2026-07-18

  • Bilingual PL/EN pilot: this English section of the site, starting with the homepage and all 18 catalog detail pages, plus a language switcher in the accessibility bar.
  • A permanent accessibility bar at the top of every page: text size (A/A+/A++), a high-contrast mode, and a yellow mode.
  • The first two single-country entries: GENESIS-Online (Destatis, Germany) and Sirene API (INSEE, France) — the catalog grew from 16 to 18 entries, new jurisdiction values: DE, FR.
  • The About page and this changelog page; the catalog's data was made public on GitHub (bibi-bambi/otwarteapi-catalog) — new APIs and fixes can now be submitted via pull request.
  • An embeddable "listed in the catalog" badge (static SVG, no tracking).
  • A dedicated domain, otwarteapi.pl (previously otwarte-api.netlify.app).
  • The catalog was officially listed on llms-txt-hub.
  • Expanded with 4 EU institutions (ECB, Eurostat, EUR-Lex, data.europa.eu) and a new jurisdiction field (PL/EU) on every entry — the catalog grew from 12 to 16 entries.
  • Catalog launch: 12 Polish public APIs in the ai-catalog.json format, following the Agentic Resource Discovery (ARD) standard.

2026-07-19

  • 16 individual per-API pages, with a live "Try it" button for 8 APIs with open CORS (VAT Register, KRS, NBP, GUS BDL, dane.gov.pl, IMGW, Eurostat, data.europa.eu).
  • The szukaj_katalog_api MCP tool on the skanfirmy.pl/mcp server — an agent connected to skanfirmy.pl can now search this catalog directly.
  • Automatic monitoring of the catalog's link health; fixed 2 outdated documentation links (KRS, EUR-Lex).

2026-07-20

  • Three new single-country entries, each verified live (response + CORS header): ARES (Czech Republic, business registry), CBS StatLine Open Data (Netherlands, statistics) and INE Tempus3 (Spain, statistics) — the catalog grew from 18 to 21 entries, with new jurisdiction values: CZ, NL, ES.
  • All three new APIs have open CORS — they got a live "Try it" button just like the other 8, so now 11 of the catalog's 21 entries can be called directly from a browser.
