Qoery Python SDK
I'm a university student and needed DeFi data for my project. CoinGecko's API pricing was way out of my budget (like, not even close). $35+/month just for high-granularity data – and that's not even minute-by-minute! So I did what any broke student would do – I started querying the blockchain directly instead. Turns out, going straight to the source is not only cheaper, but I could offer the same data for more than 50% less than traditional providers. So I built Qoery, a Python SDK that makes DeFi data actually affordable for students, indie devs, and anyone building side projects. What…

qoery - every stat queryable2025 · qoery.com · ▲8The current pricing for crypto data APIs (CoinGecko/CMC) is based on a legacy requirement: maintaining hundreds of real-time websocket connections to centralized exchanges (Binance, Coinbase, Kraken, etc.). That infrastructure is heavy, expensive, and requires constant maintenance to filter wash-trading and normalize order books. But if you are building for DeFi, that data is technically irrelevant. The "real" executable price is on-chain (Uniswap, Raydium, Curve). I realized that if I just ignored the CEXs entirely and only indexed the blockchain, I could drop the cost basis by an…

Hi there HN, just wanted to share a little project I've been working on for some time: a coinmarketcap.com Python (API) wrapper. As coinmarketcap does not provide any API endpoints, the code is pretty dirty and should be considered as a scraper more than a real API wrapper. Example usage: >>> import coinmarketcap >>> coinmarketcap.market_cap('bitcoin') $ 7,644,402,276 Everything is well documented in the README but if you have questions, don't ask. Hope you enjoy it, issues and PR on Github are more than welcome. (https://github.com/c0ding/coinmarketcap-api)

- POPrice Oracle for Decentralized Finance Apps2019 · ▲7
We built a data feed oracle to write prices on-chain, and it’s live on the Ropsten test network! In Decentralized Finance (Defi), you can build your own financial instruments and you often need an oracle to write off-chain prices onto the blockchain. We built an oracle focused on data feeds because the current options are too expensive and slow for regularly, repeating data. This oracle is designed for price feeds and uses public key encryption to validate the data submitted is accurate. We modeled our oracle off of MakerDao and generalized the design to work with any datafeed. We’re…

I know everyone is a bit burned out on blockchain and cryptocurrency related stuff around these parts, but I've been working on as a side project for the last few months and thought you guys might be interested: https://cryptoempire.io/ It's still a bit buggy and incomplete (the mobile ux needs a lot of work, the leaderboard isn't functional yet, etc.), but I've reached a point where I'm not totally ashamed of sharing it :) Any feedback would be most welcome!
I can't write Python. It works anywayApr 2026 · github.com · ▲9Read an article about analyzing Garmin data with AI. Sounded great — except I didn't want to send my health data to any cloud service. So I asked Claude to write me 2-3 scripts and a dashboard. This escalated a bit. 30 days and 20$ later I have this: A local-first Garmin archive with interactive HTML dashboards, Excel exports, weather and pollen context, AES-256 encrypted token storage, and a self-healing data pipeline with 515 automated tests. Windows desktop app, no terminal needed. Nothing leaves your machine. I never wrote a line of Python. I understood the problems and made the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
