rpc_methods - JSON-RPC Method

Description

Returns the list of RPC methods supported by the connected Enjin Matrix node. This is useful for capability detection and for confirming that chain-specific namespaces (e.g., fuelTanks_*, ismp_*, multitokens_*) are available.

Parameters

This method does not require parameters.

Returns

Field	Type	Description
methods	array	Array of method names (strings)

Request Example

Code Examples

cURL

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

JavaScript

const { methods } = await fetch('https://api-enjin-matrixchain.n.dwellir.com/YOUR_API_KEY', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ jsonrpc: '2.0', method: 'rpc_methods', params: [], id: 1 })
}).then((res) => res.json()).then((body) => body.result);

console.log(methods.filter((m) => m.startsWith('fuelTanks_')));

Notes

• fuelTanks_*, multitokens_*, and ismp_* provide Matrix-specific functionality such as fee sponsorship, NFT claimables, and interoperability primitives.
• Some experimental RPCs may require custom type registries (API/INIT: RPC methods not decorated warnings in Polkadot.js). Extend the API with type definitions if they are omitted.
• Use this method during application startup to log the RPC surface area and detect configuration drift between nodes.
