Hurricane Basin Status Chain (NHC Official)
x402
Hurricane Basin Status Chain (NHC Official) is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).
Returns a 3-leg sequential chain of NHC-official hurricane data for one basin: genesis probability, active storm details, and official watches/warnings/landfall confirmations.

How this service works
[3-LEG] Hurricane chain, one basin (?entity=atlantic|epacific|cpacific): leading NHC official 2/7-day genesis probability (NHC-quoted, not our forecast) -> current active storms - category, wind, pressure, position -> realized official watches, warnings, landfall (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: NOAA NHC. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A 3-leg sequential chain response: Leg 1 quotes the current NHC official 2-day and 7-day tropical cyclone genesis probabilities for the requested basin. Leg 2 lists currently active named storms with their category, maximum sustained wind, minimum pressure, and current position. Leg 3 provides realized official watches, warnings, and landfall confirmation events. Confidence in the reading is indicated by how many legs return data. Returns 422 with no_charge if no data is available for the basin.
Example use cases
Atlantic hurricane season situational awareness
“What's the full NHC hurricane picture for the Atlantic right now? I need the genesis probabilities, any active storms with their category and pressure, and any official watches or warnings that have been issued.”
Eastern Pacific storm tracking for shipping
“Check the Eastern Pacific hurricane chain for me — are there any active storms, what's their current category and position, and have any warnings been issued that could affect shipping routes?”
Central Pacific landfall monitoring
“Is there anything active in the Central Pacific basin right now? Give me the NHC genesis odds, any storm details, and whether any landfall confirmations or warnings are in place.”

Endpoint
GEThttps://api.truthbear.co/gauge/hurricane-regionWhen to prefer
Choose this endpoint when you need official NHC-sourced hurricane basin status in a structured 3-leg chain format — genesis probability, active storm telemetry, and watch/warning/landfall confirmation — for one of the three supported basins (Atlantic, Eastern Pacific, Central Pacific). Prefer this over general weather APIs when you specifically need tropical cyclone genesis probability quoted directly from NHC, or when you need to confirm official watches and warnings rather than model forecasts. The no_charge 422 on no-data makes it cost-safe to poll during quiet seasons.
Side effects
- 422 no_charge returned when no data is available for the basin — agent is not billed
- Invalid entity value (not atlantic, epacific, or cpacific) results in an error
- Partial chain response if only some legs have data — confidence score reflects number of lit legs
- NHC data latency or outage may result in stale or missing leg data
- cpacific basin may have no active storms for long stretches, returning minimal data
