Weather Intel API

National Weather Service data collapsed into single-call, agent-optimized JSON with activity recommendations and severity scoring.

GET /api/weather/forecast 3 sats

Get structured weather forecast for a location. Collapses the NWS multi-step lookup (points → gridpoints → forecast) into a single call.

Parameter	Type	Description
`latitude`	double	Latitude (-90 to 90)
`longitude`	double	Longitude (-180 to 180)

# Direct call (no L402)
curl "https://agent-commerce.store/api/weather/forecast?latitude=40.71&longitude=-74.00"

# Via L402 proxy (paid)
curl "https://api.lightningenable.com/l402/proxy/{proxyId}/forecast?latitude=40.71&longitude=-74.00"

Response includes outdoorSuitable (bool) and outdoorReason per forecast period.

GET /api/weather/alerts 2 sats

Get active weather alerts for a US state with severity scoring (0-100).

Parameter	Type	Description
`state`	string	2-letter US state code (e.g., NY, CA)

curl "https://agent-commerce.store/api/weather/alerts?state=TX"

GET /api/weather/conditions 2 sats

Get current weather conditions from nearest observation station.

Parameter	Type	Description
`latitude`	double	Latitude (-90 to 90)
`longitude`	double	Longitude (-180 to 180)

curl "https://agent-commerce.store/api/weather/conditions?latitude=40.71&longitude=-74.00"

Usage tips: US locations only. Use decimal coordinates (e.g., 40.7128, -74.0060 for NYC). The NWS API can intermittently return errors on certain grid points — retry if you get an error. Alerts require a 2-letter state code (NY, CA, TX). Test your coordinates free at agent-commerce.store/api/weather/forecast?latitude=...&longitude=... before using the paid L402 proxy.

Value-Add

Single-call interface (NWS requires 2-3 sequential API calls)
Activity recommendations per forecast period (outdoorSuitable, outdoorReason)
Severity scoring on alerts (0-100 composite score)
Structured JSON instead of GeoJSON
Temperature in both Fahrenheit and Celsius for conditions
Automatic server-side retry on NWS transient failures

Upstream Source

National Weather Service API — public domain, no API key required. NWS is known for intermittent 404 errors on the /points endpoint; we retry automatically.
