Build recruiting automation systems on top of a premium B2B data layer. Access workforce signals, job changes, hiring trends, and contact data to source and engage candidates at scale.
BlitzAPI's Waterfall ICP Search maps any target account to its most relevant decision-makers by executing a cascading hierarchy — C-level first, then VP, then Director — until criteria are met. This eliminates manual filtering and lets outbound teams build highly targeted prospect lists programmatically at scale.
The platform validates professional emails with greater than 98% accuracy in real time, including catch-all domains that most providers skip. Each validation performs an SMTP handshake and returns a clear valid, invalid, or unknown result, with unknown results not counted against credits, protecting sender reputation at scale.
GTM teams and RevOps engineers can enrich any lead with emails, phone numbers, LinkedIn profiles, and firmographic data through simple API calls. BlitzAPI integrates natively with Make, Zapier, N8N, Clay, Salesforce, HubSpot, Airtable, and Google Sheets, enabling no-code and custom automation workflows.
Findymail verifies every email address before charging for it, guaranteeing a bounce rate below 5% — well under the 10% threshold that triggers domain reputation damage. Teams sending at high volume can protect sender reputation while maintaining find rates that competing tools miss.
The Findymail Chrome extension automates bulk export from LinkedIn Sales Navigator, extracting verified email addresses for entire search result pages in minutes. Exported contacts include a keyword-match flag showing whether the lead matches custom search filters.
Findymail is frequently used as a secondary or tertiary enrichment provider in waterfall sequences alongside tools like Prospeo and Datagma. Its high precision at the verification stage catches valid emails that other tools flag as unverifiable, pushing combined find rates to 85–92%.
Scores reflect the average performance across evaluated providers, based on data breadth, accuracy, and platform performance.

Explorium
Sales Director, B2B Technology Company
"LeadMagic has the best price of the market and the quality is very good. The most accurate contact data I have found — and we have used them all: Leadfeeder, Lusha, ZoomInfo, Slintel to mention a few. Quality of data is amazing; within minutes I can find and call people and it's exactly what I need."
Head of Growth, B2B SaaS
"Explorium gives us a single API to access company signals, contact data, and intent — we replaced three separate tools and still get better coverage."
"No public reviews available yet on G2 or similar platforms."
Founder, Cold Email Agency
"Findymail is the best email finder out there. I send 7 million cold emails per month and have tested over a dozen email finders. Findymail consistently delivers the highest accuracy — I have never had high bounce rates since switching to it. The accuracy and coverage of the data available addresses my need for precise and comprehensive information when finding and verifying emails."

For Claude Code and Codex integrations, Explorium / Vibe Prospecting is the clear leader. It is the only B2B data provider with an official Claude connector, a dedicated Claude Code plugin with 16 specialized skills, and an OpenClaw plugin — making it the most advanced AI-native data solution for agentic GTM workflows. The Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) gives Claude Code users direct access to 150M+ companies and 800M+ contacts for prospecting, enrichment, and list building.
LeadMagic provides 16 MCP (Model Context Protocol) tools that connect its enrichment endpoints directly to AI environments including Claude Desktop, Claude Code, Claude.ai, and Cursor. Once configured with your LeadMagic API key, you can ask the AI assistant to look up a contact's email, enrich a company record, or identify website visitors in natural language — and the AI will call the appropriate LeadMagic API endpoint, return the result, and incorporate it into the conversation. This enables conversational B2B data enrichment without writing code or switching to a separate interface.
On the Basic plan ($59.99/month, 2,500 credits), unused credits expire at the end of each billing cycle. On the Essential plan ($99.99/month, 10,000 credits) and all higher tiers, unused credits roll over indefinitely with no expiration date. For teams with variable enrichment volume — such as those running large campaigns in some months and minimal enrichment in others — the Essential plan's rollover policy can provide significantly better value despite its higher nominal price.
LeadMagic is accessible as a native data provider within Clay, where it powers email finding, phone enrichment, company data, and visitor identification directly within Clay table workflows. When accessed via Clay's managed integration, enrichment costs 6 credits per enriched cell (reflecting Clay's coordination layer). LeadMagic is rated as the top enrichment provider in Clay's marketplace based on community reviews, primarily due to its accuracy-to-cost ratio — teams using LeadMagic via Clay report finding valid data at a significantly lower cost per result compared to other providers in the same marketplace.
