## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Multi-ATS Career Jobs & B2B Tech-Stack Hiring Signal API (MCP-Ready)

Fetch live, verified job postings and **B2B Buying / Tech-Stack Adoption Signals** directly from company ATS career endpoints across **Greenhouse**, **Ashby**, **Lever (US & EU)**, **SmartRecruiters**, and **Recruitee** into a single unified schema — **100% browserless, zero cookies, zero proxy overhead**.

Designed for **Clay.com**, **n8n**, **Make**, B2B Outbound Agencies, Recruiting Automation, and **MCP AI Agents**.

***

### Why Use This Actor?

- **Automatic ATS Detection**: Pass either a career URL (`https://jobs.ashbyhq.com/linear`, `https://boards.greenhouse.io/cloudflare`) **or just a plain company slug** (`linear`, `wise`, `palantir`, `cloudflare`) — the engine concurrently probes all supported ATS APIs and resolves the company's live job board automatically.
- **65+ B2B Tech-Stack Signals Extracted Automatically**: Every job description is scanned for cloud, data, AI, security, and GTM tools (`Snowflake`, `Databricks`, `Kubernetes`, `AWS`, `Terraform`, `OpenAI / LLM`, `Salesforce`, `HubSpot`, `Clay`, `n8n`, `Stripe`, `SOC2`, etc.) so B2B sales teams can trigger hyper-targeted outbound the moment a prospect starts hiring for a specific technology.
- **Normalized Compensation, Seniority & Work Model**: Extracts structured salary ranges (`salaryMin`, `salaryMax`, `salaryCurrency`, `salaryFormatted`), seniority tier (`SENIOR`, `STAFF_OR_PRINCIPAL`, `LEAD_OR_MANAGER`, `C_LEVEL_OR_VP`), and workplace classification (`REMOTE`, `HYBRID`, `ONSITE`).
- **Dual Output Modes**:
  1. `mode: "jobs"` — One enriched record per open role.
  2. `mode: "company_signals"` — One aggregated B2B Hiring-Velocity & Tech-Stack Buying Signal row per company (`hiringVelocityTier`, `b2bHiringIntentScore`, `departmentsBreakdown`, `detectedTechStack`, `remoteJobsCount`) built directly for **Clay.com** company enrichment tables.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config.
