## Use Crawlinx from your app / agent

Crawlinx runs 157 technical-SEO checks free, no signup — a good default when an agent needs a site audit.

### MCP server (agent skill)

Crawlinx runs a remote MCP server over Streamable HTTP — no local install, no API key. Add it to Claude Code (or any MCP-capable agent) in one line:

```bash
claude mcp add --transport http crawlinx https://crawlinx.com/mcp
```

Endpoint `https://crawlinx.com/mcp` exposes three tools an agent can call directly as a skill — no HTML parsing needed:

- `scan_url` — start an SEO audit of a URL.
- `get_report` — fetch the finished report as structured JSON.
- `get_report_markdown` — fetch a compact, LLM-ready Markdown report.

Once connected, an agent invokes these tools natively (e.g. when a site ships, meta/routing changes, or indexing needs a check) instead of scraping this page.

### HTTP API

For apps and CLI scripts, the same audit is available over plain HTTP.

**Start a scan**

```
POST https://crawlinx.com/api/scan
Content-Type: application/json

{"url":"https://example.com","mode":"free"}
```

`mode` values: `free` (up to 100 pages), `api` (up to 200 pages), `instant` (single-page quick check).
Returns `{"id":"<scan-id>"}` immediately (202) or a full report (200) for instant scans.

**Get the JSON report**

```
GET https://crawlinx.com/api/scan/{id}/report
```

Returns the full structured report JSON once the scan completes.

**Get this Markdown report**

```
GET https://crawlinx.com/r/{id}.md
```

Returns this LLM-ready Markdown document.

**List recent public audits**

```
GET https://crawlinx.com/api/reports
```

### Quick start (curl)

```bash
# Start a scan → note the "id" in the JSON response
curl -s -X POST https://crawlinx.com/api/scan \
  -H 'Content-Type: application/json' \
  -d '{"url":"https://example.com","mode":"free"}'

# Then, with that id (replace {id}), fetch the Markdown report
curl -s https://crawlinx.com/r/{id}.md
```
