Get a directory receipt ending at a specific height

Not yet available on MainNet

The includeReceipt supports fetching an anchor that ends at a specific height of the root anchor chain. For example, replacing "includeReceipt": true with "includeReceipt": { "forHeight": 123 } attempts to return a receipt anchored at root chain entry 123.

Get a receipt for a specific DN anchor

Not available yet on MainNet

1. Given a DN anchor

   curl http://127.0.1.1:26660/v3 -X POST -s --data-raw '{"jsonrpc": "2.0", "id": 1, "method": "query", "params": {"scope": "dn.acme/anchors", "query": { "queryType": "chain", "name": "main", "index": 15 }}}' | jq .result.value.message.transaction

     },
     "body": {
       "type": "directoryAnchor",
       "source": "acc://dn.acme",
       "minorBlockIndex": 44,
       "rootChainIndex": 72,
       "rootChainAnchor": "21b157d9d0fe394c3cedcfdd3dc77a32b88c74185440d9c5c3e98e0f1d33becd",

       "makeMajorBlockTime": "0001-01-01T00:00:00Z"
     }
   }

2. And a transaction

   curl http://127.0.1.1:26660/v3 -X POST -s --data-raw '{"jsonrpc": "2.0", "id": 1, "method": "query", "params": {"scope": "5eee79bf10e13d26532067ff93473aced45e68942f4cc58e/ACME", "query": { "queryType": "chain", "name": "main", "index": 0, "includeReceipt": true }}}' | jq .result.recei

   {

     "localBlock": 18,
     "localBlockTime": "2024-04-18T17:51:48Z"
   }

3. Fetch a receipt starting with the previous receipt's anchor and ending at the target anchor's root chain index

   curl http://127.0.1.1:26660/v3 -X POST -s --data-raw '{"jsonrpc": "2.0", "id": 1, "method": "query", "params": {"scope": "dn.acme/anchors", "query": { "queryType": "anchorSearch", "anchor": "63891df81e9cd2b94a1027eb5d3d05554aff9824a4bcb24da44c2448e7f2a8a9", "includeReceipt": { "forHeight": 72 } }}}' | jq .result.records[0].receipt
