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

FullEnrich is the pick when code or an agent fills in emails and mobiles at volume. Wiza is the pick when a rep prospects from LinkedIn, one list at a time. At 1M records, neither publishes a price.

Verdict

• Pick FullEnrich if you hold names, domains or LinkedIn URLs and need work emails and mobiles filled in by API. It has no per-seat fee, and API and MCP are on every plan, including the free trial (FullEnrich pricing, September 2026).
• Pick Wiza if reps build lists in LinkedIn Sales Navigator and want contact data checked at the moment of the request. Plans are priced per user (Wiza pricing, September 2026).
• Pick neither if you pull whole audiences by API, filter by title, industry and funding before you spend, and want a fixed bill. LeadOcean is one option, covered below.

Side by side

Data and coverage

The two numbers in the table are not the same kind of count. FullEnrich lists 800M people and 50M companies in search, and search results carry no emails or phones (FullEnrich pricing, September 2026). Wiza says 850M+ contacts and publishes no company count (Wiza, September 2026). On paper Wiza has the larger people file. Neither number is tested.

FullEnrich's 1.6B figure is a customer quote about coverage, not a database size (FullEnrich MCP page, September 2026). Do not compare it to Wiza's 850M.

The data is sourced differently. FullEnrich asks 25+ sources in sequence, so a miss at one source can be a hit at the next. Wiza says it verifies contact data the moment you request it, against live sources (Wiza, September 2026).

Email quality is reported in different ways. FullEnrich runs a triple verification and returns four statuses: deliverable (a stated 2% bounce rate), high probability (9%), catch-all and invalid (FullEnrich docs, September 2026). Wiza charges only for emails it marks valid (Wiza docs, September 2026). Both are vendor claims.

Neither vendor publishes how many of its records carry a phone number. That makes a phone-coverage comparison a test you run, not a number you read. Phones are where FullEnrich leans hardest. A mobile costs 10 credits, a landline returns free, and the waterfall is built for that gap. Wiza returns phones at 5 API credits each. Run 200 rows of your own list through both before you commit.

API and developer experience

Both tools use a bearer token. Both tools find a contact from a LinkedIn URL. FullEnrich also takes a name plus a domain, and it is built for batches of 100. Placeholders below stand in for real people. FullEnrich's docs say a LinkedIn URL lifts email hit rates by 5 to 20% and mobile hit rates by 10 to 60% (FullEnrich docs, September 2026). We did not test that claim.

FullEnrich, start a bulk enrichment for one contact.

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": [{
      "first_name": "Jane",
      "last_name": "Doe",
      "domain": "acme.com",
      "enrich_fields": ["contact.work_emails", "contact.phones"]
    }]
  }'

The job is asynchronous. You get the result on a webhook, or you poll with the enrichment id (FullEnrich docs, September 2026). Polling also counts against the 60 calls a minute.

Wiza, start an individual reveal for one LinkedIn profile.

curl -X POST https://wiza.co/api/individual_reveals \
  -H "Authorization: Bearer $WIZA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "individual_reveal": {
      "profile_url": "https://www.linkedin.com/in/jane-doe/"
    },
    "enrichment_level": "email"
  }'

This is the docs example with the level set to email (Wiza docs, September 2026). You read the result with a GET on the reveal id, and the response shows the credits deducted. Wiza's bulk route is the same endpoint called in parallel, up to your concurrency limit (Wiza docs, September 2026).

The limits differ in shape. FullEnrich allows 60 calls a minute with 100 contacts per call, so up to 6,000 contacts a minute (FullEnrich docs, September 2026). Wiza's help center says 15 requests a second on Individual Reveal. Its docs describe the same limit as parallel requests in flight: 5 on Starter API, 15+ on Enterprise API, with a queue of 200 times that. Over the limit, Wiza returns HTTP 429 (Wiza help, July 2026). Wiza prospect search returns at most 30 results per call (Wiza docs, September 2026).

On MCP, both use OAuth. FullEnrich's server gives a free preview of the first 10 search results and the total, and an export costs 0.25 credits per contact (FullEnrich help, September 2026). Wiza's has five tools: enrich contact, enrich company, credits, company search and prospect search. It needs API access and credits (Wiza MCP guide, September 2026).

Pricing

FullEnrich charges for what it finds, per credit, with unlimited users. Wiza charges per user, and sells API credits separately. FullEnrich credits roll over for 3 months on monthly plans and 12 on annual ones (FullEnrich pricing, September 2026). Wiza API credits are valid for 12 months. The worked example below is work emails first, then mobiles, at list price.

FullEnrich figures come from its monthly and yearly tables (FullEnrich pricing, September 2026). Wiza figures use the monthly per-user plans and the per-extra rates (Wiza pricing, September 2026). The Wiza rows are the app route, one seat, and assume every contact is a hit.

The seat is the catch. Wiza's annual Email plan is $83 a month per user with unlimited email reveals, but exports stop at 2,500 a month, and teams of 3 or more get custom pricing. API pricing is "Book a call" (Wiza API, September 2026). Credits are bought through a slider or an enterprise deal, and they last 12 months (Wiza docs, September 2026). Wiza publishes no dollar price per API credit, so an API cost at 10,000 has no list number.

At 10,000 work emails, FullEnrich is cheaper on a single seat: $499 against $1,524 on Wiza's monthly route. At 10,000 mobiles the two land within $24 of each other. Hit rates decide the real bill, and neither vendor publishes one you can plan on, apart from FullEnrich's own 80% claim.

At 1M, neither tool gives you a number. FullEnrich's top monthly tier is 100,000 credits for $3,500, which is 10% of the volume, and above that the page says contact sales. The yearly toggle stops at 1,200,000 credits a year for $37,800 (FullEnrich pricing, September 2026). FullEnrich does not say whether yearly credits arrive upfront or month by month, so that tier is not a confirmed path to 1M lookups in one month. Wiza's Team plan and API are quoted on a call. A million records a month needs a quote from either vendor.

Where FullEnrich wins

• Mobile coverage. A waterfall over 25+ sources finds numbers that one source misses.
• An API built for batches: 100 contacts per request, results on a webhook.
• Unlimited users on every plan, with API, MCP and bulk CSV from the free trial up.
• Search by name plus domain, not only by LinkedIn URL.
• A price list you can read at every tier up to 100,000 credits a month.

Where Wiza wins

• A LinkedIn workflow. It builds lists from Sales Navigator, Recruiter or a CSV, and a rep works inside it (Wiza help, July 2026).
• Live verification at the moment of the request, which suits a short, high-value list.
• A larger people count on paper: 850M+ against 800M.
• Cheaper for one person. Starter is $49 a month, and the annual Email plan is $83 a month with unlimited email reveals (Wiza pricing, September 2026).
• CRM integrations on every paid plan, plus AI Research on annual plans.

If you need volume through an API

LeadOcean is the data layer only: 693M people and 63M companies over REST and MCP. Pro is $499 a month flat with no credits and no per-record price, and Free gives you 1,000 records, one-off, with no card. The limit is 100 requests per second per key, and POST /v1/exports returns up to 50,000 rows per request. The MCP server has 12 tools. LeadOcean has no waterfall, LinkedIn list builder or extension, so it replaces neither tool for hunting mobiles or prospecting by hand. See pricing.
