Launch outreach campaigns directly from your product.

Run multi-step LinkedIn outreach campaigns. Connect accounts, launch sequences, and track results in real-time.

Find the email. Send it. Same API.

Find and verify a prospect's work email from a LinkedIn profile, then send from your users' own Gmail or Outlook mailboxes. Replies and bounces come back by webhook.

Unlimited accounts. One fixed price.

Connect as many LinkedIn, email and WhatsApp accounts as your users bring. You pay for credits, never per seat, and the bill never goes above $3,000 a month.

Per-seat tools at $5 per connected account per month, the cheapest rate we found. LinkupAPI shown on the Unlimited plan.
Unlimited connected accounts
LinkedIn, email and WhatsApp. Your users bring as many as they want.
$0
Per extra account
You pay for the actions you run, not for seats. Adding an account costs nothing.
$3k
Maximum monthly bill
The top plan is $3,000 a month with unlimited credits. Above that, the price stops moving.

Your accounts stay safe.

Getting banned is the real cost of outreach. Every account connected through LinkupAPI gets its own infrastructure and is treated like a person, not a bot.

100% cloud-based

No browser extension, nothing installed on your users' machines. LinkupAPI runs server-side and talks to LinkedIn the way a real user does.

no extension to detect
Dedicated proxy per account

Every account gets its own residential or ISP IP, pinned near its real location and never shared with another account. Bring your own proxy if you prefer.

country-matched IP
Same device, every call

The session is bound to a single device signature and replayed on every request, like a real user on their own machine.

device-bound sessions
Monitoring, not arbitrary caps

We don't impose blind daily limits. We track every account's activity and health, and alert you the moment one gets flagged, so you can slow down before it costs the account.

alerts, not caps

MCP-first. Plug LinkupAPI into Claude, ChatGPT or Gemini in one click.
