With QuickNode, you get access to our global network which always routes your API requests to the nearest available location, ensuring low latency and fastest speeds.
Token Authentication - By default, all endpoints created on QuickNode are protected by a token in the URL which looks something like this:
Please note the
/ at the end of the URL. Without it, you will receive
Approved Referrer List - For endpoints on the shared network, you are able to add a list of approved referrers. This requires any HTTP request to send a
Referrer header or any WebSocket request to send a
Origin header populated with one of the referrers you entered into our user panel.
Disabling Token Authentication - You can also disable the token authentication completely in your security settings for a given endpoint. This will allow anyone to make requests to the endpoint without the token.
If you're running a dedicated endpoint, you cannot disable token authentication or roll your token - so be careful where you share your endpoint URL!
JWT (JSON Web Tokens) - For additional security, you can also enable JWT for each of your deployed endpoints. JWT allows for stateless authentication between you and your endpoint. Learn how to use JWT with QuickNode in this step-by-step guide.
Multiple Authentication Tokens - Create multiple authentication tokens for each of your deployed endpoints. This allows you to revoke any tokens that may be comprised, without needing to restart your non-compromised endpoint.
To roll an individual authentication token, create an additional token and then delete the previous token. Learn more about multiple authentication tokens in this QuickNode guide.
Most *nix based systems have cURL support out of the box. cURL is a command line tool and library for transferring data with URLs. Check if you have it by running the following:
Web3.py is a Python library for interacting with Ethereum. If you'd like to use it, please be sure to install it like so:
pip install web3
At QuickNode we prefer ethers.js as our JS library for interacting with JSON-RPCs when possible. Ethers aims to be a complete and compact library for interacting with the Ethereum Blockchain and its ecosystem. If you'd like to use it, please be sure to install it like so:
npm install --save ethers
There is also Web3.js - it's a collection of libraries that allow you to interact with a local or remote ethereum node using HTTP, IPC or WebSocket. If you'd like to use it, please be sure to install it like so:
npm install web3
Eth.rb is a comprehensive ruby library that provides a high-level interface to interact with the Ethereum blockchain, making it easier for developers to manage accounts, send transactions, and work with smart contracts. If you'd like to use it, please be sure to install it like so:
gem install eth
