## Linked API

Linked API is built for teams that need programmatic control over LinkedIn activity but cannot rely on LinkedIn's own restricted partner APIs. Every action runs inside a dedicated cloud browser instance matched to a single LinkedIn account, using human-like pacing and typing rather than headless scripts or raw HTTP requests. That architecture is the core of its positioning: you get structured JSON results back while the actual interaction happens in a real browser session tied to your own login.

On top of the raw actions sits a workflow layer. Calls can be chained with conditional branches up to several levels deep, which makes multi-step pipelines practical — search companies, filter by size and industry, extract employees, qualify by position, then export or push into a CRM. The same action set is exposed across REST, an official Node.js SDK, a CLI tool, an MCP server and agent skills, so agents built on Claude, ChatGPT, Cursor, Windsurf or similar environments can call LinkedIn operations as native tools.

Commercial terms are per-seat: one seat equals one LinkedIn account. A 7-day free trial leads into monthly or annual plans with unlimited workflow execution, and a higher tier adds Sales Navigator actions. The company is explicit in its documentation that increasing account safety depends on human-like pacing and user-configured rate limits, and that most account issues stem from spam-like behavior.

**Pricing & Plans:** Per-seat subscription with a 7-day free trial. Core is about $49 per seat/month for individuals and small teams; Plus is about $74 per seat/month and adds Sales Navigator actions. Annual billing saves roughly 29%. One seat equals one LinkedIn account, with unlimited workflow execution and volume discounts available on request.

- **50+ LinkedIn actions:** Send messages, connection requests, reactions and comments, and run people or company searches — chained into conditional workflows up to five levels deep.
- **Structured data extraction:** Search companies and people with advanced filters, pull employee lists, enrich profiles and return clean JSON for your CRM or data warehouse.
- **Dedicated cloud browser:** Each account runs in its own cloud browser with a matching device profile, human-like timing and custom mouse/typing behaviour.
- **Built for AI agents:** An MCP server, agent skills, CLI and official Node.js SDK let assistants in Claude, ChatGPT, Cursor and similar tools call LinkedIn operations directly.
- **No-code and dev integrations:** Native connectors for n8n and Make plus plain HTTP endpoints mean the same workflows are reachable from any language or automation stack.

**Strengths:** Structured REST API plus official Node.js SDK, CLI, MCP server and agent skills; Dedicated cloud browser per account instead of shared or headless infrastructure; Unlimited workflow execution on both paid tiers, with no usage caps on actions; Native n8n and Make integrations for teams that prefer no-code

**Limitations:** It is an independent, unofficial tool — LinkedIn does not authorize this kind of account automation; Per-seat pricing tied to LinkedIn accounts can get costly across large teams; Sales Navigator actions require the more expensive Plus tier

## Success.ai

Success.ai is a B2B sales platform built around an AI-assisted prospecting and outreach workflow. Its core promise is simple: give sales teams and agencies access to a large contact database and the sending infrastructure to reach those prospects at scale. The platform advertises unlimited access to 700M+ verified contacts, including email addresses and phone numbers, along with buyer intent data to target prospects showing real interest signals.

Beyond the database, Success.ai bundles the outreach stack many teams otherwise assemble from several tools. You can connect unlimited email accounts, run email warmup to keep messages out of spam, and manage responses from a single unified inbox. Multichannel sequences let you reach prospects over email, LinkedIn, or phone within one campaign, and a kanban-style CRM tracks deals. An AI writer personalizes messages at scale in more than 100 languages.

Success.ai also offers custom and agency-oriented options such as done-for-you email account setup, white-label and agency features, and dataset products covering public LinkedIn profiles, company profiles, and employee records. It advertises a free signup with a clear upgrade path to paid plans for unlimited access, and the site is protected by a bot challenge, so automated previews may fail even though the product is active. It is an independent commercial product, not affiliated with any email or social platform it connects to.

**Pricing & Plans:** Freemium with a free account signup and paid plans for unlimited access; exact prices are shown on the Success.ai pricing page and a demo can be booked.

- **B2B lead database:** Lead Finder gives unlimited access to a database of 700M+ buyer emails and phone numbers, with search and targeting tools.
- **Buyer intent data:** Follow active buyers using interest signals based on specific topics or keywords, so outreach targets prospects showing real intent.
- **Email finder and enrichment:** Verify and enrich emails and phone numbers, and clean your lists before you start a campaign.
- **Unlimited email outreach:** Connect unlimited sending accounts, use email warmup to protect deliverability, and manage replies in one unified inbox.
- **AI writer and sequences:** An AI writer personalizes emails at scale in more than 100 languages, and multichannel sequences combine email, LinkedIn, and phone from one campaign.

**Strengths:** Large verified B2B contact database with intent data; All-in-one outreach: sending, warmup, inbox, and sequences; AI personalization in 100+ languages and agency/white-label options

**Limitations:** Homepage enforces a bot challenge, so some crawlers and previews may fail; Full unlimited access requires a paid plan; Effectiveness depends on list quality and deliverability setup
