A Collection of Free Public APIs That Is Tested Daily

What I really want is isoddapi.xyz.

Just like the npm package, all it should do is call isevenapi.xyz and invert the result.

But what do I do if I need to know if a number is odd?

I love their pricing options include larger ranges of numbers, and enterprise class also includes negative numbers. ha ha.

Best part is that 'sign up' links to https://archive.org/donate/

I Seven API vs is Even API. Can't say I saw it the right way at first.

I feel like one of the categories they are missing is 'APIs that can be done in one line of JavaScript"

I'm not saying these shouldn't exist, I think they're pretty funny, but everything in its place.

This made my day..

It was the first one I searched for. What a silly tool: Parity as a Service.

The possibility of an internet resource disappearing exists regardless of the resource type. Running an API Forwarder that could act as a common target for all your APIs might work. Give it the request, and it passes it on, records success, optionally sends a notification if an endpoint that previously succeeded is now failing.

Add a fancy feature of redirection with format changing to handle replacing dead APIs with new ones transparently.

If anybody makes one of these, they should totally make it a free public API. I'd use it, and I'm not certain if that would just be ironically.

Polling is a fool's errand, in my experience, since I'd guess a ton of the "how about now?" responses are "nope"

IMHO sitemap.xml and/or ActivityPub are sleeper approaches to helping the sites with the adversarial relationship they have with scrapers. In my experience, there are two schools of thought: play the very expensive game of cat and mouse (expensive for BOTH sides) of trying to verify the human-ness of visitors, or make it so the inevitable bots don't eat up very expensive and valuable resources that can be spent serving actual humans

Imagine how much less nonsense would have to go on if Amazon had ActivityPub that CamelCamelCamel could subscribe to, or similar for Craigslist

I'm not saying "all information wants to be free," so if Amazon wants to focus its energies on hoarding the review content, since that's arguably its moat, fantastic - let the bot and anti-bot people war over that content, instead of arguably factual data found on the product listing pages

Not so much for polling data, but some governments do allow access to coarse election data.

Australia's was enough that the unfortunately complicated math of their election system was repeatable and verifiable (Can't find the post about it, however)

What do you mean?

What's the use case?

a syndication feed would probably suffice

It would never load due to infinite recursion.

I don't really understand why one would build an HTTP API for this. I can't imagine the database being more than a few megabytes, the whole thing could probably be served as a JSON file.

API doesn't mean someone's else's computer.

APIs are leaky abstractions as all abstractions are.

Not all abstractions are leaky. Not at all.

APIs can be hosted locally. In fact, I think most of them are.

Bummer.

Honestly, Web3 is partially it now. If you remove the hype and buzzwords, you are left with a bunch of individually addressable contracts that can all be composed and integrated together seamlessly under a single web frontend.

I remember years ago doing something as simple as getting a coin onto an alt-chain was a 20 step process. Get the gas coin on the target chain, find the right contract address, bridge the assets over, do a bunch of conversions, finally to get the token on the chain I wanted.

These days its a single click. Different tools or companies have sprung up, and while they use the same exact contracts I would have manually interacted with before, they script them all together into one transaction to save time and gas fees. A simple UI to select destination chain and coin and it handles all the swaps, gas, bridging, etc needed.

You don't need permission and a lot of standards have developed to keep things running smooth.

It's not just coins and crypto either. No reason not to develop other things off the chain too.

I've been working on my own PIM (personal information management) suite and using web3 has been amazing. No need to worry about a server or a database. Just deploy my code to the chain and store all my data encrypted on chain as well. The altchains are extremely cheap and this storage is already backed up, replicated, distributed, and can be local with a self-ran node. I will never lose it and I can bootstrap my data from scratch anywhere in the world as long as I can sync the chain or reach an API. I have todo lists, notes, contact management, and more in the pipeline and I've never felt so safe about my infrastructure or data before.

Algo trading requires expensive APIs that fetch almost realtime bids. There are platforms that provide UPSI as APIs, which these traders use.

AWS is arguably an API, and I shovel a ton of money their way. Stripe is another one, though that ends with me getting paid, so I guess that technically doesn't count unless I start losing money using it. There's also the APIs backing all the apps I pay for, since I don't talk to them via a webpage. But then, if we look at every web page that hits an API to get a list of items to display, instead of that list coming over on the html itself, that'd be an API, technically. ChatGPT is an API I hit a bunch via non-web browser clients that I pay for.

I’ve always liked Insomnia

I just recently (today) started using Bruno, seems pretty good so far. I like that it has a flat file structure that can be included in a git repo.

same

Same here. (U+1F979 Face Holding Back Tears)

I had exactly the same thought at first but then realised they're referring to the collection rather than the APIs. Therefore singular is correct.

You can't sell ads on it.

Maybe you could! Perhaps a sample data API that creates users like "John Chocolate Oreos," address "100 Pack Street", age 19.99, email "visit<at>oreo.com"

In this particular case they seem to pull from https://www.maxmind.com/en/home

There's a bunch of IP/GPS and physical address lookup sites, services, and databases out there.

for basic high-low-open-close daily data, I like yfinance for daily data and polygon.io for minute by minute data

I would say that would be my use case for LLMs. These should be easily fixed by automation that can reason about documentation and could spit out code fixes.

Of course I assume there is documentation that is updated before new changes go live which might be too much to ask :)
