Track job change

Check whether one contact, or a list of contacts, still works at the company your records hold. Returns one flat, Clay-ready JSON row per person: current employer, title, start month, role history, status (left, landed, promoted, or still there), how the person was matched, the source of the answer, and that source's date, with a namesake check. Runs on data you send (known_history) and on your own Serper or SerpApi, Prospeo, and BounceBan keys passed as inputs; this tool never fetches LinkedIn and holds no key of its own. Provide person_name with company_domain or company_name, or a people list. A run that does not succeed is returned as an error with its run ID. Reads public data and writes nothing; requires an APIFY_TOKEN and consumes Apify credits per call.

Input parameters:

- `bouncebanApiKey` (string): Optional. Verifies the old work address only while the person still reads as at the company. Only an undeliverable answer is used. Your own key, sent as a run input; never stored by the actor.
- `cacheTtlDays` (string): Reuse a reading made in the last N days, uncharged, from a store in your own Apify account. 0 turns it off. Rows with your own history are never cached. Default 7.
- `checkCompanySite` (string): Free. Looks for the person on up to 4 team and about pages of the last known company domain.
- `checkNews` (string): Free. Cites up to 3 headlines from the last year that name the person with a move word. Evidence only; a headline never sets the employer.
- `company_domain` (string): Website domain of the company your records place this person at, for example microsoft.com. Left, landed, and promoted are worked out against this company.
- `company_linkedin_url` (string): Optional. The strongest company match when a role history carries LinkedIn company URLs.
- `company_name` (string): Name of that company. Used with or instead of the domain to match roles in the person's history.
- `email` (string): Optional. The person's work address at the last known company. With a BounceBan key, an undeliverable answer marks the person as left.
- `includeRoleHistory` (string): No keeps role_count and drops the role_history array.
- `input_id` (string): Optional. Returned unchanged on the row so you can join it back to your CRM or table.
- `known_history` (string): Optional. A role history you already have, as JSON: {"source": "heyreach", "source_date": "2026-10-07", "experiences": [...]} or {"source": "crm", "roles": [{"company_name", "title", "start_month", "…
- `last_known_title` (string): The title your records hold. Echoed on the row as input_title.
- `location` (string): Optional. Echoed for your records.
- `maxPeople` (string): Stop after this many people. Default 1000.
- `maxSourceAgeDays` (string): A history you send that is older than this is treated as lagging, so the run also reads Prospeo and the search result. Default 30.
- `max_charge_usd` (string): Optional. The run stops before any row that would take its event charges past this amount.
- `people` (array): Many people at once. Each item takes the same keys as the single person fields: person_name, company_domain, company_name, last_known_title, profile_url, email, company_linkedin_url, location, input_…
- `person_name` (string): Full name of the person to check.
- `profile_url` (string): Optional. The person's LinkedIn profile URL, used as the identity. This actor never opens it. Without it, the run looks the profile up with your search key and charges profile_resolved when it finds…
- `prospeoApiKey` (string): Optional. Prospeo enrich-person: the person's role history with start and end months. Skipped when you send a fresh history of your own. Your own key, sent as a run input; never stored by the actor.
- `serpApiKey` (string): Optional. Used for web search only when no Serper key is set. Your own key, sent as a run input; never stored by the actor.
- `serperApiKey` (string): Optional. Web search (serper.dev): finds profile URLs and reads the search result line for the current role. About 1 to 3 searches per person. Your own key, sent as a run input; never stored by the a…
- `verifyOldEmail` (string): With a BounceBan key: one check per person who still reads as at the company. Uses the address you send, or one Prospeo returns on the company domain.
