are coming in, and if any realized hail or wind damage has been confirmed.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/severe-convection-regionWhen to prefer
Choose this endpoint when you need a sequential, multi-leg confirmation chain for severe convective weather in a specific US region — not just a raw forecast, but a pipeline from leading SPC outlook signals through current storm activity to realized hail and wind damage confirmation. Preferred over generic weather APIs when you need NOAA SPC-sourced CAPE/CIN/shear data chained with ground-truth damage confirmation in one call. Best when operating in one of the 16 predefined monitored convective regions.
Side effects
- 422 no_charge: no data available for the specified entity — call is not billed
- Invalid entity ID returns error — use GET /gauge/catalog?signal_id=<signal_id> to list valid entities
- Payment failure via x402 prevents call completion
- Partial data: some legs may return null if SPC or storm report sources are unavailable
