Is Abstract API worth the price?
Fair value
This pricing is generous for low-volume users but confusingly structured.
The Free tier offers 100 requests at no cost, which is fair for testing. However, the Starter, Standard, and Professional tiers all cost between $17 and $39 per month for the same 5,000 requests, with overlapping features that make comparison difficult.
Best for small teams or developers needing basic email verification at low volume.
