# Foglift — SEO + GEO Website Intelligence Platform

> The first website analysis tool that combines traditional SEO and Generative Engine Optimization (GEO). Free instant scans, REST API, CLI, and MCP server for AI agents.

## What is Foglift?

Foglift scans any URL and provides structured analysis across 6 categories:
1. **SEO** (25%) — Meta tags, headings, Open Graph, canonical URLs, image alt text, robots directives, sitemap
2. **GEO** (25%) — AI crawler access (GPTBot, ClaudeBot, PerplexityBot), structured data, FAQ sections, entity markup, citation formatting
3. **Performance** (20%) — Core Web Vitals (LCP, CLS, INP), load time, Speed Index via Google PageSpeed
4. **Security** (15%) — HTTPS, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy
5. **Accessibility** (15%) — WCAG 2.1, color contrast, alt text, keyboard navigation, ARIA labels
6. **AEO** — AI Engine Optimization citability score across 8 dimensions (Structured Data Richness, Heading Clarity, FAQ Quality, Entity Identity, Content Depth, Citation Formatting, Topical Authority, AI Crawler Access)

## AI Brand Visibility Check

Foglift queries five AI search engines daily and reports whether your brand is mentioned: ChatGPT (with web search), Perplexity, Google AI Overview, Claude, and Gemini. Each engine is a separate query channel, so a single prompt returns five independent visibility results. Try it at https://foglift.io/try-ai

## For AI Agents

### MCP Server (recommended for agent integrations)

Install: `npm install -g foglift-mcp`
Config: `{ "mcpServers": { "foglift": { "command": "npx", "args": ["foglift-mcp"] } } }`
Transports: stdio (default) and streamable HTTP (`--transport http`).
Current version: 1.2.0.

The server exposes 14 tools:

1. `scan_website` — Scan a URL for SEO, GEO, and AI search readiness. Returns overall score, category scores, and a list of specific issues with fix suggestions.
2. `batch_scan` — Scan multiple URLs in one request (max 10). Requires API key.
3. `run_ai_visibility` — Query AI models (ChatGPT, Claude, Perplexity, Gemini, Google AI Overview) with prompts about your domain. Returns per-model results with citation status and sentiment.
4. `get_ai_results` — Historical AI visibility results for your domain, filterable by days, model, and prompt.
5. `get_prompts` — List your saved AI visibility monitoring prompts.
6. `add_prompt` — Add a new prompt to the monitored set. Optional category.
7. `delete_prompt` — Remove a saved prompt by ID.
8. `get_models` — List your enabled AI models and monitoring frequency.
9. `set_models` — Update enabled models and monitoring frequency (daily, weekly, monthly).
10. `get_sentiment` — Brand sentiment analysis across AI models (positive / neutral / negative) with trends.
11. `get_usage` — API usage statistics: scan count, AI visibility checks, quota remaining.
12. `get_scan_history` — Historical scans for a specific URL showing score changes over time.
13. `get_geo_monitor` — GEO monitoring history showing how AI optimization scores change over time.
14. `whoami` — Return the authenticated account identity: user_id, plan, default workspace (name + domain), current token balance, and monthly allocation.

### REST API

### CLI

Install: `npm install -g foglift-scan`
Example: `foglift-scan https://example.com --json`
Full command reference: https://foglift.io/docs

### AI Crawler Tracker (@foglift/tracker)

Install: `npm install @foglift/tracker`
Tracks which AI engines (ChatGPT, Claude, Perplexity, Gemini, Google AI Overview) crawl your site in real time. Middleware adapters for Next.js, Express, and generic Node.js.
Dashboard: https://foglift.io/dashboard/crawlers

### Webhooks

`POST /api/v1/webhooks` with body `{ "url": "https://your-endpoint.com/hook", "events": ["scan.completed", "score.changed"] }`

## Authentication

All authenticated endpoints accept either header. Pick one; you do not need both:

- `Authorization: Bearer sk_fog_...` — standard OAuth-style bearer token
- `X-API-Key: sk_fog_...` — equivalent, recommended for simple clients

API keys start with the prefix `sk_fog_` and are minimum 20 characters. Generate one at https://foglift.io/dashboard/settings. The `/api/v1/scan` endpoint works anonymously on the free-tier quota — all other endpoints require a key.

## Error codes

- `401 Unauthorized` — Missing, malformed, or deactivated API key.
  - "API key required. Pass via X-API-Key header." — header absent.
  - "Invalid API key format. Keys start with sk_fog_" — wrong prefix.
  - "API key not found" — hash does not match any stored key.
  - "API key is deactivated — reactivate in Settings → API Keys" — key exists but is disabled.
- `404 Not Found` — Endpoint path is wrong or the resource (prompt ID, scan ID) does not exist.
- `429 Too Many Requests` — Daily rate limit exceeded for your plan (see table below). Response body includes `{ used, limit, remaining }`. Retry after 24h window rolls over, or upgrade your plan.
- `500 Internal Server Error` — Transient server issue. Safe to retry once with exponential backoff. If it persists, check https://foglift.io/status.

## Rate limits

Scans per 24-hour rolling window, by plan:

| Plan       | Scans / 24h |
|------------|-------------|
| free       | 10          |
| starter    | 100         |
| launch     | 100         |
| pro        | 500         |
| growth     | 500         |
| enterprise | 2,000       |
| agency     | 5,000       |

Rate limits are enforced per API key, tracked over a rolling 24-hour window. The `GET /api/v1/usage` endpoint returns your current `used`, `limit`, and `remaining` counts.
