qoery - every stat queryable
The 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…

Qoery Python SDKJan 2026 · github.com · ▲11I'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…
- 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…

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)
- CCChainsage – Cryptoasset Market Data2018 · ▲9
Hi everyone, we recently launched our cryptocurrency pricing site we have been working on for a few months: https://chainsage.com Currently we are aggregating data from 200+ exchanges for 2000+ assets. Being cryptocurrency enthusiasts and investors ourselves, we were frustrated with the lack of filtering/sorting options existing providers of similar data had. For example, here's a live dashboard of assets with at least $100k in trading volume and a 10%+ USD price increase in the last 24 hours:…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
