BlitzAPI vs FullEnrich (2026): Data, Pricing and API Compared

BlitzAPI sells work emails on one flat fee, which favors volume. FullEnrich is the better pick for phone numbers, because it asks 25+ sources for each contact. Neither publishes a 1M price for an account opened today.

Verdict

• Pick BlitzAPI if you start from LinkedIn URLs or search by title and company, want a flat monthly fee, and need work emails in volume. It also carries 100M+ job postings for hiring signals (BlitzAPI pricing, September 2026).
• Pick FullEnrich if you need mobile numbers and want to pay only for what it finds. Its MCP server returns records, and bulk CSV comes with every plan (FullEnrich pricing, September 2026).
• Pick neither if you want emails, phones, search and export on one price with no credits and no data-type tiers. LeadOcean is one option, covered below.

Side by side

Data and coverage

BlitzAPI is a database you query. FullEnrich is a service that asks other databases. That split explains most of the table.

BlitzAPI lists 550M+ profiles and 65M+ companies, all tied to LinkedIn. Verified work emails number 65M+, about 12% of profiles, and an address it cannot prove comes back Not Found (BlitzAPI pricing, September 2026). It also lists 100M+ job postings, which FullEnrich does not.

FullEnrich lists 800M people and 50M companies for search. Search results carry no emails or phones, so you enrich the people you pick. The 1.6B figure on its homepage is a customer quote about coverage, not a database size (FullEnrich MCP page, September 2026).

Phones are where they split. BlitzAPI's 45M+ numbers are US only, and they sit on the $599 Full plan (BlitzAPI docs, September 2026). FullEnrich waterfalls 25+ sources for mobiles at 10 credits each, and it publishes no phone count or country split. Run a sample of your own regions through both before you commit.

Verification differs too. BlitzAPI re-tests its emails at least every 30 days and never guesses from a name pattern. FullEnrich says about 30% of raw data is removed by verification before it reaches you, and it states about an 80% find rate on work emails (FullEnrich pricing, September 2026). Both are vendor claims. We did not test either.

API and developer experience

Both tools are REST APIs on every plan, but they differ in shape. BlitzAPI answers an email lookup in the same call. FullEnrich runs an asynchronous bulk job and tells you the result on a webhook. Placeholders below stand in for real people.

BlitzAPI, find a work email from a LinkedIn URL.

curl --request POST \
  --url "https://api.blitz-api.ai/v2/enrichment/email" \
  --header "x-api-key: $BLITZAPI_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{"person_linkedin_url": "https://www.linkedin.com/in/jane-doe"}'

The response carries found, the email and an all_emails list (BlitzAPI docs, September 2026). One result is one email, and a call that finds nothing counts nothing. The input is a LinkedIn URL, so a list of names and domains needs a search step first.

FullEnrich, start a bulk enrichment for one contact. It takes up to 100.

curl --request POST \
  --url "https://app.fullenrich.com/api/v2/contact/enrich/bulk" \
  --header "Authorization: Bearer $FULLENRICH_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "name": "Jane Doe",
    "webhook_url": "https://example.com/webhook",
    "data": [{
      "linkedin_url": "https://www.linkedin.com/in/jane-doe",
      "enrich_fields": ["contact.work_emails", "contact.phones"]
    }]
  }'

You get the result on your webhook, or you poll GET /bulk/{enrichment_id}, which the docs do not recommend (FullEnrich docs, September 2026). Input can be a LinkedIn URL, or a name with a company domain. A LinkedIn URL also returns a full profile.

Rate limits shape the work. At 1M single email lookups, BlitzAPI at 50 requests per second needs 1,000,000 / 50 = 20,000 seconds, about 5.6 hours. At the standard 5 it needs 200,000 seconds, about 2.3 days. FullEnrich allows 100 contacts per call and 60 calls a minute, so 6,000 contacts a minute at the ceiling, about 167 minutes for 1M. Over the limit, FullEnrich returns HTTP 429 until the next calendar minute (FullEnrich docs, September 2026).

On MCP, the two are not alike. BlitzAPI's server gives an AI tool the API documentation, so an agent cannot search people or enrich a lead through it. FullEnrich's server uses OAuth, lists search, enrich and export, and shows the first 10 search results plus the total count at no cost (FullEnrich help, September 2026).

Pricing

BlitzAPI sells three flat plans by data type: Core $399 a month without emails or phones, Plus $499 with verified work emails, Full $599 with US phones added. FullEnrich sells credits: 1 for a work email, 3 for a personal email, 10 for a mobile, and nothing for a miss (BlitzAPI pricing, September 2026; FullEnrich docs, September 2026).

The worked example is work-email lookups only, one result or credit each, at monthly list price first and billed-yearly after.

At 10,000 emails a month the two cost the same on monthly billing, $499. FullEnrich billed yearly is $454, so it is $45 cheaper there (FullEnrich pricing, September 2026). On launch-offer accounts BlitzAPI pulls ahead as volume grows, because its fee does not move with volume.

At 1M the BlitzAPI figure is the list price for accounts opened by September 30, 2026. The 15,000,000 results a month line comes from Terms section 9.1 (BlitzAPI Terms, September 2026). The offer closed to new accounts after that date. BlitzAPI has not published prices or monthly volume for later accounts, and the only published standard rate is 5 requests per second (BlitzAPI pricing, BlitzAPI Terms, section 9.1). Only emails it finds count as results, so 1M lookups return at most 1M results.

FullEnrich publishes no 1M price. The top monthly tier is 100,000 credits for $3,500 ($0.035 a credit), and above it the page says contact sales. The yearly toggle stops at 1,200,000 credits a year for $37,800, which is a year of credits, not one month (FullEnrich pricing, September 2026). A million lookups in one month needs a quote.

Both bills move with what you ask for. On BlitzAPI the data type sets the plan, so adding phones moves you from $499 to $599 at any volume. On FullEnrich the data type sets the credits per record, so adding phones multiplies the bill with every row.

Phones change the sums. Take 10,000 US mobiles. FullEnrich needs 10 x 10,000 = 100,000 credits, which fills the top public tier at $3,500 a month, if every one is found. BlitzAPI Full is $599 a month for US numbers, with no per-result charge on paid plans. Neither figure is a promise of hit rate, so sample first.

Where BlitzAPI wins

• A flat fee with no credit meter. On accounts opened by September 30, 2026, $499 covers work emails at 10,000 or 1M, at 50 requests per second.
• Job postings and hiring signals, with 100M+ postings and endpoints to search them.
• A synchronous email lookup that answers in the same call.

Where FullEnrich wins

• Phone coverage. A waterfall over 25+ sources finds numbers one database misses, and BlitzAPI's phones stop at the US border.
• Pay for hits only. A miss or a landline costs nothing, and unused credits roll over for 3 months on monthly plans.
• An MCP server that returns records, plus bulk CSV and unlimited users on every plan.
• A larger search index on paper, at 800M people against 550M+ profiles.
