  "summary": "This pull request adds a `/rest/txspendingprevout` endpoint to Bitcoin Core's REST interface, mirroring the `gettxspendingprevout` RPC. It supports querying up to 15 outpoints at a time against the mempool and optional `txospenderindex`, with query parameters for `mempool_only` and `return_spending_tx`.",

    "sedited suggested aligning the implementation with the RPC helper structures, adding a maximum limit of 15 outpoints, and testing txospenderindex in the functional test; author addressed all three.",
