Greenhouse, Lever, Ashby, Workable, Teamtailor Jobs API

One API for six applicant tracking systems: Greenhouse, Lever, Ashby, Workable, Teamtailor and SmartRecruiters.

Give it a company website. It finds the job board itself, returns every open role, and on every run after that returns only what changed — roles opened, roles closed, titles moved, salaries changed — plus derived hiring signals.

{ "domains": ["stripe.com", "spotify.com", "pleo.io"] }

No board tokens. No ATS knowledge required. No browser.

Two ways to run it

The logic is the same code in both. Pick whichever fits.

What you get

Every record carries provenance: source URL, HTTP status, fetch time, job count, truncation flag and a confidence value — so an agent can verify before it acts, instead of trusting a claim.

MCP server

npx ats-jobs-mcp

Four tools, usable by any MCP client — Claude Desktop, Cursor, VS Code, your own agent:

Claude Desktop config:

{
  "mcpServers": {
    "ats-jobs": { "command": "npx", "args": ["-y", "ats-jobs-mcp"] }
  }
}

State lives in ~/.ats-jobs-mcp/state.json. Override with ATS_MCP_STATE.

Why it stays cheap to run continuously

Every source is polled with If-None-Match. When nothing changed, the ATS answers 304 with no body.

Measured on the hosted Actor at 512 MB:

That is why watching hundreds of companies every few hours costs cents rather than dollars — and why this project will never open a headless browser to read a job board.

What it deliberately does not do

• No personal data. Recruiter names, emails and phone numbers are stripped at parse time and never stored.

• No headless browser, no proxies. Only public ATS endpoints that answer with JSON.

• No false layoffs. If a source response may be truncated by paging, job_closed events are suppressed — a paging artefact must never look like a company shutting down hiring.

Supported sources

greenhouse · lever · ashby · workable · teamtailor · smartrecruiters

Detection order: a link on the company careers page → the board token guessed from the domain → Workable short links resolved through their redirect.

Companies that cannot be resolved return a source_unresolved record explaining why, instead of failing silently.

Recruitee and Personio are not listed because they are not verified working. Personio currently answers 429 to non-browser clients; Recruitee endpoints did not resolve in testing. This project does not claim coverage it cannot deliver.

Repo layout

src/          Apify Actor: adapters, diff engine, derived signals
mcp/          MCP server — the same engine, self-hosted
tools/        discovery utilities (domain → ATS)
.actor/       Apify manifests and schemas
