Scrapin.io & EnrichLayer Credit Rollover Rules Explained for GTM Engineers

Why GTM engineering budgets get burned by $30 7-day trials, $500 upfront PAYG thresholds, monthly subscription resets, and 2–10x multi-credit endpoint multipliers—and how never-expiring per-item PAYG cuts real enrichment bills by 90%+.

  • →Scrapin.io gates sandbox testing behind a $30 paid 7-day trial (zero rollover after Day 7) and requires a $500 upfront minimum for 12-month PAYG packs ($9.99–$15.00 per 1,000 profiles).
  • →EnrichLayer monthly plans ($49–$299+/mo) forfeit unused subscription credits at cycle reset, while micro-PAYG starts near $0.10/credit ($100.00 per 1,000 base API calls) and charges 2–10+ credits per profile when live refresh or extra parameters are toggled.
