Congrats on the launch 🚀 I love that it's just one request and I also love the design of the website! I do have a question tho, how did you come up with the name? A quick Google shows "a green or yellow aromatic citrus fruit whose acidic rind and juice are often used in Japanese cuisine." but what does it have to do with the value of stocks and coins 🤔

@daniel_langezaal Good question! I wish the answer were more interesting, but honestly we just thought Yuzu was a fun name and also the domain was available 🤓

@daniel_langezaal @steve_coffey now we’d better make it the juiciest api out there 🍋😀

@steve_coffey I can totally relate to that naming process, haha!

@steve_coffey @katerina_opocenska Agree, it's a juicy api for prices of currencies and stucks!

👋 Hello Product Hunt fam! I’m Steve, and I’m excited to announce the launch of Yuzu - the market data API we always wished we had. 🤔 The problem Simply put, there aren't any market data APIs built for rapid app development. The rigid structure of traditional market data APIs requires a lot of up-front work to build up a sufficient dataset before any of the real work can begin. A little backstory: before Yuzu, we built another product: a consumer-facing portfolio tracking app. This meant we needed to have prices on hand for every stock, crypto, ETF, mutual fund, and option, with history going back 30 years, which was a ton of work! But having the data in our own database exposed us to another class of issue: ongoing data maintenance. Frequent stock splits and ticker symbol changes were a headache and distracted us from focusing on building a great user experience. We believe that anyone wanting to build with market data should be able to quickly prototype and scale their app to thousands of users without any scraping, data pipelines, or ongoing data maintenance. With that goal in mind, we’re excited to launch Yuzu with our two initial products: 🕸 A robust, high-performance GraphQL API A common use case for investing apps, portfolio trackers and analytical platforms is displaying multiple assets at once and showing their historical performance. With traditional REST APIs, this requires multiple API calls and can be a slow experience for users. The common solution is to cache this data internally for quick client rendering, but this uncorks another problem: managing the daily deluge of stock splits and ticker symbol changes in the market. The last thing you want is your customers waking up to see Converted Organics instead of Coinbase on IPO day (this really happened). Using GraphQL, you can skip the in-house database and query all the data you need in one API call, directly from your frontend. Try it out! https://graph.yuzu.dev/graphql 🚿A streaming API for prices, quotes, and aggregates The market changes minute-to-minute, and apps should be engaging, real-time, and responsive to market events. But if your market data API limits you to one websocket connection, it means proxying that connection through your own infrastructure and back out to all your clients, forcing you to take on a massive infrastructural workload. We’re out to change that. Now, you can get live prices in your app in just 5 lines of code. With no limit on the number of connections you can make, you can stream data from Yuzu directly to your app without dealing with the DevOps.

@steve_coffey WHOA this is awesome, going to use this for my next fintech app :D

Whoa! This is awesome, I've been avoiding building apps involving stocks/crypto/etc because I didn't want to be making all those API calls and having to maintain the data. Can't wait to to give it a go!

@rhuwell Thanks for your support! We're excited to hear your feedback

Yuzu focuses on the real challenges a Fintech app faces when building the data feed. For example, having a way to know delisted stocks or ticker changes can eliminate a lot of backend work. Super excited to explore their APIs.
