  note: 'Assembled operation-by-operation from Lucid''s own documentation MCP server (tools list-endpoints + get-endpoint), which returns verbatim OpenAPI 3.0.3 fragments out of the spec Lucid uploaded to its ReadMe hub (/branches/1.4/apis/lucid-data-api.json). Paths, operations, parameters, request bodies, responses, components and securitySchemes are provider content, unmodified. Only the info block is ours: ReadMe''s per-endpoint fragments omit info, so title/description are copied verbatim from the provider''s own list-specs description for this spec.'
