Rather than a standalone tool for sales reps, it targets builders: AI agent teams, sales platforms, ATS and CRM vendors that want to embed prospecting and multichannel outreach into their own products without building the underlying plumbing. The service reports over 50 endpoints, sub-three-second average response times and 99.9% uptime, and it exposes the whole loop - Find, Spot intent, Reach, Reply - through the same API key and request format. The coverage spans four channels: LinkedIn (messages, InMails, invitations, Sales Navigator activity), email (Gmail, Outlook or any SMTP mailbox), WhatsApp (text, files and voice notes) and iMessage (dedicated numbers with tapbacks and read receipts). On the data side it offers a Prospect Data API for people search, full profiles, company data, job postings and funding rounds, plus a Mail API for email verification, discovery and enrichment. An MCP server lets Claude, ChatGPT, Cursor or any MCP client drive outreach directly. Integration options include n8n, Make and Zapier, and LinkupAPI highlights security and compliance as first-class concerns, advertising a zero-storage architecture alongside GDPR and CCPA alignment. A free trial is available, and the product is aimed at teams that already have a user base or agent to plug outreach into. **Pricing & Plans:** LinkupAPI is a paid, credit-based API product. The site advertises a free trial with API keys and usage metered in credits (for example, a send action consuming credits). Exact plan tiers and per-credit pricing are not published on the homepage, so check the pricing page or sales for current numbers. - **One API for four channels:** Send on LinkedIn, email, WhatsApp and iMessage with the same request format, and receive all replies on a single webhook. - **Prospect and company data:** Search people, pull full profiles, company details, job postings and funding rounds as JSON for your product or agent. - **Mail API:** Verify, find and enrich professional email addresses at scale, with real-time deliverability checks. - **MCP server:** Run searches, messages and reply reads from Claude, ChatGPT, Cursor or any MCP-compatible client. - **Automation and compliance:** Native n8n, Make and Zapier integrations plus a zero-storage architecture with GDPR and CCPA alignment. **Strengths:** Single API covering search, messaging, data enrichment and replies reduces vendor sprawl; Strong channel breadth, including iMessage and WhatsApp alongside LinkedIn and email; MCP server enables direct use from mainstream LLM clients; Published performance and compliance posture (99.9% uptime, zero-storage, GDPR/CCPA) **Limitations:** Credit-based usage makes cost forecasting harder without careful monitoring; Homepage does not publish detailed price tiers, so evaluation requires contacting sales or the pricing page; Multichannel outreach at scale carries platform-policy and deliverability risk that users must manage [Profile (Markdown)](https://openaitools.app/tool/linkupapi.md) ## Speechify Speechify is a voice AI assistant built around listening, reading and writing with your voice.
