## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

## ATS Tech Stack Scraper

**💰 $5.05 / 1 000 rows** &nbsp;·&nbsp; pay only for results &nbsp;·&nbsp; no credit card to try

_We do the dirty work so your dataset stays clean._ 😈

**B2B tech-stack intel from public job posts — no $39-$399/mo SaaS bill.** Point this Actor at any company's Greenhouse, Lever or Ashby board and get one structured row per active job, including a deduplicated list of canonical tech names (Postgres, Django, AWS, Kubernetes...) detected directly from the job description.

Sales reps qualifying accounts, recruiters sourcing by skill, and competitive-intelligence analysts mapping vendor footprint all need this signal. Commercial tools (TheirStack, Wappalyzer, BuiltWith) charge subscription fees for the same data. This Actor hits the **public ATS APIs directly** — no scraping, no browser, no auth — and emits a flat, Pydantic-validated dataset ready for any CRM enrichment pipeline.

### 🎯 What this scrapes
Three ATS platforms, one schema:

1. **Greenhouse** — `boards-api.greenhouse.io/v1/boards/{token}/jobs?content=true` (public, no auth)
2. **Lever** — `api.lever.co/v0/postings/{token}` (public, no auth)
3. **Ashby** — `api.ashbyhq.com/posting-api/job-board/{token}` (public, no auth; token is **case-sensitive** — `Ramp`, not `ramp`)

For each active job posting the Actor pulls the title, location, department, full HTML/plain-text description, and the public URL — then runs a case-insensitive word-boundary regex against a curated vocabulary of ~110 canonical tech names. The result is a single column you can pivot or filter without per-company string normalization.

| Field | Type | Description |
|---|---|---|
| `ats` | string | `greenhouse`, `lever`, or `ashby` |
| `company_token` | string | Board slug passed to the ATS |
| `job_id` | string | ATS-canonical job id |
| `title` | string | Job posting title |
| `location` | string \| null | Location string (Remote, NYC, Berlin...) |
| `department` | string \| null | Department / team |
| `url` | string | Public job-post URL |
| `description_text` | string | Plain-text description (HTML stripped) |
| `detected_techs` | string[] | Sorted, deduplicated canonical tech names |
| `posted_at` | string \| null | ISO 8601 UTC publication timestamp |
| `scraped_at` | string | ISO 8601 UTC row-creation timestamp |

### 🔥 Features
- **Three ATSs, one schema** — Greenhouse, Lever, Ashby normalized to identical row shape.
- **Curated tech vocabulary** — ~110 canonical names spanning languages (Python, Go, Rust), frameworks (Django, React, FastAPI), databases (Postgres, MongoDB, Redis, Snowflake), cloud (AWS, GCP, Azure, Vercel), infra (Kubernetes, Terraform, Docker), CI/CD, observability, and ML/data tools.
- **Per-company isolation** — one bad token (404 from Lever, typo on Ashby) does not abort the run; the others still produce data.
- **No browser, no auth** — pure HTTP with `curl-cffi` browser-TLS impersonation; low compute footprint and fast runs.
- **Pydantic v2 validation** — every input and every output row is model-validated.
- **Filter knobs** — `maxJobsPerCompany` cap and `minTechsDetected` floor.
- **Exponential backoff** on 429 / 503 with `Retry-After` honoured.

### 💡 Use cases
- **B2B sales qualification** — enrich every Salesforce/HubSpot account with the company's live tech stack: "they hire Django + Postgres + AWS" tells you whether to pitch your Postgres-tuning SaaS.
- **Recruiter sourcing** — pull every "Senior Backend Engineer" role from your target accounts and filter by `detected_techs` to find teams that match your candidate's stack.
- **Competitive intelligence** — track which competitors are hiring for `Kubernetes` or `Snowflake` and infer their roadmap.
- **CRM enrichment** — replace TheirStack / BuiltWith / Wappalyzer subscriptions for the subset of buyers who publish their stack in JDs anyway.
- **Investment research** — map private-company tech footprint over time without paying for a Crunchbase Pro seat.
- **Open-source stack maps** — feed a public site that ranks the most-hired-for technologies in YC-backed startups.

