What problem does it solve?

Detects the real backend origin of Claude Code proxy/relay services when users need to verify whether traffic is going to official Anthropic, AWS Bedrock (Kiro), or Google Vertex AI (Antigravity), and when proxies attempt to disguise their routing.

Core Features & Use Cases

  • Three-backend detection: Identifies Anthropic API, AWS Bedrock (Kiro), or Google Vertex AI (Antigravity) routing based on response fingerprints.
  • Mixed-model scanning: Detects when a single proxy routes different models to different backends.
  • Anti-spoofing evidence: Uses negative evidence for missing Anthropic-only fields to catch deep spoofing and distinguishes dynamic vs forged ratelimit behavior.
  • Practical outputs for review: Produces per-model verdicts with confidence, evidence chains, and fingerprint details you can manually audit.

Quick Start

Run the detector against your proxy endpoint by setting the base URL and API key in environment variables and then executing the provided Python script to generate a backend verdict report.
