Guardian Open Platform vs Finnhub: overview
Guardian Open Platform
The Guardian's Open Platform gives developers the same content API that runs the Guardian's own sites, with full article bodies, tags and sections going back to 1999. A free developer key is commonly reported at about 5,000 calls a day and 12 calls a second, and it is meant for non-commercial projects. Commercial use needs a separate agreement with Guardian News & Media. Clean, consistent tagging has made it a favourite for teaching and research, though you only ever get one publisher.
Finnhub
Finnhub is a New York fintech founded in 2018, according to CB Insights, that sells stock, forex and crypto data over REST and WebSocket, with staff reported in New York, Mumbai, Sydney and Ho Chi Minh City. News is one feature among many. A free key returns a year of North American company news and general market headlines at up to 60 calls a minute, but it is meant for personal, non-commercial use, and low-latency news streaming is a premium feature. Commercial data bundles are priced on Finnhub's site, with the All-in-One plan listed at $1,000 a month.
