Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone. One join that turns an IP into "who runs this network and where" -- the lookup network-forensics, abuse triage, and fraud agents otherwise stitch together from a geo API plus a separate BGP source. Composes geo IP data + RIPEstat (RIPE NCC, CC BY 4.0); the routing/holder block degrades independently, with per-source status returned. Distinct from net.asn (AS-number first) and geo.ip (geo only): this is IP-first and joins both.

HUD Income Limits (IL) for a US county or state — the program-eligibility thresholds for HUD assistance, derived from Area Median Family Income: extremely-low (30% AMI), very-low (50% AMI), and low (80% AMI) income limits for household sizes 1–8, plus the area median income. Look up by 5-digit county FIPS or by 2-letter state. Optional year (defaults to latest). The raw HUD il30/il50/il80 codes are reshaped into clear nested limits by household size.

Annual international merchandise-trade flows from UN Comtrade (HS classification). Pass reporter (the country whose trade you want; ISO-2/ISO-3 like 'US'/'USA', a UN M49 number, or 'World'), optional partner (counterparty; default World), year (YYYY), flow (export|import), and commodity: 'TOTAL' (all goods, default), a specific HS code ('27', '8703'), or 'AG2'/'AG4'/'AG6' for a top-commodity breakdown at the 2/4/6-digit level. Returns trade value (USD), net weight, quantity, and the HS commodity, sorted by value. Country names are resolved from Comtrade's own reference data.

Resolve a bank / financial institution across identifier systems. Give exactly one of bic (SWIFT/BIC), lei, or fdic_cert and get the others back: LEI, every ISO 9362 BIC the institution registers, the FDIC institution record (when matched), jurisdiction, and a canonical name. The BIC<->LEI bridge is authoritative and live from GLEIF (the LEI record carries the institution BIC list, CC0); anchoring on an FDIC certificate returns the FDIC BankFind record and best-effort name-matches it to a GLEIF LEI (flagged via bridge). There is no free FDIC-cert<->BIC table, so the FDIC<->GLEIF link is name-match only -- per-source status + bridge make any partial resolve explicit. Sources: GLEIF (CC0) + FDIC BankFind (US public domain).

Resolve a legal entity across identifier systems. Give exactly one of name, lei, cik, or ticker and get the others back: LEI (GLEIF), SEC CIK, ticker(s) with exchange, jurisdiction, and a canonical entity name. This is the COMPANY-ENTITY resolver: it joins the legal entity (LEI) to its SEC filer identity (CIK/ticker) and back. For SECURITIES (FIGI, ISIN, share-class identifiers) use finance.security-resolve instead -- this one deliberately stays at the legal-entity layer. Composes SEC company_tickers_exchange (public domain) + GLEIF (CC0). The SEC<->GLEIF link is by name-match when you anchor on ticker/cik (best-effort, flagged via bridge + leiName); a supplied LEI is authoritative. Per-source status is returned so a partial resolve is explicit. No CUSIP/SEDOL.

Cross-venue prediction-market keyword search across Polymarket, Kalshi, and Limitless Exchange in one call. Pass q (required); filter by status (open/closed) and cap per-venue with limit. Each hit is tagged with its venue and returns the question, live YES/NO price (0-1 implied probability), USD volume, close date, and the venue URL — for finding the same real-world question wherever it trades. Read-only, keyless.

A wallet's open Polymarket positions. Pass the wallet (proxy) address; cap with limit. Each position returns the market title + outcome, share size, average vs current price, initial vs current USD value, unrealized USD P&L and percent P&L, whether it's redeemable, and the conditionId/slug. For inspecting any trader's live book (e.g. a wallet from predict.leaderboard or predict.whales). Read-only from Polymarket's Data API.

