# Spoofed Crawler Evidence Packet Standard

> Spoofed Crawler Evidence Packet Standard 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).

Generates a deterministic, machine-verifiable evidence report packet for documenting and triaging AI crawler identity spoofing incidents (e.g. fake ClaudeBot, GPTBot, Bytespider, PerplexityBot).

## 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-crawler-evidence-packet-standard-36b6132d
```

Example prompt: I just caught a scanner pretending to be GPTBot on my site — can you generate a standardized evidence packet capturing the spoofing incident so I have a machine-verifiable report with TLS fingerprint mismatch, reverse DNS, and user-agent validity checks?

## When to prefer this

Choose this endpoint when you need a standardized, deterministic, machine-verifiable evidence schema for documenting AI crawler spoofing incidents — specifically when you want to capture forensic fields (TLS fingerprint, ASN, reverse DNS, user-agent validity, robots.txt path) in a structured format suitable for audit trails or security reporting. Prefer it over ad-hoc logging when you need interoperable, schema-conformant output that can be shared across teams or submitted to a facilitator.

## Known failure modes

- Missing or malformed required input fields returns a validation error
- Payment not completed results in 402 Payment Required response
- Invalid method (non-GET/HEAD/DELETE) returns 405 Method Not Allowed
- Service unavailable or handler error returns ok:false in result object
- Metadata-only call (meta=1) returns schema info without paid result

## How this service works

Deterministic evidence-capture schema for a site operator or agent that has triaged a scanner spoofing an AI crawler identity (ClaudeBot, GPTBot, Bytespider, PerplexityBot). Turns a suspicion into a machine-verifiable report packet. Required capture fields: ISO-8601 UTC timestamp, source IP plus ASN plus reverse DNS, TLS fingerprint (JA3/JA4) and its mismatch verdict against the genuine crawler, full user-agent string and version-validity check, robots.txt path actually requested versus the

## Output

A structured JSON evidence packet confirming the spoofing incident, including a service slug, ISO-8601 generatedAt timestamp, handler success indicator, and a payload containing captured forensic fields (IP, ASN, reverse DNS, TLS fingerprint mismatch verdict, user-agent validity, robots.txt path comparison) sufficient for machine-verifiable reporting.
