# List signals

> Every signal definition on the account, across all kinds, with its id, kind, name, whether it is enabled, a one-line summary of what it watches, when it last swept, and how many lead generation programs run it. Kinds: linkedin_content, news_content, job_posting, page_follower, new_hire, past_company_move, deal_stage_lookalike and agent. Each has a create operation here except agent, which Tamtam sets up. A shallow overview: [List LinkedIn content signals](/api-reference/linkedin-content-signals/list-linkedin-content-signals) reads that kind's full configuration.
