# AEO Audit – AI-Search Visibility Scorer

> AEO Audit – AI-Search Visibility Scorer is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Fetches a website's public surface and computes a composite AEO visibility score (0–100) across six axes—answerability, structured data, AI-crawler access, crawlability, llms.txt readiness, and MCP well-known readiness—plus a prioritized fix list.

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-audit-ai-search-visibility-scorer-7f956aad
```

Example prompt: Can you run an AEO audit on stripe.com and tell me its AI-search visibility score, how it rates across the six axes like answerability and llms.txt readiness, and what the top fixes are?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, structured AEO health check for any public website without relying on an LLM. It is ideal for developers or SEOs who want a reproducible, multi-axis score covering AI-era signals (llms.txt, MCP well-known, AI-crawler headers) that traditional SEO tools don't assess. Prefer it over generic SEO auditors when the specific concern is AI search engine and answer engine visibility.

## Known failure modes

- Target URL is unreachable or returns a non-2xx status — audit may be incomplete or fail
- Invalid or malformed URL/host/domain input — returns validation error
- Target blocks all crawlers including the auditor — AI-crawler access and crawlability scores may be artificially low
- Timeout fetching the target's public surface — partial results or error
- No input parameter provided (url, host, or domain all missing) — returns schema validation error

## How this service works

AI-search visibility (AEO) audit of a website for answer engines and agents. Fetches the target's own public surface and computes a composite visibility score 0-100 with a rating (poor, fair, good, excellent) across six axes: answerability, structured data, AI-crawler access, crawlability, llms.txt readiness and MCP well-known readiness, plus a prioritized list of fixes. Deterministic, no LLM. Visibility indicators, not a guarantee.

## Output

Returns a composite visibility score from 0 to 100 with a categorical rating (poor, fair, good, or excellent), plus individual sub-scores and ratings for six axes: answerability, structured data, AI-crawler access, crawlability, llms.txt readiness, and MCP well-known readiness. Also includes a prioritized list of actionable fixes. All results are deterministic and computed without an LLM.
