Public Endpoints
Candide provides public endpoints for our Bundler and Paymaster. No API required. Available on mainnets and testnets.
Endpoint URL Format
All our public endpoints use the same simple URL format. Just add the chain ID for the network you want to use.
Base URL:
https://api.candide.dev/public/v3/
Example (Sepolia Testnet - Chain ID 11155111):
https://api.candide.dev/public/v3/11155111
Solana: use the network name instead of a chain ID. These serve the Solana Paymaster API.
https://api.candide.dev/public/v3/solana

Supported Methods
See the list of the Bundler API, Paymaster API, and Solana Paymaster API.
Rate Limit
To keep things running smoothly for everyone, we limit the number of requests you can make from a single IP address. If you send too many requests, you'll get a Too Many Requests error.
Need Higher Limits? For production use or higher rate limits, signup on Candide's Dashboard to get your own Bundler and Paymaster URLs. See API Keys & Endpoints for the URL format and setup.
