Hey HN, I built this because I kept hitting the same problem: getting stock data into side projects was either expensive (Polygon starts at $199/mo) or unreliable (Yahoo Finance scraping breaks constantly).
stockdata.dev is a REST API for 15-minute delayed US stock data. 10,000+ tickers, historical daily prices, batch quotes. Free tier is 1,000 calls/month. You can grab a trial API key right on the docs page - no signup required, works for 24 hours.
I built it to power my other project, https://dirtytraders.app, which tracks stock trades made by members of Congress. Needed a reliable, affordable data source for quote lookups and portfolio tracking — couldn't find one that fit, so I built my own and opened it up.
Stack: Flask/Gunicorn, PostgreSQL, Redis, InfluxDB. Three data providers with automatic fallback (IEX Cloud - Alpha Vantage - Finnhub). S&P 500 quotes are pre-cached, everything else is fetched on demand and cached for 15 minutes.
The 15-minute delay is intentional - no exchange licensing fees, which is how I can offer a free tier. Covers the vast majority of use cases: portfolio trackers, trading bots, dashboards, alerts.
Pricing: Free (1k/mo), Starter $15/mo (50k), Pro $50/mo (500k).
Would love feedback on the API design, docs, or pricing. What would make this more useful to you?
Are you consuming the data directly from the exchanges? If so, which ones? Or is this just a proxied API to the services you listed as fallback?
IEX Cloud shut down like 18 months ago so it's rather alarming that its listed.
If you're not licensed with any exchanges to redistribute this data (which you must be..), you are contributing to why the data is expensive from legitimate vendors in the first place.
Good catch on IEX Cloud - that's stale documentation from an earlier version. We actually pivoted away from stock quotes entirely. stockdata.dev now serves SEC EDGAR filing data (financial statements, insider trades, institutional holdings, company filings). All sourced directly from SEC's public EDGAR APIs - no exchange data, no licensing required. We should clean up any remaining references to the old quote product. Thanks for flagging it.
