Refinitiv Eikon Rate Limits

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 Eikon was withdrawn June 30, 2025; equivalent throttling now lives inside LSEG Workspace.

Policies

Session-Tied Throttling
Eikon Data API calls were authenticated through an active Eikon/Workspace desktop session; throttling and concurrency caps were enforced by the local session and the user's licensed entitlement.
Product Withdrawal
Eikon was retired June 30, 2025. Active integrations should migrate to LSEG Workspace / LSEG Data Library, which carry their own contract-bound limits.
