Current position of any cataloged satellite by NORAD number (e.g. 25544=ISS) via fresh Celestrak elements + SGP4. Returns sub-point lat/lon/altitude + speed; pass observer lat/lon for azimuth/elevation/range look angles.

Observer-local sky almanac for a lat/lon + time (computed, no upstream): sun & moon rise/set + current alt/az, moon phase + illumination + next quarter, and all 7 naked-eye planets (alt/az, RA/dec, magnitude, above-horizon). Stargazing, astrophotography.

Synthesis — what is notable in YOUR sky right now (lat/lon): the live almanac (sun, moon phase, planets above your horizon), near-Earth asteroid close approaches this week, and the ISS (position + whether it is above your horizon now). One call, three sources, per-section found/error.

Synthesis — profile a confirmed exoplanetary system by host-star name (e.g. "TRAPPIST-1"). Groups the star's planets, summarizes the host star, and COMPUTES the habitable zone (inner/outer AU from stellar luminosity), flagging which planets fall in it.

Current NOAA space-weather snapshot: planetary Kp index, solar flux, geomagnetic storm scale, aurora viewing forecast.

Latest daily stock quote for a US-listed ticker (e.g. AAPL, MSFT, BRK.B): open/high/low/close, volume, VWAP, trade count, change and percent change vs the prior session, plus company name, exchange, security type, and market cap. NOTE: end-of-day / delayed data (response flags delayed=true) — for daily snapshots and post-close analysis, not real-time trading. Market data by Massive (formerly Polygon.io).

Astronomically compute sunrise, sunset, solar noon, and civil/nautical/astronomical twilights for a coord + date.

Validate an EU VAT number against the official VIES register in real time. Confirms current registration for intra-EU trade and, when the member state discloses it, returns the registered business name + address. Covers the 27 EU states (Greece as EL) plus Northern Ireland (XI); Great Britain (GB) is not in VIES. Pass vat (full identifier like DE811569869) OR country + number. Returns {valid, countryCode, vatNumber, name, address, requestDate, reason}.

NOAA tide predictions for the nearest tide station to a coordinate.

Resolve a coordinate to its IANA timezone, current UTC offset, local wall time, DST status, and short abbreviation. Polygon lookup against a CC0 timezone boundary index + runtime tzdata for current transition rules.

TLD registry + Public Suffix List intelligence. tld=io returns IANA root-zone metadata (type, managing organization, unicode form). domain=shop.example.co.uk runs the full PSL algorithm: effective public suffix, registrable domain, subdomain, matched rule, and whether the suffix is ICANN or private/corporate (github.io, s3.amazonaws.com). For cookie scoping, per-registrant rate limiting, URL dedup, and abuse analysis.

Open a live TLS connection to a host and return its certificate: protocol + cipher, chain validity, leaf subject + issuer, valid-from/to, days-until-expiry, serial, SHA-256 fingerprint, SANs, chain length. Active probe; SSRF-guarded. Cert-expiry monitoring, TLS audits.

Look up or search the US Harmonized Tariff Schedule (HTS / HS codes). Pass code for an exact HTS number (returns the line + 10-digit stat suffixes with duty rates), or query for free-text → ranked candidate HS codes by hierarchical heading. ~29.6k public-domain USITC lines. The deterministic backbone for tariff classification.

Transcribe an audio file URL to text (wav, mp3, m4a, ogg/opus, flac, webm; ≤15 MB, ≤15 minutes — split longer recordings). Returns punctuated transcript, confidence, duration, detected language, word-level timestamps, and (diarize=true) speaker-segmented utterances.

Daily Treasury Statement (DTS) operating cash balance — Treasury General Account at the Federal Reserve, plus tax-and-loan + Federal Reserve deposit accounts. Liquidity-tracking + macro signals.

US National Debt — daily Debt to the Penny via US Treasury Fiscal Data. Total public debt + held-by-public + intragovernmental holdings, every weekday since 1993.

Official US Treasury exchange rates (quarterly) — used by federal agencies for foreign-currency reporting. Pair with /api/fx/rates (ECB daily) for cross-validation.

