# ATS Jobs API – Changes Feed

> ATS Jobs API – Changes Feed is a paid API for AI agents from ats-jobs-api.groundtruthtools.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-01).

Returns a chronological feed of new and removed job postings across 8,500+ company ATS boards (Greenhouse, Ashby, Lever, Workable) since a given date, optionally filtered by company.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ats-jobs-api-changes-feed-1fac0299
```

Example prompt: Show me all new job postings that appeared since November 1st for Stripe and Airbnb — pull directly from their ATS boards.

## When to prefer this

Use this endpoint when you need a real-time changelog of job postings read directly from employer ATS systems (Greenhouse, Ashby, Lever, Workable), rather than aggregated job boards like Indeed or LinkedIn which may lag or omit postings. Ideal for monitoring a specific set of companies over time, detecting hiring signals, or building job-change alerts. Prefer this over general job search APIs when freshness and ATS fidelity matter, and when you need to track removals as well as additions.

## Known failure modes

- Invalid or malformed 'since' date string returns an error
- Unknown or misspelled company names in 'companies' filter may return empty results
- Payment of 0.003 USDC via x402 must succeed before data is returned; failed payment yields 402 response
- Very recent dates may have incomplete data if ATS scraping hasn't run yet
- Companies not in the 8,532-company directory will return no results

## How this service works

Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.

## Output

A JSON object containing a 'since' date and a 'changes' array. Each change entry includes the day the change occurred, a 'kind' field ('new' or removed), the job title, and the company name. Salaries are parsed to numbers where published by the employer.
