IP Geolocation API - 2026 Pricing, Features, Reviews & Alternatives

IP Geolocation API provides comprehensive location and network intelligence through a single HTTP request. The API returns city-level geolocation, autonomous system details, timezone, currency and security information for both IPv four and IPv six addresses. No API key is required for basic lookups and subscription plans enable security detection and higher volume allowances. The service suits developers and security teams seeking to integrate precise IP intelligence into applications for fraud prevention, content localization, access control and traffic analysis.

The core geolocation response includes country, region, city, postal code, latitude and longitude data alongside an accuracy radius expressed in kilometres. Connection details incorporate autonomous system number, organisation name, internet service provider and domain data sourced from a regularly refreshed database of autonomous systems and IP ranges. Timezone information comprises IANA identifiers, UTC offset and daylight saving time status with transition dates. Currency data consists of ISO code, symbol, name and exchange rate. Enabling the optional security parameter adds threat intelligence such as proxy detection, VPN identification, TOR exit node flags, hosting provider classification, relay detection, composite threat scores and confidence scoring.

The API offers multiple endpoints under a single base URL for functions such as ASN lookup, timezone conversion, astronomy calculations, user agent parsing, abuse contact retrieval, reverse DNS resolution and threat feed access. Clients may filter responses using dot-path notation to include or exclude specific data fields. Output formats include JSON, XML and CSV. Bulk operations allow synchronous inline lookups for up to one hundred addresses or asynchronous jobs for larger datasets with webhook notifications upon completion. The service publishes an OpenAPI specification for automated client generation and requires no additional SDK for integration.

Rate limiting enforces request quotas with standard error responses and retry headers when limits are reached and counters reset daily at midnight Coordinated Universal Time. The platform runs on a cloud infrastructure with edge distribution, offering a public status page with historical uptime and component health metrics. Authentication for subscription plans uses API keys passed via headers or query parameters. Data processing agreements cover retention policies, sub-processor disclosures and compliance with privacy regulations for European traffic.
