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) ## Treg Treg acts as a unified credential and routing layer for AI agents. Instead of signing up for dozens of SaaS APIs, you connect your agent to one MCP server and receive a single treg token that answers for every tool in the catalog. The catalog spans SEO keyword and rank tracking, backlink analysis, AI search visibility, social media and advertising data, lead enrichment, email verification, company data, web scraping, and AI video, image, and voice generation. A core idea is evidence-based tool selection. Multiple providers often sell the same capability - nineteen sell backlinks, nine sell email lookup - so treg shows each one's listed price alongside measured success rate, speed, and last-answer time, letting the agent pick a vendor on data rather than guesswork. Pricing is pay-per-result with the cost quoted before each call, funded by a starting balance, and there is no subscription required for tools you'd otherwise buy seats for. For teams that already pay providers directly, treg supports bring-your-own-key (BYOK): your own keys route first and run unmetered, while credentials are injected server-side so raw keys never sit on a machine. It is fully open source under Apache 2.0, integrates with coding agents and automation workflows, and lets orgs publish internal SKILL.md-based tools to teammates by token. **Pricing & Plans:** Pay-per-call with no subscription; prices are quoted before each call and start with $1.00 of free credit. Bringing your own provider keys makes those calls unmetered. - **One key, 127 providers:** A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files. - **Evidence-based provider comparison:** See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want. - **Pay-per-call pricing:** Pay fractions of a cent per call with the price shown before you commit, no monthly seats required. - **Bring your own keys (BYOK):** Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine. - **Open source and agent-ready:** Apache 2.0 licensed with MCP support, coding-agent integration, and the ability to publish your own SKILL.md tools. **Strengths:** Single key across 4,100+ endpoints and 127 providers; Transparent pay-per-call pricing quoted before each call; Measured success rate and latency help pick the right vendor; Open source (Apache 2.0) with BYOK and server-side credential injection **Limitations:** The breadth of the catalog can be overwhelming for newcomers; Coverage and reliability depend on the many third-party providers behind it; Usage is metered, so heavy callers still accumulate real costs [Profile (Markdown)](https://openaitools.app/tool/treg.md) ## Frequently Asked Questions ### How do LinkupAPI and Treg compare in monthly traffic?
