How does one query the OpenAlias DNSSEC to return an XMR address in Javascript?

Question

Is there an example of how one would query the OpenAlias DNSSEC to return an XMR address for a registered alias? And how would one reference an OpenAlias address like http:// ? OA:// ?

Answer 1

To query OpenAlias is to simply perform a DNS query on TXT records for a given domain. These queries can be secured by utilizing DNSSEC.

Full details of implementing (and more) is all documented at https://openalias.org

Answer 2

You can use the following: https://dns-api.org/

Example output:

https://dns-api.org/TXT/openalias.org

Then use whatever programming language to parse through each TXT transaction and detect the oa prefix and then process each one.

Using the above api calls. I made a chrome extension to output open alias addresses by listing out openalias:// or oa:// handlers like this:

oa://donate.getmonero.org openalias://openalias.org

The chrome extension is here: https://chrome.google.com/webstore/detail/blockchain-gateway/mcppmdjlghmadabjofodajpppiloembp
