Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tomorrow: open an issue to ask a question, or submit a pull request to add artifacts.

features:
- name: 60+ Data Layers
  description: Core weather plus air quality (EPA/MEP indices, particulates, pollutants), pollen (tree species, grass, weed),
    fire (FWI), solar (GHI/DIF/DIR), lightning, soil moisture/temperature, marine swell and wave, aviation ceiling/visibility,
    and road conditions.
- name: Forecast Timelines
  description: Single endpoint returns minutely (1m/5m/15m/30m), hourly (1h), daily (1d) and current timesteps for any combination
    of fields. Up to 14 days out on paid plans, 5 days on Free.
- name: Historical Data
  description: Up to 20 years of historical observations for the same field universe as the forecast, retrievable by point
    or polygon.
- name: Climate Normals
  description: 30-year climate normals (monthly averages) for any location, useful for anomaly detection and climate-trend
    reporting.
- name: Weather on Routes
  description: POST a polyline or list of waypoints and receive weather along the route at each segment with arrival-time
    interpolation.
- name: Map Tiles
  description: Raster tile endpoint `/map/tile/{z}/{x}/{y}/{field}/{timeFormat}` for Mapbox, Google Maps, Leaflet, OpenLayers,
    Cesium overlays.
- name: Custom Insights and Events
  description: Define threshold rules (e.g. windSpeed > 15 m/s AND precipitationProbability > 50%) against any field, then
    poll the Events endpoint for matches at a location or buffer.
- name: Alerts with Webhooks
  description: Persistent alert resources linked to one or more locations; activations fire to a webhook destination so downstream
    systems can react in real time.
- name: Locations Management
  description: CRUD on point, polygon, and polyline locations with tag-based grouping, so monitored assets can be addressed
    by ID instead of repeated geometry.
use_cases:
- name: Aviation Operations
  description: Airlines use ceiling, visibility, wind shear, and storm cells along the route to make ground-stop, diversion,
    and de-icing decisions.
- name: Logistics and Routing
  description: Trucking, last-mile delivery, and rail use route-weather and lightning tracking to reroute shipments and reschedule
    outdoor crews.
- name: Energy and Utilities
  description: Wind, solar (GHI/DIF/DIR), and lightning data feed renewable forecasting, grid load planning, and outage prediction.
- name: Agriculture
  description: Soil moisture, soil temperature, evapotranspiration, and growing-degree days drive irrigation, planting, and
    spray-window decisions.
- name: Insurance Underwriting and Claims
  description: Historical hail, wind, and flood data inform underwriting; real-time hail and lightning detection accelerates
    claims triage.
- name: Sports and Live Events
  description: Stadium operators monitor lightning radius and precipitation probability to call delays and protect spectators.
- name: Public Safety and Government
  description: Fire weather (FWI), flood indices, and air-quality (EPA AQI) feed municipal alerting and emergency-management
    workflows.
- name: Retail and CPG
  description: Demand forecasting models use temperature anomalies and weekly weather patterns to plan inventory and promotions.
- name: Maritime and Offshore
  description: Wave height, swell direction, and wind data drive routing, port operations, and offshore platform safety windows.
integrations:
- name: Mapbox
  description: Vector and raster basemaps overlaid with Tomorrow.io map tiles.
- name: Google Maps
  description: JavaScript Maps API overlay support.
- name: Leaflet
  description: Open-source web map tile overlay.
- name: OpenLayers
  description: GIS-grade web map library tile overlay.
- name: Cesium
  description: 3D globe / aviation tile overlay.
- name: Postman
  description: Official Tomorrow.io Postman collection.
