Battle Net Rate Limits

Battle.net Developer APIs enforce two simultaneous limits per OAuth client (Client ID) — 100 requests per second and 36,000 requests per hour — across all regional API hosts (US/EU/KR/TW). Limits are not raised via a paid plan; applications expecting heavier load must contact Blizzard Developer Relations for partner-tier access.

Policies

Backoff Strategy
Use exponential backoff with jitter on 429 responses. Spread workload across the per-second window rather than bursting.
OAuth Client Scoping
Limits are tracked per Client ID, not per access token. Issuing additional tokens against the same client does not raise the ceiling.
Regional Hosts
us.api.blizzard.com / eu.api.blizzard.com / kr.api.blizzard.com / tw.api.blizzard.com share a single per-client quota.
Partner Access
Higher limits require a partner agreement with Blizzard Developer Relations; there is no self-serve paid tier.
