rpc_methods

Returns the complete list of JSON-RPC methods the node exposes along with their maximum parameter counts. This is the quickest way to confirm feature availability (e.g., author_rotateKeys, state_queryStorage) on your chosen endpoint.

Parameters

This call does not take parameters.

Returns

Field	Type	Description
result.version	number	JSON-RPC protocol version.
result.methods	array	List of method names supported by the node.

The public Atlantic RPC returned 111 methods when queried on 2 October 2025, including Substrate core namespaces and Atlantic-specific endpoints such as mantaSBT_pull_ledger_diff and zenlinkProtocol_*.

Usage

curl https://api-manta-atlantic-mainnet.n.dwellir.com/YOUR_API_KEY \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0",
    "method": "rpc_methods",
    "params": [],
    "id": 1
  }'

Operational Tips

• Compare the returned list with our docs to spot any methods that require bespoke integration (e.g., payment_queryFeeDetails).
• If a method is missing—such as beefy_getFinalizedHead or grandpa_roundState—the node does not implement it. Plan to remove or hide unsupported functionality in your client UI.
• Re-run this call after runtime upgrades; new pallets may expose fresh RPC extensions.
