401/402 Unauthorised/Payment Required Nostr HTTP AUTH Flow

draft optional author:wakoinc

This NIP is an extension to NIP-98 which allows HTTP authorization using a base64 encoded event header. This NIP documents a typical protocol flow for failure, retry and success - or hard fail.

Nostr Service Definition

draft optional author:wakoinc

A standardised service definition event allowing services to broadcast services they provide, and client apps to impliment support for a service type that is inter-changable

require 'sinatra'

get '/public/AUTHIMAGE.jpg' do
  auth_header = request.env['HTTP_AUTHORIZATION']
  puts auth_header

  # Check if the header value starts with "Nostr "
  unless auth_header && auth_header.start_with?("Nostr ")
    headers['WWW-AUTHENTICATE'] = 'NOSTR-NIP-98'
    headers['Access-Control-Expose-Headers'] = 'WWW-Authenticate'

Nostr 'My Services' Event Kind (Draft/Experiment)

A way to support in-app management of services with subscriptions and credits where a payment is due (I guess it can be free too?).

Client UX

A client app can query for these events and show a list of services that are active or have credit remaining. They can show a list of expired (or no credit left) services as well. Clicking a service can allow you to make a payment based on the payment options provided.

What to support

• Current balance (optional if expiry exists, else mandatory)
• Current expiry (optional for balance): Represents payment due by

Pain Points / design limitations

• Limit is useless for subscriptions with multiple filters (as how to prioritise which filter results are most important? Left to right?)
• Hard to do pagination (using since/until, but what limit to use? What if older events shared after you fetch, you’ve now missed it)
• Race condition between EOSE and CLOSE subscription when you don’t want to stream (option to only return existing data only, without newer broadcast results)
• Events from new pubkeys are missing basic kind0 data (ideally embed name/display_name for first pubkey event)
• Websocket congestion control and bottlenecks (single event streamed at a time, blocked by larger events FIFO)
• Unable to query for ranges of kinds (e.g. {"kinds": [30000-39999]})
• More?

draft optional author:wakoinc

This NIP defines a way for clients to request a target proof of work calculation for an event prior to publishing.
