The GitHub lists are graveyards of dead links. This directory is different: our verified core was tested with real requests — receipts published — and the wider catalog is link-checked and honestly labeled. Run the verified ones yourself, right in your browser.
26 shelves, zero dead ends. Verified APIs carry receipts; listed ones carry honest labels.
Forecasts, geocoding, maps, countries and IP location.
Currency rates, crypto prices, stocks and world economic data.
LLMs, image models and AI utilities with real free tiers.
Photos, placeholders, avatars, QR codes and cat pictures.
Jokes, facts, quotes and gloriously pointless data.
Fake backends, research data and giant open datasets.
GitHub, package registries, testing and security utilities.
Dictionaries, books, poetry and wordplay engines.
Pokémon, anime, trivia, cards and entire fictional universes.
NASA, rockets, earthquakes and research archives.
Movies, shows, artists, albums and lyrics.
Recipes, cocktails, nutrition and breweries.
Teams, leagues, F1 history and live football data.
Pet data, animal facts, shelter and breed APIs.
Museums, design assets, color and creative-data APIs.
Company data, tracking, analytics and startup utilities.
Holidays, events, calendars and date utilities.
Email validation, messaging and phone-data APIs.
Official government datasets and public records.
Health data, nutrition, disease and medical reference APIs.
Job listings, careers data and hiring APIs.
Headlines, articles and media-monitoring APIs.
Anti-malware, threat intel and security-check APIs.
Products, prices, stores and commerce APIs.
Social networks, profiles and community APIs.
Transit, flights, vehicles and logistics APIs.
Hit "Try it live" on any keyless API and see the real JSON response — in your browser, in seconds. No signup, no Postman, no faith required.
Verified listings show their last live check and the actual response we captured; listed-tier entries stay labeled until they earn verification. If an API dies, its page says so — in red, in public.
Head-to-head pages — Open-Meteo vs OpenWeatherMap and more — with a verdict, not a shrug.

One email, every Friday: the week's new APIs, who went down, who recovered, and one build idea worth your weekend. Read by developers who would rather build than browse lists.

An API with a tier that costs nothing to use. Two flavors live here: fully keyless APIs (call them right now, no account — like Open-Meteo or Cat Facts) and free-key APIs (a free account unlocks a key and a monthly quota — like NASA or TMDB). Every listing on this site states which one it is, with the real limits.
Use the "No key needed" filter in the catalog, or start from our ranked list of the best no-key APIs. The most-loved keyless ones: Open-Meteo (weather), REST Countries, PokeAPI, JSONPlaceholder (fake data), Free Dictionary and Dog CEO. They answer the first time you call them — that is the whole point.
Two tiers. Verified APIs are called with a real HTTP request from our checker: we publish the status, the response time and the actual response we captured, and we re-run the check weekly. Listed APIs come from the open public-apis dataset (MIT license) and are link-checked — their official site must answer — until they graduate to a full endpoint test. The tiers are labeled on every page; we never blur them.
CORS ✓ means your browser is allowed to call the API directly from front-end JavaScript. Without it, the browser blocks the call and you need a small backend or proxy in between. If you are building a pure front-end project, filter for CORS ✓ and save yourself an afternoon.
Sometimes. Each provider sets its own terms: some free tiers are non-commercial only (Open-Meteo is the famous example), some allow commercial use up to the quota, some require attribution. Every listing here links the official docs — check the terms there before you ship something paying. When in doubt, email the provider; the free-API world is friendly.
Because it failed our last weekly check from our network — the honest answer, published in red with the date. It may be down for everyone, down only for some regions, or rate-limiting shared IPs (it happens to NASA’s DEMO_KEY constantly). We would rather show you a scar than a fake smile.
The verification run repeats weekly: statuses, response times and captured responses refresh, dead links drop off, and listed APIs graduate to verified as endpoint tests complete. New submissions are reviewed between runs.
Tip: edit the URL above — change a city, a name, a symbol — and run it again. That is literally how APIs are learned.
