# Blitz API review (2026): fast, precise, and unlimited, but it finds less By [Florian Martens](https://pipe0.com/authors/florian-martens) · Published Oct 11, 2026 Source: https://pipe0.com/reviews/blitz Scoring method: https://pipe0.com/reviews#methodology Disclosure: pipe0 sells data enrichment and competes with Blitz API in parts of this review. We say where Blitz API is better. > Blitz API sells unlimited B2B data for a flat monthly price. In our benchmark its emails were among the most consistent and came back in a third of a second, but it found an email for fewer than half the people. **Verdict: 3.8/5.** A fast, developer-first data API with unlimited lookups for a flat fee. The emails it returns are reliable, but it found one for 38 to 41% of people, and phones are US-only. | Criterion | Score | Why | | --- | --- | --- | | Ease of use | 4.0/5 | Clear docs, typed SDKs, and errors that name the fix. It is built for developers; other teams go through Clay, n8n, or Make. | | Data quality | 3.0/5 | Its emails agreed with other providers as often as anyone's, but it found one for 38% of profiles in our head-to-head test. Phones are US-only. | | Pricing value | 3.5/5 | Unlimited lookups for a flat fee are cheap at high volume, but email starts at $499 a month, whatever your volume. | | API and agent access | 4.5/5 | A synchronous API that answered in about 0.3 seconds, plus an MCP server with OAuth, built-in skills, and searchable docs. | | **Overall** (mean) | **3.8/5** | | **Best for:** - Teams enriching tens of thousands of LinkedIn profiles a month - Developers who want sub-second, synchronous lookups - Workflows that would rather skip a person than risk a bad email **Skip it if:** - You need an email for as many people on your list as possible - You need mobile numbers outside the United States - Your volume is low or uneven from month to month **Price:** from $399/mo for Unlimited Leads, without email or phone lookups. No free plan. ## Blitz API at a glance - **Database:** 550M+ LinkedIn-based contacts and 65M+ verified emails, according to Blitz ([source](https://docs.blitz-api.ai/guide/concepts/quality)) - **Phones:** 45M+ mobile numbers, United States only, according to Blitz ([source](https://docs.blitz-api.ai/guide/concepts/quality)) - **API:** Synchronous REST with a LinkedIn URL or email as input; typed Python and TypeScript SDKs ([source](https://docs.blitz-api.ai/sdks/overview)) - **MCP server:** api.blitz-api.ai/mcp, OAuth or API key; one tool per endpoint ([source](https://docs.blitz-api.ai/guide/integrations/MCP)) - **Integrations:** Clay, n8n, Make ([source](https://docs.blitz-api.ai/guide/integrations/clay)) ## Blitz API in our benchmark pipe0 ran the same records through every provider it tests (October 2026). | Test | Records | Coverage | Agreement | Median time | Run | | --- | --- | --- | --- | --- | --- | | LinkedIn URL to work email (LinkedIn profiles) | 120 | 37.5% | 73% | 0.3 s | 20261011T173839Z-27b0 | | LinkedIn URL to work email, all profiles (LinkedIn profiles) | 1,204 | 41.1% | – | 0.3 s | 20261011T174046Z-5a57 | | Email to LinkedIn URL (signup emails) | 100 | 10% | 94% | 0.3 s | 20261011T173957Z-de8f | ### How often Blitz API agrees with other providers LinkedIn URL to work email (run 20261011T173839Z-27b0). - Wiza: Blitz API and Wiza returned the same work email for 34 of 42 people (81%). - Surfe: Blitz API and Surfe returned the same work email for 31 of 41 people (76%). - Amplemarket (premium): Blitz API and Amplemarket returned the same work email for 26 of 35 people (74%). - On the same 120 profiles, pipe0's default work email waterfall found 84%, and Blitz found no email it missed. - From the same 100 emails, pipe0's reverse lookup waterfall found a LinkedIn profile for 29%, against Blitz's 10%. - Across all 1,204 profiles, Blitz's coverage ran from 54% in the United States to 30% in Spain. - Phone lookups weren't part of this test. - Each test ran on 100 to 1,204 records. - The LinkedIn profile set passed one vendor's resolvability filter, so absolute rates run higher than on a typical list. Comparisons between providers stay fair. - The signup set is real pipe0 signup emails with no vendor involved in choosing them, a harder and more realistic population than the profile set. - Agreement is the share of results that match what other providers returned