IP Geolocation
Requiems API vs IPstack
IPstack (an APILayer product) delivers real-time IP geolocation covering 100+ data fields: country, region, city, timezone, currency, ISP, and threat intelligence. IPv4 and IPv6 supported.
One vendor for IP + email + phone
IPstack is geolocation-only. Requiems API provides the same location data plus email verification, phone validation, and more.
No legacy APILayer baggage
IPstack runs on APILayer infrastructure with slow release cadence. Requiems API ships improvements continuously.
Richer free tier
IPstack free = 100 req/mo. Requiems API free = 500 req/mo across every endpoint type.

Philosophy
IPstack is a mature geolocation product from APILayer. If you only need IP-to-location data and prefer a well-known brand, it works. Requiems API is the better fit when your app already uses β or will eventually need β email, phone, or other validation signals: one key, one bill, one docs site.
Migrating from IPstack
-
1
Replace `api.ipstack.com/{ip}` with `requiems.xyz/v1/ip/lookup?ip={ip}`
-
2
Swap `access_key` query param for `requiems-api-key: <key>` header
-
3
Most response fields are identical; map `location.geoname_id` to `geoname_id` at root level
