   Please describe the feature you’d like to see added.

   I can’t find any docs on how you parse services results for getnodeaddresses RPC data requests:

   https://bitcoincore.org/en/doc/30.0.0/rpc/network/getnodeaddresses/

   I’m hoping to have a more user friendly interface, other than the raw services number for a geolocation search filter:

   Is your feature related to a problem, if so please describe it.

   No real problem, other than lack of documentation, to understand how this data can be parsed into a user friendly summary.

   Describe the solution you’d like

   Documentation on parsing the raw data.

   Describe any alternatives you’ve considered

   None.

   Please leave any additional context

   Live working demo here (to better understand my interfacing): https://dragonfrugal.org/open-crypto-tracker/plugins.php#plugin_on-chain-stats

   It’s a bitfield, defined here:

   https://github.com/bitcoin/bitcoin/blob/0690514d4f72aac251ee0b876cded9187d42c63e/src/protocol.h#L308-L339

   You’re right that it’s not super well documented but you can find some information:

   Thanks for pointing me in the right direction @pinheadmz. 👍 Googling didn’t get me too far.

   I’m looking to filter mining, ln, etc (if possible), in the geolocation GUI results filters. Hopefully this is possible. Will deep dive your source file and 3rd party links this week, thanks very much.

   I can close this issue, unless you all think it’s feasible enough to keep open? I’m sure their are a ton of higher priorities, I just came up nearly blank on google, so figured I’d ping it here. Thanks for the quick response.

   I see the source seems to suggest only P2P-related stuff is flagged into the services value, if I’m reading it right.

   Seems I may need to look at other endpoints for the data I seek. Was hoping to keep overhead low with a single call to getnodeaddresses, as this will be run on low power devices on home / internal networks often…but doesn’t look like I can do that.

   Bitcoin nodes have no knowledge about what other functionality may run on top, like LN or mining. The “services” the P2P node network knows about only relate to functionality offered over that P2P network.
