various sports apis:
football (soccer), football (nfl/college), ufc/boxing, car racing, and golf.
if you want really unique api data then you can use space telescope measurements. don't really see the application of that being on the blockchain or in smart contracts but it's interesting. check out irsa star catalogue, gator, simbad.
im jealous of you faggot. you better win this shit
Use time data from a punch in clock to automatically calculate blue collar wages. You could use SAP data for this IRL.
Obituaries, morgue, and tax info for Hitman contracts. Law api for crowdfunded legal cases that pay out to the investors awarded amounts.
something with star data might win with most creative use case of chainlink.
also think tesla (any launch apis?). and environmental telescopes that monitor climate change. you could create a smart contract that anyone can donate to, the funds of which are awarded to companies which verifiably reduce their carbon footprint. a kind of crowdfunding for climate change
$1000 eoy
expanding on this, paying employees their hourly wages at the end of every shift. write a smart contract that uses chainlink to query a database with hours worked in it that will pay out the wages in ethereum once a day at a specified time.
also add functionality that sends the eth to a fiat gateway and market sells it
she likes you senpai
>biz protocol
it should use a chainlink to some kind of array of all the available liquidity in the market in order to buy high sell low
Flight insurance payouts are a much vaunted use case for smart contracts and a nice comfy middle ground between obvious/doable and ambitious imo. They are also great because you can actually aggregate the flight time data from multiple different tracker websites to make full use of aggregation function (vs some other use cases where multiple oracles just check the same API because it's the only source for the data).
Or go full meme and make an IOT oracle for smart toilets.
