Filtering tested

JSON:API filters filter[field]=value. Several values with a comma (filter[entity.legalAddress.country]=NL,BE), exclude with ! (filter[registration.status]=!ISSUED), dates with > or >= (=>2025-01-01) and a range with .. (2025-01-01..2025-12-31), * as wildcard in names (ING*). Use curl -g, otherwise the brackets trip it up.

Parameters 6

Fields of a LEI record (attributes, selection) 14

Limits and pitfalls

• page[size] at most 200 and page numbering at most 10,000 records deep; beyond that cursor paging (page[cursor]=*). No rate limit headers seen. tested
• Filter on legal form with filter[entity.legalForm]=54M6 (164,791 Dutch private companies). filter[entity.legalForm.id] returns "Filter should contain only allowed values", as does entity.legalAddress.city (use entity.addresses.city). tested
• > and >= gave the same count for dates (37,749 Dutch LEIs from 2025). Counting per year works directly with a range: 2025-01-01..2025-12-31 gave 18,246. tested
• entity-legal-forms ignored filter[country]=NL (all 3,599 legal forms came back). Fetch a code directly or filter on countryCode yourself. tested
• The API follows the golden copy, published three times a day (00, 08, 16 UTC); meta.goldenCopy.publishDate tells which. The API ran one publication behind (08:00 while 16:00 was out). The full register: goldencopy.gleif.org/api/v2/golden-copies/publishes/latest (CSV zip 481 MB, 3,464,825 records). tested
• LAPSED means the LEI wasn't renewed, not that the company is gone. For the company, look at entity.status. experience
• api.gleif.org's robots.txt allows everything; goldencopy.gleif.org/robots.txt returned 403 (the API there works). tested
