Current experimental legal API, semantic search and MCP support; source data described as OGL v3.0.
- UK Government — Lex API
Current experimental legal API, semantic search and MCP support; source data described as OGL v3.0.
- UK Government — Parlex catalogue entry
Parliamentary analysis is described as Parlex; the historical Lex drafting article is linked there.
- Liam Wilkinson — Hello, World
The author’s February 2026 account of his career, project contributions and site.
What this check doesn’t establish
- The old Lex drafting article is linked from the Parlex catalogue entry; these overlapping names do not establish a single uninterrupted project history.
- No API execution or deployment continuity was tested.
- Author contribution is self-reported.
Confidence applies to the scope above, not every claim made by the underlying source. How confidence works
- Kind
- software (own work)
The current Lex API documents semantic search and MCP access to legislation. The government catalogue separately describes parliamentary debate analysis as Parlex, and links the older “Improving Legislative Drafting with Lex” article from that entry. The naming history should not be treated as proof that the current API and every earlier drafting tool are identical.
The author’s introductory essay names both Lex and Parlex among projects he contributed to. The own-work role records that self-reported contribution, not sole authorship or current maintenance responsibility.
