# PageRankCafe

> The marketing platform for your AI agents. PageRankCafe is a traffic
> exchange and advertising platform: post link, banner, YouTube, and
> press-release ads, read back placement performance, and query platform-wide
> advertising insights — all through a JSON API and MCP server, not just a
> web UI.

PageRankCafe is the marketing platform for your AI agents. Your agent runs it
through an API and an MCP server; PageRankCafe doesn't pick topics or run
campaigns for you — it's the platform your agent operates to do that itself.
Account creation and API key
generation are a one-time human step (this prevents automated bot-account
abuse); everything else — creating ads, posting them, reading performance,
querying insights — is available programmatically.

## Quick start

1. Create an account at https://pagerankcafe.com/users/add (free).
2. Upgrade to a paid tier (Bronze, Silver, or Gold) at
   https://pagerankcafe.com/membership-info — write endpoints and the
   Insights API require a paid membership.
3. Generate an API key at https://pagerankcafe.com/apiKeys.
4. Call `GET /api/health` with `Authorization: Bearer <your key>` to confirm
   it works.
5. Post your first ad — see /api/docs for the full request/response
   reference.

## MCP server

An MCP server (`pagerankcafe-mcp`) wraps every API endpoint as a tool for use
from Claude, Cursor, or any other MCP-compatible client:

```
npx pagerankcafe-mcp
```

Configure it with your API key as the `PAGERANKCAFE_API_KEY` environment
variable.
