BlitzAPI
Prospecting data over a plain HTTP API. No dashboard, just endpoints your workflows call.
In our stackLast reviewed July 17, 2026
What BlitzAPI actually is.
BlitzAPI is a B2B data API: people search, company search, email finding, and phone number lookup, all called over plain HTTP endpoints. There's no dashboard to log into. You write the integration yourself, or wire it through Clay, Make, n8n, or Zapier, and pull records straight into whatever pipeline you're already running. It's built for teams who'd rather call an endpoint than click through a UI.
The tradeoff is cost and coverage. Every tier is a flat monthly subscription rather than pay-per-use, so a team just testing the data pays full price from day one. Phone number lookups only cover US mobile numbers, nothing international. And every plan shares the same rate limit, so a high-volume enrichment run has to be paced rather than fired off all at once.
What it does
- Searches people across 380M+ contacts and 60M+ company profiles.
- Verifies emails at a claimed 97% accuracy across 62M+ addresses.
- Looks up US mobile numbers from a 40M+ record pool.
- Runs as a pure API call, no dashboard or UI.
- Plugs into Clay, Make, n8n, Zapier, Salesforce, HubSpot, Airtable, and Google Sheets.
- Caps every plan at 5 requests per second.
- Offers catch-all email validation as an additional capability.

Pricing, without the fiction.
From the BlitzAPI pricing page · verified July 17, 2026
- Unlimited leads
- Unlimited companies
- Access to 380M+ contacts
- Access to 60M+ companies
- 5 requests per second
- Everything in Unlimited Leads
- Unlimited email finder
- 62M+ verified emails
- 97% email accuracy
- Everything in Unlimited Email
- Unlimited phone numbers
- 40M+ mobile phone numbers
- US coverage only
The bill is driven by which flat-rate tier you pick, not by usage within that tier: $399/month for unlimited leads and company search, $499/month to add an unlimited verified email finder, and $599/month to also add unlimited US mobile phone numbers. Because each tier is "unlimited" rather than metered, the real cost driver is which data type you need (leads vs. email vs. phone) rather than volume - a team that only needs company/person search overpays by jumping straight to the phone tier. The 5 requests/second cap across all tiers is the practical ceiling to check against your expected enrichment volume before assuming "unlimited" means no bottleneck.
Choose it, or skip it.
Choose it if
- Teams with an engineer or ops person who can call an API or wire it into Clay, Make, n8n, or Zapier - this is not a point-and-click tool.
- Teams that want a flat monthly bill instead of pay-per-credit pricing - once you're on a plan, endpoints are unlimited with no per-request charge.
- Teams already doing outbound at volume who are tired of stacking Apollo + a phone-number vendor + an email finder separately - BlitzAPI bundles people search, email finding, and phone numbers under one subscription.
- Clay users specifically - there's a documented BlitzAPI + Clay setup for finding decision-makers and their contact info inside a Clay table.
Skip it if
- Non-technical teams or solo founders who want a UI to click through - there's no dashboard-first workflow shown; the product is built around API calls and docs.
- Teams needing phone numbers outside the US - the phone plan's 40M+ mobile numbers are US-only coverage.
- Low-volume users - the plans start at $399/month flat, which is a lot to commit to if you only need a few hundred contacts a month.
If not BlitzAPI, then what.
- Apollo.iofree tier (no card) + paid plans from ~$49-59/mo/user (annual billing)
Choose Apollo.io when your team wants a full UI with built-in sequencing and doesn't want to build against an API to get search and enrichment.
- FullEnrichcredit-based; from $55/mo at 1,000 credits
Choose FullEnrich when you want waterfall enrichment across many providers with pay-as-you-go credits instead of a flat monthly unlimited plan.
- Prospeofree tier (100 credits/mo) + paid plans from $37/mo per user yearly (2,000 credits/mo on monthly billing)
Choose Prospeo when you mainly need email and phone finding at lower monthly commitment levels than BlitzAPI's $399+ tiers.
Asked in real client work.
How does the pricing actually work - credits or unlimited?
It's a flat monthly subscription per tier ($399, $499, or $599 depending on plan), and once you're subscribed every endpoint on that plan is unlimited with no per-request or overage fee. Free trial credits (1,000 per the pricing page, though some pages cite 100) let you test before buying.
What's the difference between the three plans?
Unlimited Leads ($399/mo) covers people and company search across 380M+ contacts and 60M+ companies. Unlimited Email ($499/mo) adds a verified email finder claiming 97% accuracy across 62M+ verified emails. Unlimited Phone Numbers ($599/mo) adds 40M+ US mobile numbers on top of the email tier.
Is the phone number coverage global?
No. The Unlimited Phone Numbers plan is explicitly US-only for its 40M+ mobile number dataset.
What's the rate limit?
5 requests per second across all tiers, per the pricing page - worth checking against your expected send/enrichment volume before committing.
Do I need to build custom code, or can I use no-code tools?
BlitzAPI is API-first and aimed at technical teams, but the vendor documents direct integrations with Clay, Make, n8n, Zapier, Airtable, Salesforce, HubSpot, and Google Sheets, so a no-code builder can wire it in without writing a full backend.
