# AIScan Agent Files Checker

> AIScan Agent Files Checker is a paid API for AI agents from api.getaiscan.app, paid per call via x402, $0.07/call, status unknown (last checked 2026-09-15).

Checks a website's agent-related files (e.g. llms.txt, agents.json, MCP manifest) to assess its MCP Readiness and agent discoverability

## 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 aiscan-agent-files-checker-78da46cf -d '<json body>'
```

Example prompt: Can you check whether https://stripe.com has the right agent files set up — like llms.txt or an MCP manifest — so I know if it's ready for AI agent discovery?

## When to prefer this

Use this endpoint when you specifically need to check whether a website has published agent-discovery files such as llms.txt, agents.json, or MCP manifests — i.e. its 'MCP Readiness' sub-score. It is one focused check within the broader AIScan suite, ideal when you only need the agent file presence result rather than a full multi-score AI visibility audit.

## Known failure modes

- Invalid or malformed URL returns validation error
- Target website is unreachable or returns 5xx — scan may fail or return incomplete result
- Website blocks crawlers and agent file fetches cannot complete
- Response schema is minimal and may not include detailed file-level breakdown beyond the capability string

## How this service works

AIScan audits any website for AI visibility in 60 seconds. 4 scores: AEO, GEO, Agent Readiness, MCP Readiness. Plus Brand Visibility: how often AI actually names your brand. The only scanner with MCP Readiness.

## Output

Returns the capability that was executed along with the analyzed site URL and payment settlement info; the core result indicates whether agent-related files (e.g. llms.txt, MCP manifest) were found on the target website
