{"jsonrpc":"2.0","id":1,"method":"tools/list"}search_lei — Search the GLEIF LEI registry by legal entity name. Returns matched entities with their 20-character LEI, jurisdiction, status, and BIC/ISIN cross-references. Use the LEI to resolve canonical identity across SEC, OpenSanctions, and counterparty databases. Name matching is whole-token AND against the REGISTERED legal name, so abbreviations that do not literally appear ("Microsoft Corp", "Toyota Motor Corp") match nothing on their own; this tool automatically retries with legal-form suffixes dropped, with the words joined ("Exxon Mobil" -> "ExxonMobil"), and finally against GLEIF fuzzy autocomplete. The response always reports `match_mode` and `searched_as` so you can see which query actually produced the rows.get_lei — Fetch the full Level 1 LEI record for a legal entity. Returns legal name, registered address, headquarters address, entity category, legal form, registration authority, LEI registration status (ISSUED / LAPSED / RETIRED / ...), jurisdiction, parent LEI (if any), and timestamps. Accepts a company NAME as well as a 20-character LEI — a name is resolved against the registry here and the match is echoed back as resolved_from_name. Answers "is this company's LEI still active or has it lapsed" and "where is this entity registered".get_lei_relationships — Fetch Level 2 corporate hierarchy for an LEI: direct parent, ultimate parent, and direct children. Use to map ownership trees across multinational groups. Accepts a company NAME as well as an LEI.isin_to_lei — Resolve an ISIN (12-character international securities identifier, e.g. "CH0038863350" or "DE0007164600") to the LEGAL ENTITY that issued the security: its LEI, registered legal name, jurisdiction, and status, via the official GLEIF ISIN-to-LEI mapping. Answers "who issued this security" / "which company is behind ISIN X" for non-US as well as US securities. An ISIN identifies one security while the issuer typically has many — the response says what it resolved TO. A valid ISIN with no mapping yet is reported as unmapped (the mapping lags new issuance), distinct from an invalid ISIN.lei_to_isins — List ALL ISINs (securities) issued by a legal entity, from the official GLEIF ISIN-to-LEI mapping. Accepts a 20-character LEI or a company NAME (resolved automatically and echoed back). Answers "what securities has this company issued" / "all ISINs for Nestlé". Returns the full set — bonds, share lines, ADRs — not a single value; an entity that exists but has no mapped ISINs returns an empty set with that stated.bic_to_lei — Resolve a SWIFT/BIC bank identifier code (8 or 11 characters, e.g. "DEUTDEFF" or "DEUTDEFFXXX") to the bank's legal entity: LEI, registered legal name, jurisdiction, and status, via the official GLEIF BIC-to-LEI mapping. Answers "which legal entity is behind this BIC" / "LEI for SWIFT code X" for cross-border bank identity (KYC, counterparty due diligence, payments). A branch BIC that has no mapping of its own falls back to the head office (the trailing "XXX" form) and says so.lei_hierarchy_tree — Walk the FULL corporate ownership hierarchy for an entity in one call: the ancestor chain from the entity up to its ultimate parent, plus a multi-level tree of subsidiaries below it (breadth-first over GLEIF Level 2 direct-child records, depth-limited, depth stated in the response). Accepts a 20-character LEI or a company NAME. Answers "everything this group ultimately controls" / "full subsidiary tree of Deutsche Bank" / "who is at the top of this entity's ownership chain" — use get_lei_relationships instead when one hop (direct parent + direct children) is enough.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
