+ScopeBlind Integration for LiteLLM
+
+Device-level rate limiting for LLM proxy operators.
+Verifies DPoP proofs (RFC 9449) to bind requests to unique devices
+instead of IP addresses — survives proxy rotation, VPNs, and shared networks.
+
+Requires:
+    SCOPEBLIND_API_KEY  – your ScopeBlind API key (from scopeblind.com/t/<slug>)
+
+Optional:
+    SCOPEBLIND_ENDPOINT – verification endpoint (default: https://api.scopeblind.com)
+
+Usage (proxy config.yaml):
+    litellm_settings:
+      callbacks: ["scopeblind"]
+
+    environment_variables:
+      SCOPEBLIND_API_KEY: "sb_..."
+
+Or programmatically:
