Geolocate any IP (country, city, ISP, ASN) with no key

ip-api.com resolves an IP address to country, region, city, coordinates, timezone, ISP, organization, and ASN. The keyless free tier allows up to 45 requests per minute per IP and works for any IP you pass in. Useful for enriching logs, requests, or signups with rough geo context.
