MarketAux vs The Guardian
Marketaux focuses on financial and stock-market news, tagging articles with entities, tickers, and a -1 to +1 sentiment score across over 200,000 entities and 5,000+ sources in 30+ languages. The free plan allows 100 requests/day returning up to 3 articles each; paid Basic through Pro 50K tiers raise both the daily request cap and articles-per-request limit, plus unlock the entity-level Market Stats endpoint. Access is JSON over a single API-key parameter.
The Guardian's Open Platform serves the publication's own articles, tags, and section metadata across more than 1.9 million pieces of content, with a free Developer key limited to 1 call/second and 500 calls/day for non-commercial projects. A separate Commercial key removes those caps for a usage-based fee and adds images, audio, and video. Requests are authenticated with an API key and return JSON by default, with an XML format option available.