Monthly Treasury Statement (MTS) — Table 4 federal receipts by source. Monthly + fiscal-year-to-date totals by classification (individual income tax, corporate income tax, social-insurance, excise, customs, estate-and-gift, misc).

Fetch a page and return its article content with clutter stripped (no nav, ads, footer, scripts). format: markdown (default), text, both (JSON), html (self-contained reader page), or pdf (typeset reading doc). html/pdf return raw bytes.

Discover the URLs a page or sitemap points at in a single fetch — entries from an XML sitemap/sitemap-index, or links from an HTML page (auto-detected). Resolved-absolute, deduped, http(s)-only. Stateless, no JS, NOT a recursive crawler — re-call on a child sitemap/page to go deeper. limit 1-2000 (default 200); sameHostOnly keeps same-host links.

Like url.clean but renders the page in a real headless browser (JS executed) — for client-rendered / SPA pages where a raw fetch sees an empty shell. Same formats (markdown/text/both/html/pdf). Tier 2 (~10× url.clean). Use url.clean for server-rendered pages.

Open Graph / Twitter Card metadata for a URL — title, description, image, site name.

Validate a US bank ABA routing number with the Federal Reserve weighted mod-10 (3-7-1) checksum, not just a regex. Returns valid, routingNumber, and routing-symbol district. Catches transposed digits in ACH/wire setup.

Validate up to 100 mixed identifiers in one deterministic call. Pass items=[{type,value}] with type one of iban, gtin, aba, lei, bic, gln, sscc, isin, cusip. Each result (in input order, with index + type) carries valid/reason plus the same type-specific fields the single endpoints return. One bad value or unsupported type degrades to that item only. Collapses a whole record of checksum checks into one round-trip.

Validate a SWIFT/BIC code (ISO 9362): 8 or 11 chars = institution + ISO country + location + optional branch, with the country checked against ISO 3166. Returns parsed parts. Structure only, not a directory lookup.

Validate a CUSIP (9-character US/Canada securities identifier) with its mod-10 weighted check digit. Returns valid + check digit. Deterministic security-master validation.

Validate a GS1 GLN (Global Location Number), 13 digits with the GS1 mod-10 check digit. GLNs identify trading parties + physical locations in CPG supply chains / EDI. Deterministic.

Validate a product barcode (GTIN-8/12/13/14, UPC-A, EAN-13, ISBN-10/13) with the GS1 mod-10 / ISBN mod-11 check digit. Returns valid, type, and the canonical GTIN-14 key for product-master dedup. Deterministic — no checksum math in the LLM.

Validate an IBAN (International Bank Account Number) with full ISO 13616 checks: country-specific length + ISO 7064 mod-97 checksum, not just regex. Returns valid flag, normalized + 4-char-grouped form, country, check digits, and BBAN. Deterministic, ~85 countries — validate AND canonicalize bank details in one call instead of doing checksum math in an LLM.

Validate an ISIN (ISO 6166 securities identifier): 2-letter country + 9-char NSIN + Luhn check digit. Returns valid, country, nsin, and the embedded CUSIP for US/CA issues. Catches transposed chars in security master data.

Validate a Legal Entity Identifier (LEI, ISO 17442) with the ISO 7064 mod-97-10 check digits. Returns valid, normalized LEI, and the issuing LOU prefix. Confirms a counterparty/vendor LEI is well-formed before GLEIF lookup.

Validate a GS1 SSCC (Serial Shipping Container Code), 18 digits with the GS1 mod-10 check digit. SSCCs identify logistic units (pallets/cases) — the key field in shipping/ASN (EDI 856). Deterministic.

Decode a 3-character World Manufacturer Identifier (WMI), the first 3 chars of a VIN, to manufacturer.

Paginated list of all NHTSA-registered vehicle manufacturers (vPIC).

List all models offered by a make in a given model year (vPIC).

Vehicle 360 by VIN — decodes the VIN (make/model/year/trim/engine, NHTSA vPIC) then returns THAT vehicle's open safety recalls and owner complaints, keyed to the decoded make/model/year. Used-car due diligence, fleet safety, insurance.

NHTSA vehicle recall lookup. Search by VIN (precise), or make/model/year, or NHTSA campaign ID. Returns recall ID, component, summary, consequence, remedy, dates.
