Weather & location

Turn an address into coordinates: BAN for France (INSEE code, score), OpenStreetMap elsewhere. Address to coordinates: for France the official BAN registry (house number, street, postcode, city, INSEE code, match score), elsewhere OpenStreetMap Nominatim. Query: ?q=8 rue de la Paix Paris&country=fr&limit=1

ENS name resolution in both directions: an .eth name to its address, or an address to its primary ENS name, with the avatar when set. Query: ?name=vitalik.eth or ?address=0xd8dA…

Get ETH, USDC and up to ten ERC-20 balances of one address in a single call, human-readable. ETH plus USDC plus up to ten ERC-20 balances of one address in a single call, decimals resolved, amounts human-readable. Base mainnet. Query: ?address=0x…&tokens=0x…,0x…

Find the MCP server or API for a job: 37,000+ MCP servers and 2,500+ APIs, refreshed hourly, plus measured status for Arc agents. Which MCP server or API does this? Pass ?q=weather forecast and get matches from the official MCP registry (37,000+ servers, CC0) and the APIs.guru OpenAPI directory (2,500+ APIs, CC0), refreshed every hour: how to connect (remote URL or package), description, repository, docs and OpenAPI spec, last-updated date with a flag for entries untouched for a year.

Weather forecast API: current conditions (temperature, feels-like, humidity, wind, weather code) plus a 3-day daily forecast (highs, lows, precipitation probability) for any latitude/longitude worldwide, as structured JSON. Use for travel planning, logistics, event scheduling, and assistant agents. Cached 10 minutes.

Current time API: the time right now in any IANA timezone (America/Chicago, Asia/Tokyo...) — local ISO timestamp, UTC ISO, unix epoch, human-readable string, and day of week. The sanity check every scheduling, logging, and coordination agent needs. Deterministic and instant.

Great-circle distance (km and miles) between two IP addresses, with each endpoint's city/country/lat/lng.

Postal/ZIP code lookup: city, state, coordinates (60+ countries) — Genesis402 / UnyKorn Operator Network

Total precipitation in the last 48 hours for the given location(s). | ERROR: Unable to calculate price.

Real-time and forecast air quality index (AQI) and particulate matter database. Retrieves PM2.5, PM10, ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), US AQI scale labels, and European AQI parameters for any location globally. Crucial for smart city analytics, health monitoring, outdoor event planning, and environmental geointelligence.

Resolves an ENS name to its address, or an address back to its primary ENS name, reading Ethereum mainnet directly. Names are what humans paste and addresses are what chains need.

Verify OpenAPI/Swagger document reachability, parseability, operations/auth/servers. Base mainnet USDC

Everything an agent needs to plan a trip to one country, in ONE call: visa requirements, customs duty-free allowances, tipping customs, power plugs and voltage, emergency numbers, tap water safety, SIM/eSIM options, public holidays during the stay, currency and payment culture, tourist taxes, driving side and IDP rules. 195 countries, government-sourced. Cheaper than 15 single calls. Example: /api/v1/kit/travel/JP

Retrieve flight-level trip details and booking links for a Seats.aero availability ID.

Astronomical solar calculator and solar radiation forecast database. Returns highly accurate daily solar cycles: sunrise/sunset times, astronomical/civil/nautical twilights, precise solar noon, day length, maximum UV index, and shortwave solar radiation levels (MJ/m²) for any location globally. Crucial for solar panel yield forecasting, photography timing, agriculture, and outdoor wellness tracking.

Read the native ETH balance of an address on Base. POST {"address":"0x..."} and receive the balance in wei and in ether. Live chain state read directly from a node, with no indexer lag and no API key.

Before your agent plans across a whole network — fleet routing, multi-site operations, portfolio hedging: 2 m temperature, precipitation and 10 m wind forecasts for up to 500 point + lead-time queries in one call, from the deterministic NOAA GFS run (~16 days). Each query takes lat+lon or a city name plus an optional lead selector (omitted, it defaults to the current analysis time); an uncovered item is flagged via per-item coverage instead of failing the batch.

Forward liquidation cluster map + recent prints for all 17 crypto assets. Part A: estimated liq price levels for 5x/10x/25x/50x leverage bands, modeled from open interest and mark price — no new upstream source. Part B: real liquidation prints from OKX public API (no auth). Returns cluster map, nearest_long/short clusters, squeeze_bias, and honest disclaimers. Supports BTC/ETH/SOL/BNB/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/TRX/BCH/ATOM/NEAR/APT/HYPE-USD. Pay-per-call via x402.

Current U.S. EPA Air Quality Index (AQI) and pollution levels for a specific location, given latitude/longitude — use to check smog, air pollution, or whether it's safe to be outside. Sourced from the EPA AirNow program (federal/state/local/tribal agencies); covers the US, Canada, and Mexico only. Data is preliminary and unvalidated per EPA data use guidelines — not for regulatory use.

Verdix deep ($0.50): call before large or first-time payments to an EVM address on Base when your policy asks for the top tier. Same full check set as standard: sanctions, scam/phishing lists, address poisoning, contract/deployer signals, on-chain behaviour. Returns safe/caution/danger with reasons.

Use when enriching a list of Dutch addresses (up to 10 per call, 0.0015 USDC each): official BAG address and coordinates, CBS neighbourhood, liveability percentile, crime per 1,000 residents vs national, average home value and optionally the energy label. Unfound addresses are flagged, not charged extra.

Use when the user is choosing between 2 to 5 Dutch addresses: side-by-side liveability, crime, home values, floor area, year built, noise, air quality, ground height and distances to station, supermarket, school and GP, with the best address per metric and the full report for each. Input: addresses separated by ';'.

Wallet risk score 0-100 with component breakdown for an EVM address.

List a website's pages from any URL on it: reads robots.txt and XML sitemaps (indexes and .xml.gz included), or the home page's links when there is no sitemap. Returns URLs with last-modified dates; filter by search words or path prefix, up to 1,000 URLs. Find pricing, docs, blog or careers pages before scraping them. Not charged when nothing is found. No account or API key. $0.002 USDC per call.

List the daylight-saving transitions for an IANA time zone over a date range: the exact instant of each shift, the offset before and after, and whether local clocks jump forward or back. Returns the current offset and DST state, and the next transition from a given instant. Zones without DST return an empty transition list rather than an error.

Scan text for personal data: email, phone, national id, bank card, IBAN, crypto address, IP address, passport. COMMIT when nothing matches. NO_COMMIT on any finding. POST JSON {"response","agent_id"}.
