概览

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.

Claude Authenticity Skill

Verify whether an API endpoint serves genuine Claude and optionally extract any injected system prompt.

No installation required beyond httpx. Copy the code blocks below directly into a single .py file and run — no openjudge, no cookbooks, no other setup.

pip install httpx

The 9 checks (mirrors claude-verify)

#	Check	Weight	Signal
1	Signature 长度	12	`signature` field in response (official API exclusive)
2	身份回答	12	Reply mentions `claude code` / `cli` / `command`
3	Thinking 输出	14	Extended-thinking block present
4	Thinking 身份	8	Thinking text references Claude Code / CLI
5	响应结构	14	`id` + `cache_creation` fields present
6	系统提示词	10	No prompt-injection signals (reverse check)
7	工具支持	12	Reply mentions `bash` / `file` / `read` / `write`
8	多轮对话	10	Identity keywords appear ≥ 2 times
9	Output Config	10	`cache_creation` or `service_tier` present

Score → verdict: ≥ 85 → genuine 正版 ✓ / 60–84 → suspected 疑似 ? / < 60 → likely_fake 非正版 ✗

Gather from user before running

Info	Required?	Notes
API endpoint	Yes	Native: `https://xxx/v1/messages` OpenAI-compat: `https://xxx/v1/chat/completions`
API key	Yes	The key to test
Model name(s)	Yes	One or more model IDs
API type	No	`anthropic` (default, always prefer) or `openai`
Extract prompt	No	Set `EXTRACT_PROMPT = True` to also attempt system prompt extraction

CRITICAL — always use api_type="anthropic". OpenAI-compatible format silently drops signature, thinking, and cache_creation, causing genuine Claude endpoints to score < 40. Only use openai if the endpoint rejects native-format requests entirely.

# Claude Authenticity Skill

Verify whether an API endpoint serves genuine Claude and optionally extract any
injected system prompt.

**No installation required beyond `httpx`.** Copy the code blocks below directly
into a single `.py` file and run — no openjudge, no cookbooks, no other setup.

```bash
pip install httpx
```

## The 9 checks (mirrors [claude-verify](https://github.com/molloryn/claude-verify))

| # | Check | Weight | Signal |
|---|-------|--------|--------|
| 1 | Signature 长度 | 12 | `signature` field in response (official API exclusive) |
| 2 | 身份回答 | 12 | Reply mentions `claude code` / `cli` / `command` |
| 3 | Thinking 输出 | 14 | Extended-thinking block present |
| 4 | Thinking 身份 | 8 | Thinking text references Claude Code / CLI |
| 5 | 响应结构 | 14 | `id` + `cache_creation` fields present |
| 6 | 系统提示词 | 10 | No prompt-injection signals (reverse check) |
| 7 | 工具支持 | 12 | Reply mentions `bash` / `file` / `read` / `write` |
| 8 | 多轮对话 | 10 | Identity keywords appear ≥ 2 times |
| 9 | Output Config | 10 | `cache_creation` or `service_tier` present |

**Score → verdict:** ≥ 85 → `genuine 正版 ✓` / 60–84 → `suspected 疑似 ?` / < 60 → `likely_fake 非正版 ✗`

## Gather from user before running

| Info | Required? | Notes |
|------|-----------|-------|
| API endpoint | Yes | Native: `https://xxx/v1/messages`  OpenAI-compat: `https://xxx/v1/chat/completions` |
| API key | Yes | The key to test |
| Model name(s) | Yes | One or more model IDs |
| API type | No | `anthropic` (default, **always prefer**) or `openai` |
| Extract prompt | No | Set `EXTRACT_PROMPT = True` to also attempt system prompt extraction |

**CRITICAL — always use `api_type="anthropic"`.**
OpenAI-compatible format silently drops `signature`, `thinking`, and `cache_creation`,
causing genuine Claude endpoints to score < 40. Only use `openai` if the endpoint
rejects native-format requests entirely.
