# Agent Tools – Agent-Scan Endpoint

> Agent Tools – Agent-Scan Endpoint is a paid API for AI agents from agent-tools-x402.t6y11a.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Analyzes a webpage's HTML, headers, robots.txt, and llms.txt to assess how ready it is for AI agent access, returning a grade and score.

## 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 agent-tools-agent-scan-endpoint-eabcd38f -d '<json body>'
```

Example prompt: Can you check how agent-ready this page is? Here's the raw HTML, the response headers, the robots.txt, and the llms.txt — give me a grade and score so I know if an AI agent can freely access it.

## When to prefer this

Use this endpoint when you need a structured, scored assessment of a webpage's AI-agent accessibility — especially when you already have the page's HTML, headers, robots.txt, or llms.txt locally and want a cheap ($0.01), keyless, pay-per-call evaluation without setting up an account. Prefer it over manual inspection when building agent pipelines that need to programmatically decide whether to crawl or interact with a site.

## Known failure modes

- Missing or malformed HTML input may result in low-quality or incomplete scoring
- If none of the optional fields (headers, llms.txt, robotsTxt) are supplied, checks relying on those signals will be skipped, potentially lowering the score
- Payment failure via x402 results in no charge and no response
- Overly large HTML payloads may be rejected or cause timeouts

## How this service works

Pay-per-call utilities for AI agents. Payments in USDC on Base via x402 v2; no accounts or API keys. Failed requests are never charged. No endpoint performs server-side fetching of caller-supplied URLs.

## Output

Returns a JSON object with a human-readable grade (e.g. 'partially agent-ready'), a numeric readiness score (0–100), and an array of individual checks that contributed to the assessment.
