# Collimer

> Collimer measures how visible a brand is in AI search — ChatGPT, Perplexity, Google AI Overviews, and other answer engines — and shows the gaps to fix. It runs a free AI-visibility scan on any website and returns a score, a confidence interval, and the single biggest gap, with a branded report link.

The public free-scan API is **depth-gated**: it returns the score, the top gap, and a branded report URL only — never the full report. Share of voice across each AI engine and every recommendation unlock with a free account on the web. The API is public, no-auth, with built-in budget caps and rate limits.

## Free-scan API (for agents and crawlers)

- Start a scan: `POST https://app.collimer.com/api/v1/scan` with `{"url": "example.com", "source": "agent"}`
- Poll the result: `GET https://app.collimer.com/api/v1/scan/{scan_token}` (202 while running, 200 with the teaser when done)
- The teaser returns: `score` (0–100), `confidence_interval`, `top_gap`, `report_url`, `cta_url`.
- Agents should send `source` as `mcp` or `agent` so the scan is attributable.

## Run it inside an agent

- A `beacon_free_scan` Claude Code skill runs a scan via the API and returns the teaser.
- An MCP server (so any MCP-capable agent can run scans natively) is in progress.
