  • @jtgrassie thanks for answer but I get a empty txid in JSON response from /get_outs Jul 27 at 14:43
  • @jtgrassie ok, nevermind I have not noticed in documentation there is "get_txid" param, thanks a lot! Jul 27 at 15:16

    jtgrassie, you probably want to add that as an answer ?

    I wouldn't say "fun fact", rather it just show's I missed typing the param in the example. Glad you're sorted now anyway.

You can use the RPC method get_outs with the input parameter get_txid set to true.

A concrete example:

$ curl -X POST http://127.0.0.1:18081/get_outs \
    -d '{"get_txid":true,"outputs":[{"index":5164903},{"index":7719180}]}' \
    -H 'Content-Type: application/json'
