How to pull open jobs from Greenhouse, Lever and Ashby without scraping HTML

Detroit Web Agent — Tue, 20 Oct 2026 19:17:10 +0000

Most applicant-tracking systems publish their job boards as public JSON. No login, no HTML parsing, no headless browser. Here is how to use them, and when a ready-made tool is worth it.

The three public endpoints

ATS	Endpoint	Slug example
Greenhouse	`https://boards-api.greenhouse.io/v1/boards/{slug}/jobs?content=true`	`gitlab`
Lever	`https://api.lever.co/v0/postings/{slug}?mode=json`	`palantir`
Ashby	`https://api.ashbyhq.com/posting-api/job-board/{slug}`	`ashby`

The slug is the company's board name, visible in its careers-page URL (boards.greenhouse.io/gitlab, jobs.lever.co/palantir, jobs.ashbyhq.com/ashby).

Normalize them in ~20 lines of Python

import requests

def greenhouse(slug):
    r = requests.get(f"https://boards-api.greenhouse.io/v1/boards/{slug}/jobs", timeout=30).json()
    return [{"title": j["title"], "location": (j.get("location") or {}).get("name"),
             "url": j["absolute_url"], "posted": j.get("updated_at")} for j in r["jobs"]]

def lever(slug):
    r = requests.get(f"https://api.lever.co/v0/postings/{slug}", params={"mode": "json"}, timeout=30).json()
    return [{"title": j["text"], "location": j["categories"].get("location"),
             "url": j["hostedUrl"], "posted": j["createdAt"]} for j in r]

def ashby(slug):
    r = requests.get(f"https://api.ashbyhq.com/posting-api/job-board/{slug}", timeout=30).json()
    return [{"title": j["title"], "location": j.get("location"),
             "url": j["jobUrl"], "posted": j.get("publishedAt")} for j in r["jobs"]]

for fn, slug in [(greenhouse, "gitlab"), (lever, "palantir"), (ashby, "ashby")]:
    jobs = fn(slug)
    print(slug, len(jobs), jobs[0]["title"])

Add a remote flag by checking the location string for "remote", and store posted as ISO dates (Lever gives epoch milliseconds).

Finding the slug from a domain

Fetch the company's /careers page and look for links to boards.greenhouse.io/, jobs.lever.co/ or jobs.ashbyhq.com/. Many sites embed the board in an iframe or script tag; the slug is in that URL. When there is no match, try the domain name itself as the slug.

When a ready-made tool beats your script

If you track hundreds of companies, you also need Workable, Recruitee and SmartRecruiters, retries, and de-duplication. Disclosure: I built an Apify actor for exactly that: ats-open-roles. Give it company slugs or domains, get normalized open roles back. It is pay-per-result at $0.002 per job, so 1,000 roles cost about $2. If you only need a handful of companies, the script above is the better deal.

Block fake and typo emails at signup in about 15 lines

If you let any email into your database, you'll eventually pay for it. Typos, throwaway inboxes, dead domains. They bounce, they tank your sender reputation, and your real emails start landing in spam. Here's how I block them at signup.

The idea

Check the address before you save it. Keep the good ones, recover typos, drop the junk.

The code (Node)

const res = await fetch("https://YOUR-RAPIDAPI-HOST/", {

  method: "POST",

  headers: {

    "Content-Type": "application/json",

    "X-RapidAPI-Key": "YOUR_KEY",

    "X-RapidAPI-Host": "YOUR-RAPIDAPI-HOST"

  },

  body: JSON.stringify({ email: req.body.email })

});

const r = await res.json();

if (r.status === "invalid" && r.did_you_mean) {

  return reject(Did you mean ${r.did_you_mean}?);   // recover the typo

}

if (r.status === "invalid" || r.checks.disposable) {

  return reject("Please use a valid, non-disposable email.");

}

// r.status === "valid" -> save it

What comes back

A verdict (valid / invalid / risky), a 0-100 score, and a per-check breakdown: syntax, MX (dead domain), disposable, role-based, free-webmail, plus a did_you_mean typo suggestion.

One honest caveat

It doesn't do SMTP mailbox probing. That gets you blocked and hurts your sending IP, so it's left out and the response says smtp_check: "skipped". It still catches typos, fakes, dead domains and role inboxes, which is the bulk of bad signups.
