This API accompanies the WhatsOnChain.com website to form a suite of blockchain explorer services run on fully independent infrastructure.


WhatsOnChain provides access to Bitcoin SV blocks, transactions, address activity, on-chain data, stats, insights, and much more via a simple REST API.

You can also use this API to broadcast transactions.

The supported networks are:

  • Mainnet

  • Testnet

  • STN


At this stage no authentication is required to use the API up to 3 requests/sec. If you need more, see below on how to increase your rate limit using an API key.

Rate Limits

Up to 3 requests/sec is free. Need more? Please create a free account on the TAAL Platformand view the available subscription plans there. We offer packages with 10 requests/sec, 20 requests/sec, or custom Enterprise plans.

Once you get your API key from the Platform, here is a usage example:

curl -H 'Authorization: mainnet_xxxxxxxxxxxxxxxxxxxxxxx' \

Please make sure to replace mainnet_xxxxxxxxxxxxxxxxxxxxxxx with your actual API key.
