BOE Open Data

FreeSpain

Official open-data API of Spain's Boletín Oficial del Estado (BOE), the national gazette agency: consolidated national legislation (acts, decrees, with ELI identifiers and article-level text), Tribunal Constitucional rulings (resolved by case number, with ECLI citations), and binding administrative doctrine from the tax authority (DGT rulings), the Central Economic-Administrative Tribunal (TEAC criterios), and the data-protection authority (AEPD resolutions). Access is free and keyless directly from BOE's own API; an open-source MCP connector (es-eli-mcp) exposes it to Claude and other MCP clients with dedicated tools per source — consolidated-text retrieval for legislation, citation lookup for Tribunal Constitucional rulings, and full-text/date search for DGT and AEPD. It's an early-stage, single-maintainer project: TEAC search doesn't yet support text filtering, and BOE's own keyword search endpoint isn't currently reliable through this connector — legislation lookups work best by known identifier (ELI/BOE id) rather than full-text search for now.

Trifolia

FreemiumChile

Chilean legal AI covering case law (Supreme Court, Courts of Appeals, and civil/labor/family/criminal courts, via the Poder Judicial's jurisprudence search), legislation (LeyChile, including repealed norms), and doctrine (law-school and SciELO Chile sources) — plus administrative opinions from Contraloría, SII, CMF, the Competition Tribunal and other agencies that don't fit case law/legislation/doctrine cleanly. No public REST API; access is via the web app, a Word add-in, or an MCP connector listed in the Claude/ChatGPT directories (available on the free plan).
