# AEO AI-Crawler Access Matrix

> AEO AI-Crawler Access Matrix is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Audits a website's robots.txt to report allowed, blocked, or unlisted status for 2026-cohort AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, etc.) with a composite score.

## Facts

- Endpoint: GET https://payai.agentstools.dev/aeo/crawlers
- Price: $0.005/call
- Payment: x402

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_u7kqBUJgzJXZ8yMkYUfgw

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 aeo-ai-crawler-access-matrix-44a86e3d
```

Example prompt: Can you check whether AI crawlers like GPTBot, ClaudeBot, and PerplexityBot are allowed or blocked on openai.com — and give me the overall AEO score?

## When to prefer this

Choose this endpoint when you need a structured, per-bot breakdown of AI crawler access from a single robots.txt fetch — especially when auditing for answer engine optimization (AEO) readiness, diagnosing missing AI-search visibility, or comparing competitor crawler policies. It covers the full 2026 AI-bot cohort in one call, making it faster than manually parsing robots.txt and more comprehensive than generic SEO crawl checkers that don't track LLM-specific bots.

## Known failure modes

- No robots.txt present — endpoint may return empty or default-permissive interpretation
- Invalid or unreachable URL/host — returns an error indicating the target could not be fetched
- Malformed domain input — rejected if neither url, host, nor domain resolves
- robots.txt too large or non-standard format — partial parse results may lower confidence in output

## How this service works

robots.txt AI-crawler access matrix: for the 2026 cohort of AI and answer-engine crawlers (GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, Claude-User, PerplexityBot, Google-Extended and more) reports allowed, blocked or unlisted per bot, whether the default rule blocks everything, declared sitemaps and a score. One network operation.

## Output

Returns per-bot access status (allowed, blocked, or unlisted) for the full 2026 cohort of AI and answer-engine crawlers (GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, Claude-User, PerplexityBot, Google-Extended, and more), a flag indicating whether a catch-all default rule blocks all crawlers, a list of declared sitemaps, and a composite AEO score summarizing overall AI crawler friendliness.
