That graph is exposed two ways: a flexible REST API with a filter language that supports intent-style queries, and an MCP server that drops the whole graph into an agent in a single line of configuration. Teams use it for search, enrichment, signals and watchers — the four primitives that cover most B2B data workflows. The product is built around three claims it calls freshness, depth and resolution. Freshness means profiles are re-verified continuously instead of going stale; depth means a profile carries the whole story — role changes, funding events, hiring activity, open-source work — rather than a single row; resolution means every identity is mapped to the right human, which is the hardest part of B2B data and the reason agents so often sound confidently wrong. Crustdata markets itself chiefly to sales, recruiting and investing teams that now run sourcing flows end to end with agents. Technically, queries are expressed as structured filter conditions over fields such as headcount, headcount growth over twelve months, total funding raised and country, and return records with company name, website, funding and headcount. Because agents do the querying, the interface avoids filter menus and list limits — you describe the target in natural language and the agent translates it into precise filters. **Pricing & Plans:** Crustdata does not publish public list prices; pricing is arranged with the sales team based on use case and volume. A demo request and API key flow are available from the site. - **Live graph of 1B people and 100M+ companies:** Every indexed web page is parsed and resolved into a single graph of people and companies that is re-verified continuously instead of archived. - **REST API with intent-style filters:** Compose structured conditions over headcount, headcount growth, funding raised, locations and more, with no filter menus or fixed list limits. - **MCP server for agents:** Drop the entire graph into an AI agent with a one-line MCP configuration so it can search, enrich and monitor without bespoke integration code. - **Signals and watchers:** Track role changes, funding events and hiring activity on the accounts and people you care about, so agent workflows act on what changed rather than what was true last quarter. - **Identity resolution:** Multiple sources are mapped to the right individual, reducing the duplicate and mismatched profiles that make agent output unreliable. **Strengths:** Very large, continuously refreshed graph spanning people and companies; Both REST API and MCP, so it works for classic backends and for agents; Intent-based querying removes the filter-menu and list-limit constraints of typical B2B tools; Strong emphasis on fresh signals — role changes, funding, hiring — not just static firmographics **Limitations:** No public pricing, so evaluation requires a sales conversation; Credit-based or volume-based structures can make cost hard to model up front; Resolving identities perfectly across the open web remains inherently imperfect [Profile (Markdown)](https://openaitools.app/tool/crustdata.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/linkupapi.md) ## Frequently Asked Questions ### How do Crustdata and LinkupAPI compare in monthly traffic?
