Features

One endpoint.
Everything your users need to know about the sky.

Our agentic AI pipeline orchestrates premium data sources and large language models into a single 2-second call. No glue code required.

01

Real-time weather

Premium forecast data with hourly resolution. Automatic metric-to-imperial conversion based on locale.

02

Air quality & pollen

US EPA AQI scale with six pollen types (grass, tree, weed, mold…) and per-type severity classification.

03

AI-powered summaries

Our proprietary LLM pipeline generates context-aware, sport-specific commentary. Falls back gracefully with zero downtime.

04

Smart clothing engine

Rule-based recommendations across 7 temperature ranges. Sport-specific gear. Automatic health alerts layered in.

05

Severe weather alerts

Government-issued alerts piped through in real time with automatic retry logic and exponential backoff.

06

Blazing fast

Parallel upstream calls, ~2s average response, stateless architecture. Horizontally scales to whatever you throw at it.

How it works

Three steps. One HTTP call.

You send coordinates. We orchestrate the data stack. You get a rich JSON payload that's ready to render.

STEP 01

Send a request

Any HTTP client works. Pass a latitude, longitude, datetime, and an optional sport hint.

fetch('/v1/weather', { method: 'POST', body: JSON.stringify({ lat: 40.71, lon: -74.00, datetime: '2026-04-20T18:00Z', sport: 'baseball' }) })
STEP 02

Our AI agents take over

A swarm of specialized AI agents fan out across premium data sources, reason about conditions in real time, and synthesize everything into a single coherent response.

✨ GenerateNatural language
STEP 03

Get a rich response

A single well-typed JSON object. Render it directly or compose it into your own UI.

{ "weather": {…}, "air_quality": {…}, "clothing": […], "ai_summary": "You'll be warm…" }

Frequently asked

Quick answers.

What data sources do you use? +

We aggregate multiple premium weather, air quality, and environmental data providers — curated for accuracy and coverage. Our agentic AI layer reasons across all signals and generates the natural-language summary. All requests fan out in parallel for speed.

How fast is the API? +

Median response time is ~2 seconds end-to-end, including the LLM generation step. p95 sits around 3.4s. If you skip the AI summary, typical responses are under 600ms.

Do I need my own weather data credentials? +

No. All data provider access is fully managed and included in every plan. Enterprise customers can optionally bring their own credentials if they have existing commercial arrangements.

What happens if one data source is down? +

We degrade gracefully. The response always returns with whatever data we successfully gathered, and a _partial flag tells you which fields were unavailable. Your UI never has to handle a hard failure.

Is there a rate limit? +

Rate limits scale with your plan. Free: 10 req/min. Personal: 60 req/min. Team: 600 req/min. Enterprise: unlimited, with custom burst allowances.

Can I use it for non-sports apps? +

Yes. The sport field is entirely optional. Without it, the AI summary becomes a general-purpose outdoor advisory. We have customers building event platforms, delivery logistics, and even solar-panel monitoring on top of the API.
