Deep search costs USD 0.05 a call (USD 20 / USD 0.05 = 400 deep searches). - per-object cap: not applicable | source: [1] - retention: eligible accounts are topped back up to USD 20 each month | source: [1] - egress: not applicable | metered: no | source: [1] - identity: email | detail: the signup form asks for a name, a professional email address and a password, or Google, GitHub or Microsoft sign-in, and a form sign-up is completed from the inbox; a professional email address is credited automatically with no card; any other sign-up is not eligible for free credits by default and adds a card, with no payment required, to unlock them (amount not stated) - interface: rest - limits: - request-rate (binding): USD 20 a month for professional-email accounts; USD 0.005 per standard or fast search with raw results, USD 0.006 with a sourced answer, USD 0.05 per deep search; the API answers 429 when the balance runs out [1] - request-rate (binding): 10 queries a second per organization on search and fetch; x402 requests are limited per IP address instead [2] - binding note: the monthly USD 20 balance, about 4,000 searches, runs out long before 10 queries a second does - interface detail: POST https://api.linkup.so/v1/search with a Bearer API key; fetch, research and tasks endpoints on the same balance; an x402 route takes USD 0.01 a request in USDC on Base with no account or key - endpoint: part of interface detail - tooling: Python SDK (pip install linkup-sdk), JavaScript SDK (npm i linkup-sdk) and a CLI (linkup-search-cli) - composes with: A recurring search leg of about 4,000 raw-result searches a month beside Tavily's 1,000 credits, where the account has a professional email; the x402 route is a paid, account-free fallback at USD 0.01 a request - reliability: an exhausted balance answers 429, the same status as a rate limit; no throttle or ban event recorded - notes: The free balance renews monthly, which sets it apart from one-time signup grants in this class. The pricing page names professional email addresses as the eligible ones. The app tells any other sign-up that free credits are not granted by default and that adding a card, with no payment required, unlocks them; the amount unlocked, and whether the monthly top-up then applies, is not stated. An archived copy of the pricing page from June 2026 states the credit with no email condition, and one from August 2026 states it for professional email addresses. The x402 route bills a flat USD 0.01 a request on search and fetch. - evidence note: the monthly top-up, the per-call prices, the rate limit and the no-card statement are quoted from first-party pages; no keyed search was made, so the read path is unprobed; the app's own text says only organizations signed up with a professional email address are eligible for free credits by default and that other sign-ups add a card, with no payment required, to unlock them; the amount a webmail account receives after that step is behind a sign-up and a card, so it is unverified - evidence: - [1] 2026-10-30: USD 20 on signup with a professional email, topped back to USD 20 monthly | capture: sha256:55ce46f7125d6cc9dd137136e0af02ec96a53561afc083da27138c8d53c5b679 | quote: When you first sign up with a professional email address, your account is automatically credited with \$20.
