## LinkupAPI

LinkupAPI positions itself as "the outreach API for AI agents and software." 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

## Miligram

Miligram positions itself as "contact intelligence for AI agents." Instead of working inside yet another standalone prospecting dashboard, you install a single connector into the AI tools you already use — Claude or ChatGPT — and then ask natural-language questions such as "How do I reach the founder of this company?" or "Find the team at this firm." The assistant calls Miligram's tools behind the scenes and returns sourced emails and direct phone numbers.

Under the hood there are two capabilities: a people-search function that surfaces everyone at a given company or domain, and a lookup function that resolves real emails and phone numbers for the names you care about. Every result carries a confidence mark, and the company says you are only charged when it actually finds something. This pay-for-results model plus a low entry price are the core of its pitch against larger sales-intelligence incumbents.

Pricing starts with ten free contacts and no credit card, then a Pro plan aimed at solo users who need a steady monthly volume of verified contacts, with an Enterprise tier for teams running bulk outreach, shared seats, priority throughput and SLAs. Note that Miligram is an independent product and is not affiliated with, endorsed by, or produced by Anthropic or OpenAI, even though it integrates with their assistants.

**Pricing & Plans:** Freemium. Start with 10 free verified contacts (no card required). Pro is $9/month for 250 verified contacts, emails and direct phone numbers, company-wide people search and access from Claude and ChatGPT. Enterprise pricing is custom, with high-volume bulk lookups, team seats, priority throughput and SLAs. You only pay when a contact is found.

- **Works inside Claude and ChatGPT:** Add one connector and query it in plain language from the AI assistant you already use — no separate app to learn or keep open.
- **Verified emails and direct phone numbers:** Results come back with sourced work emails and direct dial numbers rather than generic switchboard lines, each flagged with a confidence mark.
- **Company-wide people search:** Point it at a company or domain to surface the full roster — founders, partners, decision-makers — then resolve contact details for the whole team in one pass.
- **Pay only for what is found:** Billing is tied to successful lookups, so failed searches do not consume your contact quota.
- **Low-cost entry pricing:** A $9/month Pro tier undercuts typical seat-based sales-intelligence tools, with a 10-contact free trial before you commit.

**Strengths:** Runs inside Claude and ChatGPT, so there is no new dashboard to adopt; Charges only when a contact is actually found; Very low entry price compared with seat-based sales-intelligence tools; Company-wide search resolves a whole team in a single call

**Limitations:** Monthly contact volume on the entry tier is modest for heavy users; Verification quality ultimately depends on source coverage, which can vary by region; Bulk and team workflows require a custom Enterprise conversation