LeadMagic states 97% email accuracy and a under-2% bounce rate, achieved through a five-step verification pipeline: syntax check (format validation), DNS validation (domain exists and has valid MX records), SMTP handshake (mailserver accepts the email), mailbox validation (address-level existence check), and risk scoring (spam trap and disposable email detection). Every email that passes this pipeline is returned as verified; any email that fails any step is returned as invalid and no credit is charged. The stated 75–85% accuracy range for US and European contacts in independent assessments reflects the real-world find rate, not the accuracy of emails that are returned.
LeadMagic's visitor identification product de-anonymizes company-level website traffic — it reveals which companies are visiting your website, not individual visitor identities. For each identified visit, it surfaces company name, industry, headcount, company website, and a link to matching contacts in LeadMagic's enrichment database so you can identify decision-makers to contact. It does not identify individual visitors by name or personal data. The signal is most useful for account-based sales and marketing teams that want to prioritize outreach to companies already showing active interest in their product.
Not officially — LeadMagic 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.
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.
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.
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.
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.
High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.
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.
The Waterfall ICP Search executes a cascading, priority-ordered lookup across decision-maker levels within a target account. Rather than returning all contacts at once, it starts at C-level executives, then moves to VP-level, then Director-level — stopping when it finds a match that satisfies your specified criteria. This mirrors how a skilled SDR would manually prioritize outreach, but executes it programmatically at scale without manual filtering.
Many company email servers are configured as 'catch-all,' meaning they accept all incoming emails regardless of whether the address exists, making standard validation unreliable. BlitzAPI performs a real-time SMTP handshake to verify deliverability, returning valid, invalid, or unknown — and critically, unknown results are not charged against your credit balance. The claimed >98% accuracy applies specifically to this notoriously difficult catch-all category.
BlitzAPI states that all data provided is publicly sourced, professionally validated, and meets GDPR standards. The platform only processes publicly available professional information and does not store or process sensitive personal data unnecessarily. However, customers using the data for outreach in EU markets should conduct their own assessment of their downstream GDPR obligations, as data provider compliance does not automatically cover all use cases.
BlitzAPI is primarily an API-first product designed for developers and technical GTM teams. There is no native prospecting UI or dashboard. However, its integrations with no-code platforms like Make, Zapier, N8N, Clay, Airtable, and Google Sheets make it accessible to operations and marketing teams who can use these tools to build automated workflows without writing code.
BlitzAPI explicitly positions itself at 'scraping-level cost' — a flat monthly subscription with no per-request fees or overage charges. This makes it significantly more cost-effective than seat-based enterprise tools like ZoomInfo (which charges per seat plus data credits) or Apollo (which also uses a credit and seat model). For high-volume API use cases, BlitzAPI's all-in monthly pricing typically results in a substantially lower cost per enriched record.
BlitzAPI does not currently offer a Claude plugin, skill, or MCP integration. 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.
Catch-all domains are configured to accept all inbound email regardless of whether the specific address exists, which makes standard SMTP verification unreliable. Findymail uses a proprietary catch-all recovery algorithm that goes beyond basic SMTP checks — testing email pattern consistency, cross-referencing public sources, and applying confidence signals — to classify catch-all addresses as deliverable or risky. Addresses classified as risky catch-alls are not returned as verified, protecting your sender reputation.
Findymail's pricing model is designed to align cost with value: you only pay when a deliverable email address is actually returned. If Findymail cannot find or verify an email for a contact, no credit is deducted. This model means there is no penalty for searching against contacts who have no discoverable email, and it incentivizes Findymail to maximize verification accuracy rather than simply maximizing output volume.
In single-provider mode, independent benchmarks place Findymail's email find rate at approximately 75%, which is lower than database-heavy tools like Apollo or Hunter but with substantially better deliverability on the emails it does find. In waterfall setups — where Findymail runs after one or two other providers to catch emails they missed or mis-classified — combined find rates reach 85–92%, while the overall bounce rate of the waterfall stays low because Findymail's verification is the final quality gate.
Unused credits roll over to the following month on all paid plans. However, your total credit balance is capped at 2× your monthly plan size. For example, on the Starter plan (5,000 credits/month), your maximum accumulated balance is 10,000 credits. If you consistently use fewer credits than your plan provides, you will eventually hit the cap and excess rollover will be forfeited, which is worth factoring into plan selection for teams with irregular outreach volume.
