Serper Google News vs Diffbot: overview
Serper Google News
Serper is a Google search API that many agent frameworks list as a default search tool, and it can return Google News results as well as web results. Signup needs no card and comes with 2,500 free queries, which third-party write-ups describe as a one-time allowance. Billing is in prepaid credits: one credit for up to 10 results, two for up to 100. A third-party pricing breakdown lists packs from $50 for 50,000 credits, valid for six months, and one report says the public pricing page was offline in mid-2026, so check the figures in your account. The company behind it publishes little about itself, and like any Google-scraping API it returns titles, snippets and links instead of article text.
Diffbot
Diffbot, founded by Mike Tung in 2008 and based in Menlo Park, California, has an estimated 30–40 staff. Point its Article API at any news URL and it returns title, author, date and clean text without a site-specific parser, and Crawlbot can follow a list of publishers you choose. Its Knowledge Graph links articles to companies, people and topics, so it can also be queried as a news source. The free plan includes 10,000 credits at five calls a minute, Startup costs $299 a month for 250,000 credits, and each exported Knowledge Graph entity costs 25 credits. It works best when you want to build your own news collection from chosen sites.
