Complete callable LaunchDarkly REST API suite pinned to the official OpenAPI document: 388 of 390 method/path operations. The two explicit exclusions are multipart CSV uploads for segment imports and team members, which await file_ref request-body support. The compatibility root keeps all 11 prior operation IDs and method/path routes while five dependency packs carry 377 additional operations. Stable routes send LD-API-Version 20240415; beta surfaces send beta. JSON int64 responses are parsed as exact decimal strings, and request bodies with unsafe nested int64 values use body_raw. The commercial base is an enrollment default; per-organization connections may use the documented EU or Federal origin. Reads are approval-free; mutations are grant-off and approval-gated, with destructive, administrative, flag-targeting, release, approval, experiment, and AgentControl changes requiring approval every run.
