API Endpoint

The format of a MegaNode API endpoint is https://{chain}-{network}.nodereal.io/v1/{API-key}
Here is an example:

https://bsc-mainnet.nodereal.io/v1/4c0a1c23661a4e26bcbcwed461e34ea9

For other chains or networks, you could refer to this guidance Find API key & endpoint.

Example

Request

curl https://bsc-mainnet.nodereal.io/v1/your-api-key \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"txpool_content","params":[],"id":1}'
