## Zero-auth sandbox

The sandbox surface needs no signup, credential, or key:

```bash
curl https://api.appskyline.com/api/sandbox/keywords
```

It returns demonstration keyword-rank rows in the same shape as authenticated keyword reads, carries the standard `RateLimit` headers, and accepts a demonstration [async rank check](https://www.appskyline.com/api.md) at `POST /api/sandbox/rankchecks`. Production keys come from self-serve signup at https://app.appskyline.com/signup — the free tier issues scoped API keys instantly, with no sales or approval step.

## Agent access

### Choose the least-privilege interface

Connect the OAuth-protected Streamable HTTP MCP server at https://mcp.appskyline.com/mcp, use the REST API with a scoped credential, or use the public AppSkyline CLI. The MCP server is published for Claude and ChatGPT and exposes read tools plus approval-gated keyword changes.

### CLI quick start

- Install globally: `npm install -g appskyline`
- Run without installing: `npx appskyline --help`
