Introduction

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

Overview

WhatsOnChain provides access to BSV and BTC 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 to the BSV network.

The supported networks are:

• Mainnet

• Testnet (BSV-only)

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 Teranode Group Platform and view the available subscription plans 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 "Powered by WhatsOnChain" logo in your app or on your 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.

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