Job Board New-Posting Monitor

Be the first to know when a job is posted — not the fiftieth to scrape the same board.

This monitor watches your searches on USAJobs (US federal jobs) and arbeitnow (remote-friendly jobs) and reports only genuinely new postings. Run it on a schedule; when nothing new appeared, it pushes nothing and charges nothing.

Why it's different

• Cross-run dedup built in. Other actors dump the same postings every morning (and bill you for every row). This one remembers what it already reported and surfaces only what changed.
• First-party APIs only. USAJobs' official API and arbeitnow's free public API — no fragile HTML scraping, no LinkedIn/Indeed terms-of-service risk, no proxy bills.
• Pay per new posting, not per row. You are billed per genuinely new job delivered, never for re-delivering an unchanged list. A scheduled run that finds nothing new costs only the $0.001 start.
• Multi-query from day one. Add up to 20 searches in one run; every row is tagged with the searchQuery that found it.
• Freshness filter. postedWithinDays (USAJobs) ignores stale postings, so your first run starts clean instead of flooding you with months-old jobs.
• Auditable runs. Every run writes a machine-readable receipt (<stateKey>-last-receipt in the state store) with per-search fetch counts, new/removed counters, and any errors.
• Separate memories. Give each scheduled monitor its own stateKey and their baselines never mix.

Coverage note: the only other new-job monitor in the Store covers remote boards only (and arbeitnow solely as an opt-in remote-rows feed). Nobody monitors USAJobs, and nobody monitors the full arbeitnow board — this actor does both.

Inputs

Field	What it does
searches	Your searches. Each has a source (usajobs or arbeitnow), a keyword, and source-specific options (USAJobs: locationName, resultsPerPage, postedWithinDays; arbeitnow: remoteOnly, location, maxJobs).
usajobsApiKey	Free key from data.usajobs.gov — sign in, request API access. Required only for USAJobs searches; arbeitnow needs no key. Without it, USAJobs searches are skipped gracefully (arbeitnow still runs).
stateKey	Namespace for this monitor's memory. Use a different key per schedule. The prefilled default key rotates daily so the free trial always shows recent postings.
reportInitialAsNew	First run reports everything as new. Turn off to build the baseline silently.
detectRemoved	Also report postings that disappeared (filled/expired). Needs 2 consecutive misses to avoid false alarms.

Example input:

{
  "searches": [
    {"source": "usajobs", "keyword": "data analyst", "locationName": "New York, New York", "postedWithinDays": 7},
    {"source": "arbeitnow", "keyword": "software engineer", "remoteOnly": true}
  ],
  "usajobsApiKey": "YOUR_FREE_KEY",
  "stateKey": "morning-alerts"
}

Output

One dataset row per new posting:

Field	Example
changeType	new (or removed)
source	usajobs / arbeitnow
title	Data Analyst
company	Department of Veterans Affairs
location	Washington, DC
url	direct link to the posting
postedDate	2026-09-22
remote	yes/no (arbeitnow)

Pricing

Pay-per-event:

• Actor start: $0.001
• New posting delivered: $0.0015

A scheduled run that finds nothing new costs only the $0.001 start. Compare: per-row actors bill you for every posting they re-deliver, every run.

Notes

• arbeitnow is a free public API — please don't abuse it; their terms ask you to link back to arbeitnow.com.
• USAJobs requires the free Authorization-Key; the monitor sends the required User-Agent and Host headers for you.
• removed rows are informational and are never billed.
