Search OP_RETURN https://bitcoin.stackexchange.com/questions/36478/how-can-i-search-for-op-return-data
OK - smartbit Has an API. I can search for the OP_RETURN value by using curl:
{ “success”: true, “results”: [ { “type”: “transaction”, “data”: “d1d90a5730f0a596dfa4b83e167b02801a74273ffd0cf21e419c3f04ffb3e6df” } ], “search”: “d1d90a5730f0a596dfa4b83e167b02801a74273ffd0cf21e419c3f04ffb3e6df” }
The return value includes the transaction. Then
{ “success”: true, “transaction”: { “txid”: “d1d90a5730f0a596dfa4b83e167b02801a74273ffd0cf21e419c3f04ffb3e6df”, “hash”: “d1d90a5730f0a596dfa4b83e167b02801a74273ffd0cf21e419c3f04ffb3e6df”, “block”: 674803, “confirmations”: 1114, “version”: “1”, “locktime”: 0, “time”: 1615853224, “first_seen”: 1615852887, “propagation”: null, “double_spend”: false, “size”: 266, “vsize”: 266, “input_amount”: “0.04228154”, “input_amount_int”: 4228154, “output_amount”: “0.04201022”, “output_amount_int”: 4201022, “fee”: “0.00027132”, “fee_int”: 27132, “fee_size”: “102.00000000”, “coinbase”: false, “input_count”: 1, “inputs”: [ { “addresses”: [ “1Stampap27ZbxugEmWPbxNXJxzmYWn2op” ], “value”: “0.04228154”, “value_int”: 4228154, “txid”: “95aa750d9e365651646497407cad5cecfc9e372fa8e1d699a86f9d1357a18ba2”, “vout”: 1, “script_sig”: { “asm”: “304402202acfdc5fe6de4971970509e5d24e4c7622cbdd76cb13d85f2e3ecb21ae20de7402201e33ef5f9a0f0278eb22a8f4149096f6dc4c627f3d47ba50c35c51918f95957281 048997ba70cd2005b4e2f21bba96b6fdf8268cd503cb5de2223ee1511780a50936c9403ef6a6e087dad88e88721ad5725938f104e969baff2b4ddac9ab57d2a0c5”, “hex”: “47304402202acfdc5fe6de4971970509e5d24e4c7622cbdd76cb13d85f2e3ecb21ae20de7402201e33ef5f9a0f0278eb22a8f4149096f6dc4c627f3d47ba50c35c51918f9595728141048997ba70cd2005b4e2f21bba96b6fdf8268cd503cb5de2223ee1511780a50936c9403ef6a6e087dad88e88721ad5725938f104e969baff2b4ddac9ab57d2a0c5” }, “type”: “pubkeyhash”, “witness”: [ “NULL” ], “sequence”: 4294967295 } ], “output_count”: 2, “outputs”: [ { “addresses”: [], “value”: “0.00000000”, “value_int”: 0, “n”: 0, “script_pub_key”: { “asm”: “OP_RETURN bf6eec9f213846a53ed187d41d2b9ed2e954649a45d2883e5df6b107b2eb0b75”, “hex”: “6a20bf6eec9f213846a53ed187d41d2b9ed2e954649a45d2883e5df6b107b2eb0b75” }, “req_sigs”: 0, “type”: “nulldata”, “spend_txid”: null }, { “addresses”: [ “1Stampap27ZbxugEmWPbxNXJxzmYWn2op” ], “value”: “0.04201022”, “value_int”: 4201022, “n”: 1, “script_pub_key”: { “asm”: “OP_DUP OP_HASH160 04e575307e92a334979d5198cda84d974b3ab20b OP_EQUALVERIFY OP_CHECKSIG”, “hex”: “76a91404e575307e92a334979d5198cda84d974b3ab20b88ac” }, “req_sigs”: 1, “type”: “pubkeyhash”, “spend_txid”: “5222827cad650b0b4a4537255152429ae60c69fa74cee3d023644c13e5b1344b” } ], “tx_index”: 625893340, “block_index”: 765 } }
