Tool

`monitor_job_postings`

Give it a list of role keywords and it returns the companies currently advertising those roles, one flat row per posting, each enriched with firmographics and the company LinkedIn URL.

Input	Type	Required	Notes
`keywords`	array	yes	Editorial / content role titles to search for across job boards.
`sources`	array	no	Which job boards to search: `google_jobs` (needs a SerpAPI key) plus four that need no credentials at all, `jobicy`, `remotive`, `arbeitnow` and `themuse`. Select several; a posting carried by two boards is deduplicated and counted once. Default `["google_jobs"]`.
`country`	string	no	Geographic filter, e.g. United States, United Kingdom, Canada.
`lookback_days`	integer	no	Only return postings newer than this many days.
`company_size_min`	integer	no	Optional. Drop companies with fewer employees than this (only applied when company size is known).
`company_size_max`	integer	no	Optional. Drop companies larger than this (only applied when company size is known).
`exclude_staffing_agencies`	boolean	no	Filter out staffing and recruitment agency postings using name and job-description heuristics.
`exclude_freelance_marketplaces`	boolean	no	Filter out postings where the company is a freelance marketplace (Upwork, Fiverr, etc.), which are noise for direct outreach.
`freelance_marketplaces`	array	no	Company names treated as freelance marketplaces and excluded when the toggle above is on. Defaults shown; override or extend as needed.
`remote_only`	boolean	no	Only return remote / work-from-home postings.
`previous_run_date`	string	no	Optional ISO date (e.g. 2026-06-01) of your last run. Only postings newer than this are emitted, on top of the built-in cross-run delta cache.
`max_results`	integer	no	Upper bound on raw postings pulled from the discovery source before filtering. Higher values cost more.
`max_companies`	integer	no	Cap on unique companies enriched per run (firmographics + LinkedIn). Bounds sub-actor cost.
`serpapi_key`	string	no	SerpAPI key used for Google Jobs discovery (get a free key at serpapi.com, 250 searches/month, no card). Required to produce results unless a SERPAPI_KEY environment variable is set on the actor.

Billing

You are charged per result row returned, plus a small actor start fee. Filtered postings are free.

Pricing is on the actor's Apify page. Running this server consumes Apify credits.

What this server does and does not do

It is a thin client for the Apify actor. It passes your input through and returns the actor's output unchanged. Every behavior described above lives in the actor, not here.

Errors are surfaced, never swallowed. An invalid input, an invalid token, an exhausted balance, a timeout, or a run that returns anything other than a dataset all come back as an explicit tool error rather than as an empty result.
