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

Overview

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

Authentication

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 Platform and view the there. We offer packages with 10, 20 or 40 requests/sec, and even a custom Enterprise plan.

If you are using the API for free, without an API key, please help us spread the word and use the in your app or website.

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

curl -H 'Authorization: mainnet_xxxxxxxxxxxxxxxxxxxxxxx' \
https://api.whatsonchain.com/v1/bsv/main/chain/info

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

Support

If you need higher rate limits on testnet, please contact us through .
