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 β€” 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 β€” 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. 1

    Replace `emailvalidation.abstractapi.com`, `ipgeolocation.abstractapi.com`, etc. with `requiems.xyz/v1/{category}/{endpoint}`

  2. 2

    Swap `api_key` query param for `requiems-api-key: <key>` header β€” same key works for every endpoint

  3. 3

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