A free, privacy-first IP address lookup API powered by our global edge network. Part of the FindUtils ecosystem of 300+ developer tools.
ipfast.dev is a public API that returns your IP address, geolocation, connection security details, and parsed user agent data. It runs as a edge service across 300+ edge locations worldwide, which means your request is processed by the server geographically closest to you.
Unlike most IP lookup services, we make zero external API calls. All geolocation data comes directly from the edge network, which already knows your IP address, country, city, coordinates, and ASN as part of its normal request routing. We simply read that data and return it to you in your preferred format.
The result is an IP lookup service with near-zero latency overhead, because there are no external lookups, no database queries, and no third-party API calls to wait for.
Developers constantly need to look up IP addresses -- in shell scripts, CI pipelines, monitoring tools, and application code. Most IP lookup APIs require signup, API keys, and have restrictive rate limits or expensive pricing tiers. Even free tiers typically require email verification and have monthly quotas.
For a simple "what's my IP?" check in a deployment script, that's too much friction.
One URL. Free API key. Just register in seconds at ipfast.dev/login (magic link, no password), then curl -H "X-API-Key: sk_live_xxx" ipfast.dev/text and you get your IP back. Need geolocation? Use /json. Need just the country? Use /country. Need all the data in one call? Use /all.
Free plan: 120 requests per minute, no monthly quotas, no premium tiers blocking essential features. Every endpoint is available to everyone.
Check your server's public IP, verify egress IPs in cloud environments, detect the geographic region of your deployment, or validate that your VPN/proxy is routing traffic correctly. Works with curl, wget, httpie, or any HTTP client.
Detect the visitor's timezone for date formatting, get their country for localization, or fetch their full geolocation for map-based features. Full CORS support means you can call the API directly from browser JavaScript.
Embed IP checks in deployment scripts, health checks, and monitoring dashboards. Use the plain text endpoints (/text, /country) that return a single value with no JSON parsing required -- perfect for shell scripting.
Inspect connection security properties: TLS version, cipher suite, HTTP protocol version. Verify that your client supports modern encryption standards. Check if user agents are being detected as bots.
Request logs use a SHA-256 hash of your IP address for rate limiting and abuse prevention. The original IP address is never written to disk, never stored in a database, and never sent to any third party.
There are no cookies, no tracking pixels, no analytics scripts, no user accounts, and no fingerprinting. The service returns your data and moves on. Your request exists only for the milliseconds it takes to generate a response.
Built on serverless edge infrastructure. Your request is handled at the nearest data center with sub-5ms response time. No origin server, no database, no external dependencies.
