How this service works
Cheap watchdog for closed/materially changed job state. Base mainnet USDC
Output
Returns a signal indicating whether the job posting has materially changed or been closed compared to the supplied previous hash, along with the current content hash for future comparisons.
Example use cases
Closed job alert for pipeline monitoring
“I'm tracking dozens of open roles in my candidate pipeline — can you check if the Lever job at https://jobs.lever.co/startup/abc-456 with job ID abc-456 has closed or changed since my hash 'f3a9c1d8b2e7'?”
Stale listing cleanup in job aggregator
“We scraped an Ashby job listing last week with hash 'e2b7a943c1f0' — check if https://jobs.ashbyhq.com/company/job-789, job ID job-789, has changed so we know whether to refresh or remove it from our index.”
Application timing watchdog
“I applied to a job and want to know if the posting at https://boards.greenhouse.io/bigcorp/jobs/99001 on Greenhouse (job ID 99001) has been closed or materially edited since I saved hash 'b1c2d3e4f5a6' a few days ago.”
Technical details
Endpoint
POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/job/changed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, lightweight signal about whether a specific job posting has changed or closed, without re-fetching and re-parsing the full job description. Ideal for high-volume monitoring pipelines where full scrapes are expensive. Supports Greenhouse, Lever, and Ashby specifically; prefer over generic web-change detectors when working within these ATS ecosystems.
Side effects
- Job URL unreachable or returns non-200 — returns error or change signal as closed
- Invalid or unsupported ATS provider enum — validation error
- Previous hash not supplied — treated as first-time check, always returns changed
- Job ID not found on specified board — returns not-found or closed signal
- Rate limiting or network timeout from ATS provider — may return transient error
