Guardian Open Platform vs Finnhub: overview
Guardian Open Platform
The Guardian's Open Platform exposes the same content API that powers the Guardian's websites and apps. A free developer key returns full article bodies with tags and sections back to 1999, and commonly reported limits are about 5,000 calls a day and 12 a second. The key is for non-commercial projects; commercial use needs a deal with Guardian News & Media. Developers like it for teaching because the tagging is consistent and the responses are predictable, which makes it a good dataset for NLP exercises. The obvious limit is that every article comes from one newspaper.
Finnhub
Finnhub is a New York fintech founded in 2018, according to CB Insights, with staff reported in New York, Mumbai, Sydney and Ho Chi Minh City. It sells stock, forex and crypto data over REST and WebSocket, and news is one endpoint among many. The free key is generous on rate (60 calls a minute) and returns a year of North American company news plus general market headlines, but it is for personal, non-commercial use, and low-latency news streaming is a premium feature. Official SDKs cover Python, Go, JavaScript and more. Commercial bundles are priced on the site, with All-in-One listed at $1,000 a month.