### ⚙️ How to use it
1. Open the Actor input form.
2. Add one or more `{companyToken, atsType}` pairs under **Companies to scrape** (the form prefills with `airtable` on Greenhouse and `Ramp` on Ashby).
3. (Optional) Set **Max jobs per company** — leave empty for no cap.
4. (Optional) Set **Minimum detected techs** — `2` or `3` drops generic/non-engineering postings.
5. Leave **Use Apify Proxy** off unless you observe rate-limiting (public ATS APIs do not require it).
6. Click **Start**. Rows stream into the default dataset.

#### Quick examples

**Two engineering-heavy companies, default settings:**

```json
{
  "companies": [
    { "companyToken": "airtable", "atsType": "greenhouse" },
    { "companyToken": "Ramp", "atsType": "ashby" }
  ]
}
````

**Single Lever company, drop sales/marketing roles:**

```json
{
  "companies": [
    { "companyToken": "palantir", "atsType": "lever" }
  ],
  "minTechsDetected": 3
}
```

**Three companies across all three ATSs, capped at 50 jobs each:**

```json
{
  "companies": [
    { "companyToken": "airtable", "atsType": "greenhouse" },
    { "companyToken": "palantir", "atsType": "lever" },
    { "companyToken": "Ramp", "atsType": "ashby" }
  ],
  "maxJobsPerCompany": 50,
  "minTechsDetected": 2
}
```

### Pricing (Pay-Per-Event)

| Event | Price | When |
|---|---|---|
| `actor-start` | $0.05 | Once per run |
| `result-row` | $0.005 | Per job row emitted |

A typical 50-job run costs `$0.05 + 50 × $0.005 = $0.30`. Compare to TheirStack at $39-$399/month for the same signal.

### How to find a company's ATS token

- **Greenhouse**: the path segment in `boards.greenhouse.io/{token}` or `{token}.applytojob.com`. Examples: `airtable`, `figma`, `stripe`.
- **Lever**: the path segment in `jobs.lever.co/{token}`. Examples: `palantir`, `netflix`, `eventbrite`.
- **Ashby**: the path segment in `jobs.ashbyhq.com/{Token}`. **Case-sensitive** — `Ramp`, `PostHog`, `Linear` work; the lowercase variants return zero jobs.

### Output and limits

- Rows are pushed to the default Apify dataset as they are produced — long runs surface rows immediately.
- Apify FREE-tier default storage retains datasets for 7 days; use `Actor.open_dataset(name="...")` if you need to outlive that.
- The Actor exits successfully when at least one company yields one or more jobs. If every company returns zero (e.g. all tokens were misspelled), the run fails loud with a non-zero exit code.

### Notes and caveats

- Tech detection is regex-based, not LLM-based — it is deterministic, free, and high-precision but will miss tools whose names are not in the curated vocabulary. Open a feedback request to add more.
- Greenhouse `content` is double-HTML-encoded (e.g. `&lt;div&gt;` for `<div>`); the parser unescapes twice before stripping tags.
- Lever's `descriptionPlain` often omits the "Requirements" bullet list; the parser concatenates every `lists[].content` chunk so skills hidden there are still detected.
- Ashby exposes both `descriptionHtml` and `descriptionPlain` — the parser prefers `descriptionPlain` when present.

# Actor input Schema

## `companies` (type: `array`):

List of <code>{companyToken, atsType}</code> pairs. <code>atsType</code> is one of <code>greenhouse</code>, <code>lever</code>, <code>ashby</code>. <code>companyToken</code> is the board slug in the ATS URL (e.g. <code>airtable</code> for Greenhouse, <code>palantir</code> for Lever, <code>Ramp</code> for Ashby — Ashby is case-sensitive).

## `maxJobsPerCompany` (type: `integer`):

Hard cap on rows emitted per company. Leave empty for no cap.
