Free ipify-compatible IP & Geolocation Service Launched
A developer team launched whatsmy.fyi, a free, ipify-compatible service that provides a keyless IP endpoint and an authenticated API (10,000 requests/day free tier) returning geolocation, ASN, ISP, timezone and coordinates. The project aims to be drop-in compatible with api.ipify.org, offers CORS-enabled keyless calls, a TypeScript SDK with keyless mode, and leverages Cloudflare Workers (request.cf) to obtain geo/ASN/timezone data at the edge without an external GeoIP database. The author highlights lessons about low friction adoption, edge economics changing paid/ free feature splits, and the importance of long-term maintenance and prompt community responses.
A small open alternative to a widely used IP API lowers friction for developers and changes the cost dynamics of serving geo/ASN data by leveraging edge platform metadata—relevant to identity/geo data access but not industry‑shifting.

Key Takeaways & Evidence Grounding
- whatsmy.fyi launched a keyless endpoint compatible with api.ipify.org that returns plain-text and JSON IP responses.
- The authenticated whatsmy.fyi API offers a free API key tier with 10,000 requests/day and returns city, country, coordinates, timezone, ASN, and ISP.
- The project uses Cloudflare Workers (request.cf) to obtain geolocation, ASN and timezone at the edge, avoiding external GeoIP database lookups.
- The ipify open-source repository showed no code changes since January 2018; ipify's hosted service is commercially operated by WhoisXML API.
- A TypeScript SDK (@whatsmyfyi/sdk) is available with a keyless mode and the project publishes API docs and an OpenAPI spec.

Single IP Lookup for Geo-Personalization (IPv4/IPv6)
A developer post by Daniel Igel (published 2026-06-13 on DEV Community) describes a lightweight IP geolocation API hosted via RapidAPI that returns country, region, city, latitude/longitude and timezone in a single request. The API supports both IPv4 and IPv6 and provides convenience endpoints including /api/v1/geo?ip=..., /api/v1/geo/me to resolve the caller IP, and /api/v1/geo/batch for bulk enrichment of logs or signups. The author built the service to avoid bundling large GeoIP databases like MaxMind for small projects. A free tier is available on RapidAPI. The post targets developers needing simple geo-personalization for currency, language, fraud detection or analytics.
IP Geolocation for Fraud Detection: Developer Guide
A developer tutorial by ApogeoAPI (published May 4, 2026) explaining how to use IP geolocation as a fraud-detection signal. The guide describes four core IP-based signals—impossible travel, country mismatch, high-risk regions, and anonymous IP/VPN detection—and provides Node.js/TypeScript code examples (haversine distance, country checks, high-risk country lists) and a simple risk-scoring function that aggregates signals into a 0–100 score. The article notes VPN/proxy detection requires specialized services (e.g., IPQualityScore, Fraudlabs Pro), warns against blocking users solely on IP, and highlights privacy and regulatory caveats (GDPR/CCPA). It recommends combining IP signals with other signals (device fingerprinting, behavioral analysis, payment signals) and providing user remediation paths rather than silent blocks.
IPinfo launches self-service residential proxy detection API
IPinfo announced that its residential proxy detection dataset is now available via a self-service API as part of the IPinfo Max product, removing the need for enterprise procurement. The directly observed dataset has surpassed 107 million residential proxy IPs (≈2.3x year-over-year growth) and covers 126 residential proxy providers across roughly 35,000 autonomous systems. IPinfo builds the dataset from direct observation—continuously validating active endpoints—and reports that the average proxy IP is visible for 4.56 days while 60% are seen only once in a 90-day window. The API returns contextual signals such as last_seen, percent_days_seen, and provider_name. The offering targets security, fraud, and adtech teams seeking to improve traffic quality, measurement, and abuse detection and is available via transparent monthly or annual pricing.
