claude-authenticity

separate

Detect whether an API endpoint is backed by genuine Claude (not a wrapper, proxy, or impersonator) using 9 weighted rule-based checks that mirror the claude-verify project. Also extracts injected system prompts from providers that override Claude's identity. Fully self-contained — copy the code below and run, no extra packages beyond httpx. Use when the user wants to verify a Claude API key or endpoint, check if a third-party Claude service is authentic, audit API providers for Claude authenticity, test multiple models in parallel, or discover what system prompt a provider has injected.

When to use

• verify a Claude API key or endpoint
• check if a third-party Claude service is authentic
• audit API providers for Claude authenticity
• test multiple models in parallel
• discover what system prompt a provider has injected
