  3. Show HN: DomeAPI (YC F25) was acquired. pmxt is the open-source equivalent (github.com)

  4. We bootstrapped to 450 stars by giving away risk free arbitrage opportunities

    I maintain pmxt.dev, an open-source unified API for prediction markets (Polymarket, Kalshi, etc.). We essentially built "ccxt for prediction markets." We’ve hit ~450 stars and 30k downloads. We are currently the…

  5. Show HN: Open-source library to unify Polymarket and Kalshi APIs (github.com)

    I noticed prediction markets are becoming fragmented (Polymarket on-chain, Kalshi regulated/off-chain), making it painful to write cross-exchange bots. Crypto has ccxt to standardize exchange APIs, but nothing existed…

  6. Show HN: I built a Python wrapper to query Uniswap v3 directly (github.com)

    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…

  8. Show HN: I built a crypto data API that ignores CEXs to cut costs by 85% (qoery.com)

    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…

  9. Show HN: 85% Cheaper Crypto Data (qoery.com)

    If you've ever tried to integrate crypto market data into an app, you know the pricing for commercial APIs gets crazy fast. I couldn't justify the cost for my projects, so I built my own solution. I learned to index and…

  10. Show HN: Mintlify Ignored This Feature Request for 6 Months. Here's My Solution (github.com)

    Mintlify users have been begging for pre-filled API playground fields for months. The GitHub discussion has people literally saying "I just lost two hours of my day banging my head against this issue."…

  15. Show HN: Query 50M statistics in plain English (qoery.com)

    Hey HN, We built qoery because we were tired of downloading CSVs from the World Bank, Eurostat, OECD, and a dozen other portals every time we needed a simple statistic. Now you can just ask "What's France's GDP growth…

  16. Show HN: StrateQueue- Bridge backtest and live trading with microsecond latency (github.com)

    My co-founder and I applied to YC this summer with a full quant platform - backtest, optimize, and deploy strategies all in one place. Regulatory complexity killed us. We had to pivot. While my co-founder moved on to…
