What it really is

People Data Labs — B2B person data enrichment API for professional profiles and contact intelligence.

Our take

People Data Labs' Person API delivers one of the market's most comprehensive professional enrichment datasets — covering work history, education, emails, phone numbers, demographics, and inferred attributes across 1.5B+ profiles. The DB lists $79/mo as entry price, but the current Pro plan starts at $98/mo (350 credits). The DB's 'who_its_for' field incorrectly references Amazon product/ecommerce feeds — PDL is entirely a B2B people-data layer for recruiting, sales, and HR applications.

Why we rate it

PDL's dataset breadth and API reliability are hard to match at this price point. The free tier is genuinely useful for prototyping, and the credit model makes costs predictable for mid-volume use cases.

The catch

Free tier withholds contact data (emails/phones) entirely; premium field bundles stack costs quickly beyond the base credit price; enterprise volumes require custom contracts with minimum commitments.

Best for
Sales ops teams enriching CRM leads with professional context
Recruiting platforms sourcing and verifying candidate profiles
HR tech and identity-resolution products needing structured person data
Not good for
Ecommerce or consumer-data use cases (B2C profiles not the focus)
Teams needing real-time contact verification rather than enrichment
Startups on a tight budget who need email/phone data — costs escalate fast with add-ons
Friction report
Time to value
Fast: API key provisioned on signup; first enrichment call possible within minutes using REST or the Python/Node SDKs.
Scale breakpoint
Per-credit pricing compounds sharply when contact data add-ons are included; enterprise contracts required above ~100k annual lookups.
Walled garden
Moderate: data is returned via API with no proprietary UI lock-in, but bulk exports and data licensing require enterprise agreements.
