Why it comes up: Self-serve person data API with a free plan and public pricing.
Stands out: A free API sandbox, then self-serve Pro with contact data, premium fields and CSV enrichment on monthly or annual terms.
Watch out: Free hides email, phone and address. Annual saves 20% but is paid up front. Bulk data licenses are Enterprise and custom priced.
Best for
- Developers enriching person records via API
- Products that may later license a bulk feed
- RevOps running CSV enrichment

Why it comes up: Enterprise B2B data platform if prospecting is the main job.
Stands out: The buying-committee graph and intent data, not just email lookup.
Watch out: Recruiter-only desks should price Wiza, ContactOut or Tomba first. This is an enterprise contract.
Best for
- Talent teams where sales already pays for ZoomInfo
- Desks that need reports-to lines and org charts
- Account-based recruiting with intent data

Why it comes up: Enrichment API for emails and phones on a smaller budget.
Stands out: You pay only for a verified match, catch-all emails are not billed, and unused credits roll over for 12 months.
Watch out: Regular includes 100 phones and 3,000 emails a month on one seat. Extra seats are $5/user/mo, and the interface is lighter than a full sales tool.
Best for
- RevOps teams enriching a CRM by API
- Clay, Make and Zapier users
- Teams prospecting in Europe

$49/mo Free tier Free trial MCP API
Why it comes up: B2B database plus outreach app for sales teams.
Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.
Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.
Best for
- Outbound recruiting and sales on one database
- Teams that want free-tier access to start
- Desks that need sequences next to the data
