How to Access Polygon via Ethereum API

Step 1: To access Polygon via Ethereum, use the native access endpoint with http-rpc at the end:

• Network: Polygon Mainnet
• Request Type: POST

https://svc.blockdaemon.com/polygon/mainnet/native/http-rpc

• Network: Polygon Amoy
• Request Type: POST

https://svc.blockdaemon.com/polygon/amoy/native/http-rpc

Step 2: Authenticate your request using your API key. You can include the API key using either of the following headers:

Authorization: Bearer YOUR_API_KEY

X-API-Key: YOUR_API_KEY

Step 3: Specify an Ethereum method in the request body:

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "YOUR_METHOD",
    "params": []
}

Example Request

Here is a cURL example for using eth_blockNumber to get the current block number in Polygon Mainnet:

curl -X \
POST https://svc.blockdaemon.com/polygon/mainnet/native/http-rpc \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": []}'

The following is a typical response you will get:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": "0x22105c3"
}

Here is a cURL example for using eth_gasPrice to get the current block number in Polygon Mainnet:

curl -X \
POST https://svc.blockdaemon.com/polygon/mainnet/native/http-rpc \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"jsonrpc": "2.0", "id": 1, "method": "eth_gasPricer", "params": []}'

The following is a typical response you will get:

{
  "jsonrpc": "2.0",
  "id":1,
  "result": "0x1dfd14000" 
}
