Polkadot is a blockchain platform that enables the creation of a network of interoperable and secure specialized blockchains called parachains. It aims to solve traditional blockchain networks' scalability, interoperability, and governance issues by facilitating seamless communication between blockchains while maintaining high-security standards.
You can connect to polkadot using Blockops public API endpoints. These endpoints are only suitable for testing. Public RPC endpoints are not intended for dApp building. (Throughput rate limited to 50 rps).
To avoid rate limiting and service interruption, to get your own API key.
For Polkadot Mainnet
For Polkadot Westend
The below example uses the public API endpoint to make a request on the terminal
Using curl
Using API keys on an RPC node provides better tracking and monitoring of API usage.
Secure your data, speed up your queries, and take control of your API usage with our RPC API endpoint and personalized API keys. to get your own API key.
To get your API key, create a project using a unique Identifier as the project name and select Polkadot from the network options.
Open the project to view your api key and rpc endpoints.
Connect via Command Line
You can connect to the network using websocket or HTTP with your API key in two ways:
Adding the API key as a query string ?api_key=${APIKEY}
Or the request header -H 'authorization: APIKEY ${APIKEY}'
Curl
For example, the following CURL command can be used to get header and body of a relay chain block.
Here is the response you will receive back.
Wscat
If you want to send data requests with WebSockets, you can use several libraries or wscat. You can install and use wscat as follows:
Install wscat by running the following command: npm install -g wscat
You can connect to the network with wscat using two options by adding the API key as a query string.
Or the request header.
After executing the command, the terminal will display a message indicating that the connection has been enabled successfully.
Then, you can send the following request:
Download wscat from
