Yeah sorry... Trying to keep up with everything. I'll get the docs updated by tomorrow!

You send a NIP-98 authenticated request to the server's claim endpoint. The server will respond with your eCash proofs. You can then spend those proofs at the mint to pay an invoice (simply said, withdraw to LN).

You can play around with the reference implementation on https://app.cashu-address.com using NIP-07. If you look at the network tab, its pretty obvious what is happening behind the scenes. 

 Ok thanks!

Will add more details over the course of the day. 

 Thanks, looking at it 

 So after I do /claim I have to go to the mint and ask them to withdraw to my ln address? 

 Claim gives you all collected eCash proofs.

It depends on what you want to do with the eCash. You can claim it inside your own eCash wallet or use it to pay a Lightning invoice. On https://app.cashu-address.com I built flows for both cases 

 Ok thanks, need to learn more about eCash now. 

 No problem. Happy to answer questions at any time. I can also recommend joining the Cashu dev channels (either telegram or discord)
