description: Eikon Data API limits (request frequency, data volume per call, concurrent sessions) were
  enforced through the local Eikon/Workspace desktop session rather than via documented HTTP rate-limit
  headers, and exact published numbers depended on the licensed entitlement. Eikon was withdrawn June
  30, 2025; equivalent throttling now lives inside LSEG Workspace.

notes: No public, single-page rate-limit reference; limits were enforced locally by the Eikon/Workspace
  session and tied to the user's contract entitlement.
