Start a paid job billed to the user's Desearch balance: find people on X, YouTube, LinkedIn, or TikTok who match a plain-language description. Each person comes back with a fit score, why they matched, their audience, and public contacts and links. This call reserves count times the platform's per-person price (reserved_cost_usd) and returns a task_id at once. When the search ends you pay only for the people it delivered (a per-search minimum applies when it finds anyone; a search that finds no one is free) and the rest of the reservation is returned. The search runs in the background, usually for 1 to 5 minutes: poll people-search-status with the task_id to read progress and the people found so far, and use people-search-control to pause, resume, or cancel it. Do not start the same search twice; send idempotency_key so a retry returns the first task instead of charging again. Filters depend on the platform. x: min_followers, max_followers, verified_only, countries, keywords, exclude_keywords. youtube: min_subscribers, max_subscribers, countries, require_contact, keywords, exclude_keywords. linkedin: min_followers, max_followers, countries, keywords, exclude_keywords. tiktok: min_followers, max_followers, require_contact, keywords, exclude_keywords.
