How to choose a data api / marketplace tool

When evaluating a B2B data API, consider: data freshness model (static database vs live lookups), pricing structure (per-record vs subscription), GDPR posture (where is data stored and processed?), and response latency. PDL and similar providers offer raw data at high volume with developer-friendly APIs. Enrich-CRM's API adds a structured output layer — clean, CRM-ready fields with standardized values — reducing the engineering work needed to integrate enrichment into your stack.

Frequently asked questions

What is the best B2B data API?
People Data Labs (PDL) is the most developer-friendly B2B data API for raw, high-volume enrichment. Enrich-CRM's API is optimized for revenue teams: structured CRM-ready output, EU data residency (AWS Paris), no engineering team required. Both are credits-based, but Enrich-CRM returns clean, standardized fields rather than raw data.
How much does a B2B data API cost?
B2B data API pricing varies widely: PDL charges from ~$0.002/record at scale; Clearbit's API was $299+/month before being folded into HubSpot Breeze; Enrich-CRM's API is included from €29/month (Growth plan) with 1,000 credits/month.
