**No code:** open any Actor above, enter the input, and click **Start**.  
**API:** use the copy-paste examples below or open the dedicated guide.  
**AI agent / MCP:** connect the single remote endpoint below and choose the tool you need.

> Pricing can change. Use each Actor's live **Pricing** tab in Apify as the source of truth.

## Install as an Agent Skill

Signal Lab also ships a portable Agent Skill that teaches compatible agents when and how to route public-data work through the focused Apify Actors and Official MCP tools without embedding owner credentials.

**Verified external Agent Skill listing:** https://askill.sh/skills/703900  
**OpenAgentSkill:** submitted for review; not counted here as a verified public listing until independent read-back confirms it.

Install from the verified askill registry entry:

```bash
npx askill-cli add gh:VZezelin/first@signal-lab-apify-tools -y
```

Or list/install directly from this public GitHub repository:

```bash
npx skills add VZezelin/first --list
npx skills add VZezelin/first --skill signal-lab-apify-tools -a codex -y --copy
```

The public install path has been verified from a clean workspace. The skill itself is at [`skills/signal-lab-apify-tools/SKILL.md`](https://github.com/VZezelin/first/blob/HEAD/skills/signal-lab-apify-tools/SKILL.md). Installing the skill does not supply Apify credentials; paid Actor or MCP execution still uses the installer's own Apify authentication.

## Official MCP Registry

Signal Lab is published in the **Official Model Context Protocol Registry** as:

`io.github.VZezelin/signal-lab-apify-tools`

Registry search: https://registry.modelcontextprotocol.io/?q=io.github.VZezelin%2Fsignal-lab-apify-tools  
Verified MCPRepository mirror: https://mcprepository.com/VZezelin/first

The registered remote uses Apify's hosted Streamable HTTP MCP endpoint and exposes a focused set of Signal Lab tools:

```json
{
  "mcpServers": {
    "signal-lab": {
      "url": "https://mcp.apify.com?tools=signal_lab/amazon-price-tracker,signal_lab/google-autocomplete-keywords,signal_lab/website-to-markdown-crawler,signal_lab/youtube-transcript-scraper,signal_lab/reddit-search-comments,signal_lab/job-vacancy-scraper,signal_lab/restaurant-menu-extractor"
    }
  }
}
```

Apify handles the MCP connection and authentication flow. Actor pricing remains defined by each Actor's live Apify Pricing tab.

## 1. Amazon Price Tracker API — track an ASIN and build price-drop alerts

**Run in Store:** https://apify.com/signal_lab/amazon-price-tracker

Useful for:
- Amazon price tracking by ASIN/product URL
- price history pipelines
- price-change and price-drop alerts
- scheduled competitor monitoring

Run through the Apify API:

```bash
curl -X POST \
  "https://api.apify.com/v2/acts/signal_lab~amazon-price-tracker/runs" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "productUrls": ["https://www.amazon.com/dp/0132350882"],
    "emitOnlyChanges": false,
    "proxyConfiguration": {"useApifyProxy": false},
    "maxItems": 10
  }'
```

For alerts, run it on an Apify schedule and connect a webhook/Make/n8n flow to the resulting dataset.

## 2. Google Autocomplete API — buyer-intent keyword suggestions

**Run in Store:** https://apify.com/signal_lab/google-autocomplete-keywords

Useful for:
- Google Autocomplete keyword research
- commercial modifiers such as `cost`, `pricing`, `free`, `alternative`, and `API`
- country/language-specific long-tail research
- programmatic SEO and demand discovery

```bash
curl -X POST \
  "https://api.apify.com/v2/acts/signal_lab~google-autocomplete-keywords/runs" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "queries": ["google autocomplete api"],
    "language": "en",
    "country": "us",
    "expandAlphabet": false,
    "includeQuestions": false,
    "maxResults": 20
  }'
```

## 3. Website to Markdown API — clean pages for RAG and LLM ingestion

**Run in Store:** https://apify.com/signal_lab/website-to-markdown-crawler

Useful for:
- website-to-Markdown conversion
- clean RAG/LLM source documents
- headings, links, metadata, and structured page extraction
- one-page API calls or bounded website crawls

```bash
curl -X POST \
  "https://api.apify.com/v2/acts/signal_lab~website-to-markdown-crawler/runs" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "startUrls": [{"url": "https://example.com"}],
    "maxPages": 1,
    "maxDepth": 0,
    "sameDomainOnly": true,
    "useSitemaps": false,
    "respectRobotsTxt": true
  }'
```

## 4. YouTube Transcript API — captions, timestamps, and metadata

**Run in Store:** https://apify.com/signal_lab/youtube-transcript-scraper  
**API guide:** [youtube-transcript-api.md](https://github.com/VZezelin/first/blob/HEAD/youtube-transcript-api.md)

Useful for:
- public YouTube transcripts
- timestamped caption segments
- RAG and semantic search
- research, summarization, and indexing workflows

The dedicated guide includes the current input fields, a copy-paste API call, and the focused MCP configuration.

## 5. Job Posting Scraper API — structured vacancy data from a public job URL

**Run in Store:** https://apify.com/signal_lab/job-vacancy-scraper  
**API guide:** [job-posting-scraper-api.md](https://github.com/VZezelin/first/blob/HEAD/job-posting-scraper-api.md)

Use it when you already have public vacancy URLs and need structured fields for ATS ingestion, recruiting automation, hiring-market monitoring, or downstream CSV/JSON workflows. The Actor can return job title, company, location, salary/currency when present, employment type, published/valid-through dates, source URL, and structured `JobPosting` metadata exposed by the page. Missing source fields are not invented.

Minimal API call:

```bash
curl -X POST \
  "https://api.apify.com/v2/acts/signal_lab~job-vacancy-scraper/runs" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["https://example.com/public-job-posting"],
    "maxJobs": 5,
    "maxItems": 5
  }'
```

This is a page-to-structured-data workflow; it does not claim to search every job board or bypass login walls.

## MCP / AI-agent usage

The Official MCP Registry entry above is the canonical discovery record for this Signal Lab tool bundle. You can also configure the same Apify-hosted endpoint directly in MCP-compatible clients.

After authentication, an agent can request tasks such as:
- “Track this Amazon ASIN and return the current price.”
- “Find Google Autocomplete suggestions for this buyer-intent keyword.”
- “Convert this page to clean Markdown for a RAG pipeline.”
- “Get this public YouTube transcript with timestamps.”
- “Search Reddit for recent product feedback and return source URLs.”
- “Extract structured fields from this public job posting.”
- “Extract menu items and prices from this restaurant page.”
