BlitzAPI Review

BlitzAPI takes the flat-rate approach to B2B data: instead of buying credits per lookup, you pay a fixed monthly price for unlimited API calls against its database of 360M+ contacts and 60M+ company profiles. That pricing model is the headline difference from per-credit incumbents, and it changes the economics for teams running high-volume enrichment inside Clay tables, n8n flows, or custom scripts.

Key Features

• People search that returns decision-makers ranked and prioritized for your ICP
• Email enrichment against 62M+ verified addresses, with a claimed 97% accuracy
• Catch-all validation in real time, with claimed >98% accuracy — useful for rescuing leads other verifiers mark risky
• Phone enrichment from 40M+ mobile numbers (US coverage only)
• Company enrichment with firmographics, plus LinkedIn profile matching
• Unlimited API calls at 5 requests per second on every plan

It plugs into Make, Zapier, n8n, Clay, Salesforce, HubSpot, Airtable, and Google Sheets, and the API-first design means anything with an HTTP client can use it. Data is publicly sourced and GDPR-compliant, per the vendor.

Pricing

Three flat tiers: Unlimited Leads at $399/month (contact and company data), Unlimited Email at $499/month (adds the email finder), and Unlimited Phone Numbers at $599/month. Signup includes 1,000 free credits to test before committing.

Who It's For

Growth, RevOps, and GTM engineering teams doing enough volume that per-credit pricing hurts — think automated enrichment pipelines rather than one-off list building. Low-volume teams will find per-credit tools cheaper; the flat rate only wins once you're enriching at scale.
