author_pendingExtrinsics – Mythos JSON-RPC Method

Returns all signed extrinsics that have been submitted to the Mythos transaction pool but not yet included in a block. Use this method to monitor congested lanes, replay player reward batches, or debug marketplace listings waiting for inclusion.

Parameters​

This method does not accept parameters.

Returns​

An array of SCALE-encoded extrinsics represented as hex strings. Each entry corresponds to a pending extrinsic.

Request Example​

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

Example Usage (curl)​

curl https://api-mythos-archive.n.dwellir.com/YOUR_API_KEY \
  -H "Content-Type: application/json" \

    "jsonrpc": "2.0",
    "method": "author_pendingExtrinsics",
    "params": [],
    "id": 1
  }'

Notes​

  • Use author_submitExtrinsic or author_submitAndWatchExtrinsic to submit new payloads.
  • Mythos relays large NFT drops—expect short spikes in pool size around event launches.
  • The response is unsigned data; decode extrinsics with the latest runtime metadata for full context.
