RepDB
A simple to integrate Geolocation API that provides information about your users, either directly from a browser or device, or from any of your servers.
Provides data such as City, Region, Postal code, Country, Continent, Coordinates, Timezone, Currency, Organization, ISP, AS, if they are using a mobile network, or an anonymous proxy/VPN.
Works with IPv4, IPv6 or hostnames. Supports batch requests with up to 100 queries per HTTP request.
The free version requires no sign up or keys, and it's limited to 45 HTTP requests per minute from an IP address. Non-commercial use only.
The pro service includes more features such as SLA for 99.9% of monthly uptime, a dashboard with usage statistics, up to 10 API keys (customizable with restrictions), and more.
RepDB is a one-time-purchase exercise dataset with animations for developers building fitness and workout apps — not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.
A free tier includes 600+ exercises with flat-style 512×512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings — exclusive to that tier.
Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.
IP-API.com RepDBRepDB's answer:
RepDB is sold as a one-time download, not a metered API — you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.
RepDB's answer:
RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.
RepDB's answer:
Most alternatives are subscription APIs — you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.
RepDB's answer:
Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.

Free public geo APIs do not love datacenter traffic. My first instinct was to use ip-api.com — it’s the go-to for “what country is this IP” lookups and has a generous free tier. Hooked it up, ran the direct profile, got a clean response. Then I ran it through the Bright Data proxies I had (these) and got a HTTP 402. Turns out ip-api.com’s free tier detects any datacenter egress and refuses to serve it. The proxy... - Source: dev.to / 3 months ago
The original version used http://ip-api.com — plain HTTP. On a cloud server, that traffic is unencrypted and could be intercepted and spoofed. I switched to https://ipinfo.io which supports HTTPS on the free tier. - Source: dev.to / 6 months ago
In this example, I'll process messages based on their originating IP address. Multiple threads will enrich them with location data fetched from the public API at https://ip-api.com/. - Source: dev.to / 8 months ago

The Language may be different: You can check up the [Set language based on IP], and make the system automatically set up the browser language according to the IP that you set up. Mismatch of DNS or system time: We recommend you to replace the proxy IP and start the operation. Or you can enter the site https://ip-api.com for verification. Source: over 2 years ago
