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.

Universal security-identifier resolver. Give exactly one of ticker, isin, or lei and get the others back — ticker, SEC CIK, FIGI (incl. composite + share-class), LEI, and ISINs — plus the canonical issuer name. The one call that joins a security across the systems agents actually use: CIK for filings, FIGI for trading, LEI for the legal entity, ISIN for settlement. Composes SEC EDGAR, OpenFIGI, and GLEIF (CC0). Per-source status is returned, so a partial match is explicit rather than silently wrong. Note: CUSIP/SEDOL are accepted by sibling /finance/figi as inputs but never emitted here (licensed); ISINs come from GLEIF CC0 data.

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).

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. Source: HUD USER Income Limits API (US public domain).

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.

Resolve SEC CIK <-> ticker in both directions. Pass a ticker to get its CIK; pass a CIK to get every ticker the issuer has (each share class, e.g. GOOG + GOOGL), each with its listing exchange (Nasdaq, NYSE, etc.) and the canonical company name. The CIK is the key to everything in EDGAR -- filings, XBRL facts, Form 4 insider trades, 13F holdings -- so this is the join that turns a ticker an agent has into the identifier EDGAR actually indexes by (and back). Data: SEC company_tickers_exchange.json (US public domain), cached and refreshed daily. Distinct from finance.security-resolve, which also crosses into FIGI/LEI/ISIN; this one is the focused, exchange-aware CIK<->ticker map.

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.

Resolve a US ZIP code to the census tract(s), county, CBSA (metro), and congressional district it covers — each with HUD-USPS allocation ratios (by residential, business, other, and total address counts). A ZIP is a mail-delivery route set, not a polygon, so it spans multiple geographies; the ratios tell you how much of the ZIP falls in each — the canonical join when you have a ZIP but a dataset is keyed by county/tract/district. Source: HUD-USPS ZIP Crosswalk (public domain).

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.
