The IP API

About The IP API

The IP API is a developer-focused IP geolocation and address lookup service providing country, city, ASN, timezone, and currency data through a single API call. It supports both IPv4 and IPv6 addresses, returns JSON responses, and offers client examples in curl, Node, Python, and Go. The service operates across multiple regions with a stated 99.95% uptime SLA and includes a batch/bulk lookup endpoint for ETL and data warehouse use cases.

The product is positioned for use cases including e-commerce (localized pricing, currency, and tax detection), cybersecurity (suspicious login and impossible-travel detection via ASN and proxy flags), travel and hospitality (localized booking content), ad tech (geo-targeted campaigns and bot/VPN filtering), streaming (geo-restriction and licensing enforcement), and analytics (enriched traffic data with ASN and ISP attribution).

A free tier offers 1,000 requests per day without requiring a credit card, with paid usage beyond that tier. The company also offers a separate product, MailFixture, for disposable inboxes used in automated email testing.
