Weather & location

Historical weather and climate database. Access daily temperature highs, lows, total precipitation (rain/snow), wind speeds, and cloud conditions for any coordinates or city worldwide. Essential for geointelligence, climate modeling, historical records, and agricultural planning.

Get flight information by ident (designator, registration, or fa_flight_id)

Multi-day weather forecast for any city or lat/lon worldwide — up to 16 days of daily highs/lows, precipitation & probability, UV, sunrise/sunset, wind, and plain-language conditions, plus optional next-24h hourly. Give a city name (geocoded) or coordinates. No API key, metric or imperial. Pass params as query (GET) or a JSON body (POST).

Live weather + 3-day forecast for any city or lat/lon worldwide — temperature, feels-like, humidity, wind, precipitation, cloud cover, and a plain-language condition. Give a city name (geocoded for you) or coordinates. No API key, metric or imperial units. Pass params as query (GET) or a JSON body (POST).

Historical daily weather for any location and date range (up to 1 year): high/low temp, precipitation, wind, conditions. Open-Meteo archive, no key, global. Data from 1940 to 5 days ago.

Get Address Counterparties Data

Number of Active Addresses — The number of unique addresses active in the network as a sender or receiver. Data by Glassnode.

Forward-geocode a street address or place name (WORLDWIDE) to coordinates + parsed address components via OpenStreetMap Nominatim (public, keyless).

Multi-period weather forecast for a US location from api.weather.gov (NWS, public domain). Give latitude and longitude; returns the place plus upcoming forecast periods (temp, wind, conditions). US coverage only.

Current weather conditions for any location on Earth: temperature, feels-like, humidity, wind speed/direction/gusts, precipitation, cloud cover, pressure, and human-readable condition. Open-Meteo, no key, global.

IP geolocation: give an IPv4 or IPv6 address, get its country, region, city, continent and approximate coordinates.

MX/SPF/DMARC preflight; not mailbox verification. Base mainnet USDC

ENS and reverse name resolution across EVM chains: name and address pairs with resolution proofs. POST /v1/name with a {name} to resolve forward (or an address to reverse-resolve) and get the pair and source as one JSON object. Deterministic per block. Pay per request in USDC; no account, no API key.

NWS daily/period forecast (about 7 days, day and night periods) for a US point or grid. From the NWS (US and territories), cached and refreshed about every 3 hours; a location not yet cached answers 404, is not charged, and is queued.

Skim Signal: film incentives — new state film-incentive award rounds and allocations across California, New York, Georgia, New Mexico, and Texas as structured items: official California Film Commission and Texas Governor announcements plus incentive-focused press coverage per state, tagged with the state they cover. Optional ?states= filter. Refreshed on a 30-minute cycle.

Current weather and a 3-day forecast for any city or lat/lon - temperature, humidity, wind, conditions. No account, no API key. Try GET /weather/sample.

Get weather observations (METAR) for a specific airport

List Wirecutter review URLs from the public Wirecutter review sitemaps. Defaults to recommendation-like review pages.

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.

Current weather for any city. Pass ?city=London

Weather for any coordinate. Current (default): temperature (C), relative humidity (%), wind speed, weather code — real-time. Historical: add start_date & end_date (YYYY-MM-DD, up to 92 days per call, archive lags ~5 days) for hourly history — backtest weather-sensitive strategies (energy, agriculture, logistics). Inputs: lat, lon, start_date?, end_date?. Keyless (Open-Meteo).

Inspect one IP address for network ownership, location and abuse signals.

Computes mean NDVI and an ordinary least-squares daily NDVI trend, then applies yield = intercept + mean_coefficient×mean_NDVI + trend_coefficient×daily_trend. It does not derive NDVI from imagery, account for crop stage or weather, or provide an agronomically calibrated forecast unless the caller supplies valid coefficients.

Geo, ISP, VPN/proxy detection. Pay per call with USDC (x402) or credits - archtools.dev

Minneapolis rental license check — is this property licensed? Property due diligence agent for Minneapolis Minnesota (Hennepin) housing compliance open data. GET ?address= (street 1-120 chars) → compliance_verdict (licensed_clean|licensed_with_violations|unlicensed|condemned_or_boarded), rental license status/tier/units/expiration, violation cases, condemned/boarded. Live City JSON. Tenant screening, landlord DD, lending. Sample: /mn/property-check/sample.

Real-time earthquake feed. Recent seismic events from USGS with magnitude, location, depth, and tsunami flag, filterable by magnitude, time, and radius.

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.

Worldwide forward geocoding for agents. Convert an address, landmark, city, postcode, or place name into latitude and longitude with normalized address components and confidence metadata.

Fast deterministic check that a public URL is alive: HTTP status, redirects, content-type, size, and title. Built for agent workflows before paying for deeper crawls.

Retrieves a filtered list of supported assets with their metadata including address, symbol, name, decimals, and network information.