for the same person. It is a proxy for accuracy, not ground truth. ## What is Blitz API? [#what-is-blitz-api] Blitz API is a B2B data API built around a LinkedIn-based dataset of more than 550 million contacts. It finds people at companies, enriches LinkedIn profiles, and returns work emails and, in the United States, mobile numbers. Its pitch is the price model. Instead of charging per lookup, Blitz sells three flat monthly plans with unlimited use, subject to a fair use policy. ## Precise, but it finds less [#precise-but-it-finds-less] Blitz says it never guesses an email from a name pattern and would rather return nothing than a risky address. Our benchmark matches that. We ran Blitz on the same 120 LinkedIn profiles as nine other providers. When Blitz and another provider both found an email, they agreed 73% of the time, tied with Hunter for the most consistent of the ten. But Blitz found an email for only 45 of the 120, or 38%. Across all 1,204 profiles in our dataset it found 41%, from 54% in the United States down to 30% in Spain. For comparison, pipe0's default work email waterfall found an email for 101 of the same 120 people, 84%, and every person Blitz found was among them. Starting from an email, Blitz found the LinkedIn profile for 10 of 100 people, against 29 for pipe0's reverse lookup waterfall. ## Fast and built for agents [#fast-and-built-for-agents] Blitz answered in a median of 0.3 seconds, synchronously. Several contact providers take seconds per lookup or make you poll for results, so this matters if an agent or a live form is waiting. The MCP server exposes one tool per API endpoint and signs in with OAuth, and the docs ship with an llms.txt index and built-in skills for agents. Errors name the field that was wrong and the closest valid value. ## What it costs [#what-it-costs] There are three plans: $399 a month for search and company data, $499 to add work emails, and $599 to add mobile numbers, which cover the United States only. A free trial includes 1,000 records, and phone lookups aren't part of it. Flat-rate pricing is cheap when you run tens of thousands of lookups a month. At lower volume, $499 buys fewer emails than paying per result would. Because Blitz found an email for fewer than half the people we tested, the real cost per email found is about two and a half times the cost per lookup. ## Blitz API and pipe0 [#blitz-api-and-pipe0] pipe0 competes with Blitz and doesn't use it in its waterfalls. We tested it on the same inputs as every other provider in our benchmark. If you already pay for Blitz, the two work together: run Blitz first and send only the people it misses through pipe0. In our test that kept coverage at 84% and cut pipe0 spend by about 40%. ## Who should buy Blitz API [#who-should-buy-blitz-api] Buy Blitz if you enrich tens of thousands of LinkedIn profiles a month, want answers in under a second, and would rather skip a person than send to a doubtful address. Look elsewhere if you need an email for as many people on your list as possible, mobile numbers outside the United States, or if your volume is low. ## Blitz API pros and cons ### Pros - **Consistent answers.** When Blitz and another provider both found an email, they agreed 73% of the time, tied for the highest of the 10 providers we tested. - **Fast.** Lookups came back in a median of 0.3 seconds, synchronously. Many contact providers take several seconds or make you poll. - **Flat-rate unlimited.** Paid plans have no per-lookup fees, so re-running a list or testing a new workflow costs nothing extra. - **Agent-ready.** An MCP server with one tool per endpoint and OAuth sign-in, plus an llms.txt index and Python and TypeScript SDKs. ### Cons - **Lower coverage.** From 120 LinkedIn profiles, Blitz found a work email for 38%. A waterfall of four providers found 84% of the same people. - **Phones are US-only.** Blitz says its 45 million mobile numbers cover only the United States, and phone lookups need the $599 plan. - **A high floor.** Email lookups need the $499 a month plan. At low volume that is more per email than paying per result. - **Developers only.** Blitz is an API. Without a developer, you work through integrations such as Clay, n8n, or Make. ## Blitz API pricing | Plan | Price | What you get | | --- | --- | --- | | Free trial | $0 | 1,000 records, charged per result found.
