Query by city name or lat/lon. Times in the location local timezone. Most complete weather data pe

Seattle weather forecast API: live temperature nowcast and daily high forecast for Seattle-Tacoma Intl (KSEA), with calibrated probability the temperature ends above/below any Fahrenheit strike. KSEA is the official settlement station for Kalshi KXHIGHTSEA daily high temperature prediction markets. Built for AI agents trading weather prediction markets or needing real-time weather data. $0.05 with

Weather forecast for a location (global, keyless): current conditions, an hourly series (up to 48h) and a daily summary (up to 10 days: min/max temp + condition), from met.no. Pass lat+lon, or a place name. For travel, logistics, events, energy. No API key.

Current space-weather conditions — normalized NOAA SWPC Kp, solar wind, magnetic field, and X-ray flux used for solar-flare monitoring, with observation times and freshness.

Real-time Seoul weather — temperature, sky, humidity, wind (KMA official data)

Current weather for any place on earth. Give a city name or a latitude/longitude pair; get temperature, conditions, wind and humidity.

Global weather forecast by latitude/longitude: up to 48 hours of temperature, humidity, wind, cloud cover and next-hour precipitation in UTC with explicit units and model update time. Forecasts, not live observations; missing fields are null and sparse periods are not interpolated. Based on MET Norway data (CC BY 4.0); outage cache is flagged stale.

Trend insights for a topic, based on real Wikipedia page-view volume and momentum. Premium tier adds relatedTrends: other Wikipedia article titles matching the same search terms (title-similarity, not a curated semantic-relevance ranking). Not literal search/social trend data — see the response's `source` field.

One combined reading for agent loops: AI provider health from public status pages, x402 facilitator reachability on the XRP Ledger and recent changes in our record. Returns storm (boolean), level, one reason, asOf and sources with timestamps. Additive measured fields: observed_payment_success (15m/…

A task marketplace for agents. POST {spec, reward_credits} escrows the reward and lists the task; GET lists open bounties, GET ?id=X reads one task (any state) incl. its full spec. Workers claim (/bounty/claim), submit results (/bounty/submit); the poster approves (/bounty/approve) and the worker is credited minus a 20% house fee. TO POST: hold reward_credits credits first (POST /credits/buy, $0.0

Verify a claim or fact check a statement against public web sources: send a question and up to 5 URLs, get cited evidence - passages that support, contradict or fail to settle it. Claim verification with a citation for every excerpt: source URL, retrieval time, content hash. Never charges when nothing is retrieved. Free to evaluate: the `sample` tool returns one real response at no cost, so you ca

Single models are everywhere. This is the disagreement between them: per hour a median with a p15/p85 band, the full min/max spread, how many models still carry that hour, an agreement score, rain probability derived from pooled ensemble members rather than one deterministic run, a frost assessment, and the official DWD warnings in force for the point.

Weather forecast and alerts: give a latitude and longitude anywhere in the world, get the 7-day forecast (temperature, rain, wind). US spots use the National Weather Service and include active weather alerts; elsewhere MET Norway.

Official US weather forecast from the National Weather Service (NOAA): multi-day and hourly periods for any US coordinates or street address. Temperature in Celsius and Fahrenheit, precipitation probability, wind speed and direction, and plain-language conditions. Authoritative government public-domain data, commercial use OK.

Geocoding & Weather weather: Coordinates or place name -> current conditions and 7-day daily forecast in metric and imperial units (Open-Meteo).

NASA/JPL Horizons ephemeris/physical (keyless). POST {command} (+ optional obj_data/make_ephem/ephem_type/center/start_time/stop_time/step_size/format). Unpaid empty → 402; after settle empty/invalid → 400 charged:false. Light adjacency: swpc-space-weather (space weather ≠ Horizons ephemeris).

NASA POWER daily point climate/solar (keyless). POST {latitude}/{longitude}/{start}/{end} (+ optional parameters/community/format). Unpaid empty → 402; after settle empty/invalid → 400 charged:false. Disclose adjacency: swpc-space-weather / climate-trace-emissions (space weather / GHG ≠ POWER point meteorology).

NOAA SWPC space-weather alerts / X-ray flares (keyless). POST {product} alerts|xray-flares-latest. Empty -> 400 not charged. New space-weather vertical — disclose NASA space adjacency lightly.

Aviation Weather Center METAR observations (keyless). POST {ids}/{icao?} required. Empty -> 400 not charged. nws-alerts / weather / air-quality adjacency disclosed.

Use before travel, logistics, field work, events or outdoor plans in the US, or to monitor severe weather: returns the currently active National Weather Service alerts (tornado/hurricane/flood/winter storm/heat warnings, watches and advisories) with event, severity, certainty, urgency, headline, affected areas, onset/expiry times, issuing office and a trimmed description and safety instruction (fu

Cross-platform arbitrage detection between Polymarket and Kalshi: matched markets, price spreads, fee-adjusted EV. Coverage: liquid Polymarket markets in politics/geopolitics/elections/tech/economy/finance; low-volume long-tail, sports, culture, and weather are not included.

Get one current weather snapshot for a city/locality name or exact coordinates. Returns the nearest NOAA/NWS station observation where available; otherwise returns the latest MET Norway model point, always labeled explicitly as observation or model with bounded SI fields and source provenance.

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. The 5 newest come back by default; detail=full adds the NWS narrative. Use when: Decide

Forward geocode a free-text address, place name, or city (e.g. "Tokyo, Japan") into geographic coordinates — latitude and longitude — plus its IANA timezone. Use this to convert a location description into coordinates for mapping, distance, or timezone-aware lookups, or as the first step before coordinate-based endpoints like weather forecasts.

Latest observed weather signal for one city — a single-signal SPOT snapshot (like a market-data quote). Flat $0.01, payable by a STOCK x402 client (no binding nonce). Never returns history or more than one signal. Uncharged on unknown-city / no-data-yet.

Queries current temperature, wind speed, and weather codes from the public Open-Meteo API.

Instant weather by city name — temperature, feels-like, humidity, wind speed, precipitation, and condition. Just pass a city name; geocoding, data fetching, and response structuring are handled in one call. Global coverage updated every 15 minutes. No API keys, no geocoding setup, no rate limits.
