Multi-Purpose
Requiems API vs AbstractAPI
AbstractAPI offers 20+ focused APIs — email verification, IP geolocation, phone validation, company enrichment, holidays, and more — each under a separate key and separate subscription. Strong DX; fragmented billing.
One key, not twenty
AbstractAPI gives you one key per API product. Requiems API gives you one key for all 100+ endpoints.
One invoice
AbstractAPI has a separate plan per product — you end up with multiple subscriptions. Requiems API is one bill.
Consistent schema
AbstractAPI response shapes vary per product. Requiems API uses a consistent envelope, error format, and auth method across everything.

Philosophy
AbstractAPI built excellent individual API products — their email and IP products in particular are well-regarded. But each one is a separate account, key, and plan. Requiems API started from the opposite question: what if every API you'll ever need shared one account? We traded the per-product polish of a specialist for the operational simplicity of a unified platform.
Migrating from AbstractAPI
-
1
Replace `emailvalidation.abstractapi.com`, `ipgeolocation.abstractapi.com`, etc. with `requiems.xyz/v1/{category}/{endpoint}`
-
2
Swap `api_key` query param for `requiems-api-key: <key>` header — same key works for every endpoint
-

Response field names are similar; consult per-endpoint migration notes in our docs
