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

Performs an AI-search visibility (AEO) audit of a website, computing a composite score 0-100 across six axes: answerability, structured data, AI-crawler access, crawlability, llms.txt readiness, and MCP well-known readiness, plus prioritized fixes.

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 agentstools-aeo-audit-885019c7
```

Example prompt: Run a full AEO audit on https://mybrand.com — I want to see the composite AI-visibility score, the breakdown across answerability, structured data, AI-crawler access, crawlability, llms.txt, and MCP well-known readiness, and a prioritized list of fixes.

## When to prefer this

Use this endpoint when you need a deterministic, multi-axis AEO/AI-visibility audit of a public website without relying on any LLM inference. Prefer it over generic SEO tools when the focus is specifically on answer engine optimization, AI-crawler access, llms.txt presence, and MCP well-known readiness.

## Known failure modes

- Invalid or unreachable URL returns an error or low-confidence result
- Private or localhost URLs may not be fetchable
- Sites blocking all crawlers may yield incomplete sub-scores
- Missing or malformed query parameters (no url/host/domain) returns a validation error
- Rate limiting or payment failure (402) if USDC credit is insufficient

## 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 0-100 with a rating (poor, fair, good, or excellent), sub-scores across six axes (answerability, structured data, AI-crawler access, crawlability, llms.txt readiness, MCP well-known readiness), and a prioritized list of actionable fixes. Results are deterministic and based on the site's own public surface.
