# Spoofed AI Crawler Response Playbook

> Spoofed AI Crawler Response Playbook is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).

Returns a decision procedure for distinguishing genuine AI web crawlers (ClaudeBot, GPTBot, PerplexityBot) from mass scanners spoofing those user-agents, using IP registry checks, reverse-DNS, and TLS fingerprint validation.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability spoofed-ai-crawler-response-playbook-c928278d
```

Example prompt: I'm getting a lot of requests claiming to be ClaudeBot hitting my site — give me the step-by-step decision procedure to check whether each request is a genuine AI crawler or a scanner spoofing that user-agent, including the IP registry check and reverse-DNS verification steps.

## When to prefer this

Choose this endpoint when you need a structured, paid-for decision procedure specifically for distinguishing spoofed AI crawler user-agents from genuine bots, covering IP registry matching, reverse-DNS, and TLS fingerprint checks. Prefer it over generic bot-detection guides when you need an agent-consumable, prose-formatted playbook you can feed directly into an automated gateway decision or audit log.

## Known failure modes

- Missing or malformed input parameters may return an error or incomplete procedure
- Payment not settled results in a 402 response requiring x402 payment before content is returned
- Invalid topic override may fall back to default procedure or return an error
- LLM generation source may produce variable prose on repeated calls for the same topic
- Rate limiting or facilitator credit exhaustion blocks requests mid-session

## How this service works

Decision procedure for handling inbound crawler traffic that claims to be a known AI bot (ClaudeBot, GPTBot, PerplexityBot, etc.) when mass scanners are spoofing those user-agents. Inputs: claimed user-agent, source IP, target path sensitivity, content license flags. Checks run in order: 1) registry match, claimed agent must appear in the operator's published IP range list and the source IP must fall inside it; 2) reverse-DNS and TLS fingerprint consistency, a real crawler shows matching

## Output

A JSON object containing a prose decision procedure (120+ words) describing ordered verification steps for the claimed bot, the topic slug, ISO-8601 generation timestamp, the generation source (llm, reasoning, or deterministic), and a service slug confirming the playbook identity.
