Provided by Yuandian (元典)

Legal-data layer of Yuandian Open Platform (元典开放平台), the API/MCP arm of 华宇元典, a subsidiary of publicly listed Huayu Software (华宇软件). The platform's own homepage (live counters) states 183M+ judgment documents (~174M court judgments, ~9.18M procuratorate documents, 50,000 curated authoritative cases) and 6.22M+ laws and regulations at every level — the two categories this catalog covers, accessed through 9 of its 40 API endpoints (5 for laws/regulations, 4 for case documents). It also indexes 138M+ company records across a further 31 enterprise-compliance and securities-compliance endpoints (litigation exposure, securities filings), which sit outside case law/legislation/doctrine and aren't reflected in this entry's document count. Both the REST API and the MCP (5 servers: law, case, company, securities, hallucination-check) require a key; no public terms or pricing page was found.

Wenshucha (文书查)

FreemiumChina

160M+ Chinese court judgment records (1985–present) across criminal, civil, administrative, enforcement and state-compensation cases, from all court levels — case law only, no legislation or doctrine. By the vendor's own account, about 84% of records actually contain judgment text. REST API (search/detail/related/statutes/semantic/outcome-prediction endpoints) and an MCP server (search_judgments, get_judgment, verify_case_number, verify_quote) share the same quota: a public demo key gives 20 calls/day with no sign-up, a free tier (1,000 calls + 100 full texts/month) requires contacting the vendor via WeChat, and Pro is ¥99/month for 50,000 calls + 5,000 full texts. No public terms page was found.

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.