Resolve a NUCC Health Care Provider Taxonomy code -- the specialty code returned by medical.npi and printed on every NPPES record -- into its human specialty: grouping (top level, e.g. "Allopathic & Osteopathic Physicians"), classification (e.g. "Anesthesiology"), specialization, the official display name, and the section (Individual vs Non-Individual). The decode step every claims, credentialing, and provider-directory agent needs to turn an opaque 10-char taxonomy code into a readable specialty. Data: NUCC code set (public domain), bundled and version-pinned. Note: the CMS Medicare 2-char physician-specialty crosswalk is published only as a PDF, so medicareSpecialty is returned null (DEFERRED) rather than guessed.

Real-time water data from USGS NWIS stream / river / groundwater gauges within a bounding box around lat/lon. Returns each site's latest reading per requested variable: streamflow (00060, ft³/s), gage height (00065, ft), water temperature (00010, °C), precipitation (00045, in), and others. Each reading: site code + name, lat/lon, variable name + description + unit, value (or null if no data / sentinel), qualifier codes (e.g., 'P' = provisional, 'A' = approved), observed timestamp. Free public-domain data from waterservices.usgs.gov.

Browse Polymarket events (an event groups related markets — e.g. an election, a tournament, a price ladder). Optional keyword q, closed filter, order (volume/volume24hr/liquidity), and limit/offset. Each event returns its title, tags, USD volume + 24h volume, liquidity, dates, and the nested markets with their outcomes + live outcome prices (implied probabilities) and CLOB token ids. Read-only mirror of Polymarket's Gamma events.

Cross-venue equivalent-market pairs for arbitrage / relative-value spotting. We fuzzy-match open Polymarket vs Kalshi markets by title-token overlap and return candidate pairs with both venues' YES prices and the implied-probability spread (Polymarket YES minus Kalshi YES). Tune with minScore (0-1 title-similarity floor) and limit. Heuristic — a high score is a strong candidate, not a guaranteed identical contract. Read-only, keyless. No public source maps these directly; the pairing is derived by 2s.io.

NFL players from balldontlie — search by name and page through results. Each player: id, name, position, height, weight, jersey number, college, experience, age, and current team. Cursor-paginated (pass meta.cursor as cursor to continue).

Resolve a 10-digit NPI to the provider identity plus a fully decoded specialty profile in one call: entity type, name/organization, status, the primary specialty (NUCC grouping + classification + display name), and every taxonomy on the record decoded the same way -- with primary flag, practice state, and license. Combines the NPPES lookup (medical.npi) with the NUCC specialty decode (medical.taxonomy-specialty) so a claims, credentialing, or referral agent gets "who is this NPI and what do they actually do" without a second call. Data: CMS NPPES + NUCC (US public domain). Note: the facility CCN (CMS Certification Number) requires a separate CMS enrollment crosswalk and is returned null (DEFERRED) rather than guessed.

HUD Fair Market Rents (FMR) for a US county or state — HUD’s annual gross-rent estimate (rent + utilities) by bedroom size (efficiency through 4-bedroom), the basis for Housing Choice Voucher payment standards and other HUD programs. Look up by 5-digit county FIPS (returns the county/metro rents, broken out per ZIP where HUD publishes Small Area FMRs) or by 2-letter state (returns every metro area + county). Optional year (defaults to latest). Source: HUD USER FMR API (US public domain).

NFL teams from balldontlie — all 32 franchises with id, full name, abbreviation, conference (AFC/NFC), division, and city. Pass an optional team id to fetch a single team.

Cross-walk a traded-good code across HS (6-digit international Harmonized System) <-> HTS (US 10-digit import) <-> Schedule B (US 10-digit export) <-> NAICS industry. Pass the system + code and get the shared HS6, the official description, the matching Schedule B and HTS national lines, the NAICS industry(ies), and the SITC code. The join an import/export, customs, or supply-chain agent needs to move between the export schedule, the import tariff schedule, the international HS level, and the industry that makes the good -- all keyed on the globally-harmonized HS6 bridge. Backed by bundled public-domain US Census Foreign Trade concordances (Schedule B + HTS, latest annual). For a 10-digit input the NAICS is narrowed to that exact national line; cross-schedule lines are surfaced via the shared HS6 and flagged in notes. Companion to trade.tariff (duty rates) and business.naics (industry detail).
