### `check_link_in_bio_and_newsletter` (~1181 tokens)

Check a Link in Bio Page for a Newsletter

Follows the link in bio page behind a creator handle, or a link in bio URL you already hold, and reports whether the creator runs a newsletter, which email platform hosts it, and the page URL that proves it. Also returns the link in bio host, the creator's own website resolved through any redirect, every outbound link found, the public business email, a manager or booking email with the page it came from, a matched talent agency name and domain, and what the creator sells: course, coaching, digital product, merch, membership, brand deals, and discount codes. Every row carries newsletter_check_method, row_status, and error_reason, so a no is told apart from an unknown. Charges $0.002 per run plus $0.008 per creator checked, and on top of that $0.004 per headless browser render, $0.005 per website email scan, $0.003 per agency match, and $0.01 per Instagram bio fetch, each only when that step runs. The AI check uses your own Anthropic or OpenAI key and is billed by them, not here. Contributes the public records it finds to a shared creator and agency pool that all users of this actor read from, so a later run reads what this one found; `contribute_to_shared_pool` is on by default and turning it off leaves the run reading the pool and writing nothing. Only public data already in the returned rows is contributed, nothing from your Apify account or your input, and a contribution is not charged. Requires an APIFY_TOKEN and consumes Apify credits. Read only.

Input parameters:

- `ai_api_key` (string): Your own model API key. Used only when `ai_check` is on. Never stored, logged, or written to a row.
- `ai_check` (boolean): Off by default. When on, a model reads the rule classifier's evidence and rules on each row. Runs only with your own key in `ai_api_key`; the actor never uses a Mamba Labs key and never logs yours. D…
- `ai_provider` (string): Which API the key belongs to. Default: "anthropic".
- `batch_size` (integer): Rows fetched at once. Leave empty for the measured per platform default; the measurement is in the README. Higher is faster and, above the measured point, loses rows.
- `bio_links` (array): Skip the profile read and start from these pages directly (a Linktree, Stan Store, linkin.bio page, or the creator's own site). One per line. When one input item carries both a handle and bio links,…
- `contribute_to_shared_pool` (boolean): On by default. Contributes the public records this run finds to a shared creator and agency pool that all users of this actor read from, so a later run reads what this one found. Only public data alr…
- `escalate_on_block` (boolean): On by default. A profile fetch that comes back as a bot detection page is retried once over the residential proxy. On Instagram the bio, bio link, and following are read from the profile page over re…
- `handles` (array): One per line. A profile URL on any supported platform (https://www.tiktok.com/@name, https://www.instagram.com/name/, https://www.youtube.com/@name, a Pinterest, Twitch, or Threads profile, an Apple…
- `match_agencies` (boolean): Matches the domain of a manager or business email against the bundled talent agency list and fills agency_name, agency_domain, and agency_match_method. Charged per matched row (event agency-match). D…
- `platforms` (array): Which platforms a bare @handle is looked up on. A full profile URL carries its own platform and ignores this. This actor does not search; pass the creators you want read. Supported: TikTok, Instagram…
- `render_unreadable_pages` (boolean): Off by default. Some link-in-bio pages (Stan Store, linkin.bio, Typeform shells) return an empty shell to a plain fetch and are classified unknown_fetch_failed. Turn this on to render them in a headl…
- `scan_website_for_email` (boolean): Off by default. For creators with their own website (not a link-in-bio page), reads the home, contact, and about pages and the footer for an email and records where it was found. Charged per creator…
