Blockchair API provides developers with access to data contained in 18 different blockchains. Unlike other APIs, Blockchair also supports numerous analytical queries like filtering, sorting, and aggregating blockchain data.
Here are some examples of what you can build using our API:
A wallet supporting multiple blockchains (request transaction, address, xpub data, and also broadcast transactions)
An analytical service showing some blockchain stats and visualizations
A service tracking the integrity of your or your customers' cold wallets
A solid academic research
Some fun stuff like finding the first Bitcoin block over 1 megabyte in size
For some tasks like extracting lots of blockchain data (e.g. all transactions over a 2 month period) it's better to use our Database dumps feature instead (see https://blockchair.com/dumps for documentation) — it's possible to download the entire database dumps in TSV format and insert the data onto your own database server (like Postgresql or whatever) to further analyze it.
Almost every API endpoint description is accompanied with an example visualization of the data on our website (https://blockchair.com), and it's also worth it to note that the website is working completely using our API (yes, even the data for charts is pulled from one of our endpoints, and it's fully customizable).
Blockchair cares about user privacy, we neither collect nor share with anyone your personal data rather than for statistical purposes. That includes using the API as well. Please refer to our Privacy policy: https://blockchair.com/privacy. Please also check out our Terms of service available here: https://blockchair.com/terms — by using our API, you are agreeing to these terms.
