--- title: "Create a job changes watcher agent" method: POST path: "/business/agents/job-changes-watcher" tags: ["Agents"] --- # Create a job changes watcher agent `POST /business/agents/job-changes-watcher` ## Request - Base URL: `https://api.tryfuse.ai/api/v1` - URL: `https://api.tryfuse.ai/api/v1/business/agents/job-changes-watcher` - Auth: HTTP basic Creates a Job-changes watcher (from a list) agent (`job-changes-watcher`). Watches the PEOPLE of an existing list for title/company changes against the provider's monthly dataset releases (exactly one of `listId`/`listIds`). With `start: false` (the default) a DRAFT is saved — status `initializing`, nothing billed: read it back with GET /business/agents/{agentId}, adjust it with PATCH /business/agents/{agentId}, then start it with POST /business/agents/{agentId}/activate. With `start: true` the agent is created AND started in one call: its dedicated results list is created, credits are checked and spent, and the provider subscriptions are set up. Either way the answer is 201 `{ agent: { id, type, name, status, started } }` — the same shape for every agent kind, draft or started. Poll GET /business/agents for `status` and `contactsFound`, and read the delivered rows with the Lists endpoints via the agent's `listId`. Free-plan accounts hold at most 10 agents, drafts included (403 AGENT_LIMIT_REACHED). Every field below is validated by the agents service: a rejected field answers 422 VALIDATION_FAILED, naming it in `param` and describing every failure in `message`. `listName` must not collide with an existing list or agent name (409 LIST_NAME_TAKEN), and starting without enough credits answers 402 INSUFFICIENT_CREDITS without creating anything. Errors: - `422` `VALIDATION_FAILED` — The request was rejected by validation. Either this endpoint's own request validation (a malformed body), or the agent config itself: a field missing, out of range or not one of the accepted values, or a business rule broken (an `expirationDate` that is not in the future, more industries than the kind accepts, a notification count out of range). `param` names the first offending field and `message` lists every failure. - `409` `LIST_NAME_TAKEN` — `listName` is already used by one of your lists or agents. Pick another name. - `402` `INSUFFICIENT_CREDITS` — The workspace does not have enough credits to start this agent. Nothing was created or spent. - `403` `AGENT_LIMIT_REACHED` — Free-plan accounts may hold at most 10 agents, drafts included. Delete an agent or upgrade the plan. - `404` `LIST_NOT_FOUND` — A source list named in `listId` / `listIds` does not exist or does not belong to the token owner. - `422` `AGENT_SOURCE_LIST_EMPTY` — The source list holds nothing this agent kind can watch — no LinkedIn URLs, no companies, or no trackable contacts. Fill the list first. - `400` `INVALID_REQUEST` — The agents service rejected the request for a reason this API does not model specifically. The request is not retryable unchanged. - `429` `RATE_LIMITED` — The agents bucket is exhausted: 30 requests per minute or 2,000 per day per token owner, shared by every /business/agents operation (a 429 raised by the agents service is relayed with this code too). Retry after the `Retry-After` header. - `500` `UNEXPECTED_ERROR` — The agents service failed (5xx, refused service credential, or a timeout after 60s) or the rate limiter was unavailable. Retry later; quote `request_id` to support. Requires one of the following token scopes: agents. ## Request body - object - `start` boolean: true creates AND activates the agent (spends credits); false (default) saves a draft to activate later. - `listId` string: The existing SOURCE list(s) to watch, by id — the people/companies whose changes are tracked. - `listIds` string[]: The existing SOURCE list(s) to watch, by id: the people whose changes are tracked. Each id is a list id from GET /business/lists. Every list you name is watched and their members are unioned, and there is no cap on how many lists; `listIds` and `listId` are mutually exclusive (sending both is rejected). Unlike the people and companies watchers, this one REJECTS a repeated id rather than collapsing it (422 VALIDATION_FAILED, "listIds must not contain duplicate list IDs"), so name each list once. Only canonical contacts carrying a dataset identity are trackable, so manually created rows are skipped; source lists holding none of them are rejected when the agent starts (422 AGENT_SOURCE_LIST_EMPTY). - `listName` string, required: Name for BOTH the agent and the NEW dedicated results list this watcher creates. Must be unique — never reuse a source list's name; name it after the agent the user is creating. - `maxContacts` integer: Cap on the total number of results this agent delivers into its list. Omit for no cap. - `maxCreditSpend` integer: Maximum credits this agent may spend in a single run or refresh (1000 to 200000); delivery-driven monitors stop once their total delivered results reach it. Omit for no limit. - `enrichPhone` boolean: Also enrich every delivered contact with a phone number. Costs additional credits per contact enriched. - `enrichEmail` boolean: Also enrich every delivered contact with a work email address. Costs additional credits per contact enriched. ## Response `201` Success - object - `agent` object, required - `id` string, required: The new agent's id — pass it as `{agentId}` to every other agent operation. - `type` 'job-changes-watcher', required: The agent kind that was created — always this endpoint's own slug. - `name` string, required: The agent's name, echoed from `listName`; also the name of the results list it delivers into. - `status` 'initializing' | 'processing' | 'active', required: `initializing` when `start` was false (a draft). When `start` was true, the agent's real status right after starting: `processing` while the provider setup and first run are under way, `active` once it is running. - `started` boolean, required: Echoes the `start` you sent: false = a draft that still has to be activated; true = already running and already billing. ## Other responses - `400`: Error - `401`: Error - `402`: Error - `403`: Error - `404`: Error - `409`: Error - `422`: Error - `429`: Error - `500`: Error --- [API](https://skmtc.dev/fuseai/apis/fuse-business-api.md) · [All operations](https://skmtc.dev/fuseai/apis/fuse-business-api/llms.txt) · [OpenAPI document](https://skmtc.dev/fuseai/apis/fuse-business-api/revisions/50d95e0536f4?raw)
