Guides
All guides- Best SerpApi Alternatives in 2026, RankedThe best SerpApi alternatives in 2026, ranked by price per search, free tier and data source, with every price read from the vendor's own page in October 2026.
- API Response Time: What 99 Public APIs Actually DoWe timed 99 live public APIs. The median answered in 446 ms, the server's own share was 195 ms, and distance mattered more than code. What counts as good.
- The State of Public APIs 2026: Data From 1,580 APIsWe measured all 1,580 public APIs in our directory. How many need a key, OAuth or nothing, which work from a browser, what is growing, and how many are down.
