Does Explorium have an MCP server?

Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.

What is Explorium's data accuracy?

Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.

What is Explorium's API rate limit?

The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.

Does Explorium offer a free trial?

Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.

What is Explorium's data refresh rate?

High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.

How does Explorium compare to ZoomInfo or Apollo for coverage?

Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.

Is Crustdata a prospecting tool or a data infrastructure API?

Crustdata is fundamentally an API-first data infrastructure platform — not a traditional prospecting tool with a search UI. It is designed for developers and data engineers building products or workflows that need programmatic access to real-time company and people data. There is no built-in list-builder or export workflow for non-technical users. If your team needs a no-code prospecting interface, Crustdata should be integrated as the backend data layer of another tool.

What makes Crustdata's data different from static B2B databases?

Crustdata aggregates data continuously from live sources — LinkedIn, SEC filings, funding databases, Glassdoor, G2, web traffic services, and news aggregators — rather than relying on periodic database refreshes. This means company signals like headcount changes, executive moves, and funding announcements are available in near real-time via webhooks, rather than weeks or months later. The platform also offers a Web Search API that surfaces fresh, structured web documents on companies and people for LLM-ready intelligence.

What kinds of signals can I monitor with Crustdata webhooks?

Crustdata webhooks can notify your system in real time when tracked companies experience key events: funding announcements, headcount growth or decline (by department), executive hiring or departures, new job openings, product launches, significant news mentions, and web traffic changes. This enables trigger-based outreach — for example, automatically queuing an account for outreach the moment they raise a Series B or hire a new VP of Sales.

How does Crustdata compare to People Data Labs or Clearbit for API use cases?

Crustdata differentiates from People Data Labs (PDL) and Clearbit primarily through its depth of company growth signals and its explicit focus on AI-agent use cases. While PDL and Clearbit are strong for bulk contact enrichment and firmographic append, Crustdata layers on time-series headcount data, funding signals, web traffic trends, and a Web Search API — making it more suitable for dynamic, signal-driven workflows than static enrichment pipelines. Crustdata is also a newer, smaller company with less established enterprise support infrastructure.

Can Crustdata be used to find email addresses and phone numbers for outreach?

Crustdata's primary focus is company intelligence and people profile data — not deliverable email and phone lookups for cold outreach. While people profiles contain contact signals and professional information, Crustdata is not optimized for direct-dial or verified email delivery at the level of tools like UpLead or Apollo. Teams building AI outreach tools on Crustdata typically combine it with a contact data provider for verified emails and phone numbers.

What is Crustdata's Y Combinator backing and what does it mean for the product?

Crustdata is part of Y Combinator's Fall 2024 (F24) batch, having been founded in 2023 by Chris Pisarski, Abhilash, and Manmohit Grewal. The YC backing validates the team and mission but also reflects the company's early stage — it is still building out enterprise-grade support, compliance documentation, and product maturity. The YC network provides access to a relevant customer base of AI-native startups, which aligns well with Crustdata's positioning as infrastructure for AI agents.

Does Crustdata have a Claude Code Skill or Claude Plugin?

Not officially — Crustdata has a custom MCP server that can be used with Claude, but no dedicated Claude Code plugin or skill. If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.

How much does ZoomInfo cost?

ZoomInfo does not publish pricing. Entry-level contracts typically start at $15,000–$25,000/year, with average contract values around $31,000/year. All plans require annual commitments. Contact their sales team for a custom quote.

Does ZoomInfo offer a free trial?

No. ZoomInfo does not offer a free trial. They offer a free demo and limited free searches upon account creation, but the full platform requires an annual contract.

How large is the ZoomInfo database?

320M+ professional contact profiles, 100M+ company profiles, 65M+ direct dials, and 150M+ direct emails across 195+ countries. Strongest accuracy in North America, UK, India, and Canada.

Is ZoomInfo GDPR compliant?

Yes. ZoomInfo holds TRUSTe GDPR and CCPA validations, ISO 27701, ISO 27001, and SOC 2 Type II attestation. They operate a proactive notice program and are registered as a data broker in California and Vermont.
