Blockchair API provides developers, researchers, and businesses with access to data contained in 17 blockchains. The API supports numerous analytical queries like filtering, sorting, and aggregating blockchain data with high uptime. Blockchair is the first blockchain explorer which incorporates a multitude of different blockchains into one search engine. Unlike most blockchain explorers and cryptocurrency companies, Blockchair does not collect personal data, nor does Blockchair share it with third-party analytics companies and ad networks.
