redshift 860266ab0e fix: announce provider as soon as the NSEC is saved

A node runner who configures the NSEC through the admin UI (rather than the
NSEC env var) was never announced. The kind 38421 publish task was only
created at boot, gated on an NSEC already being present: saving the key
stored it and updated the live settings singleton, but nothing re-launched
the task, so the provider stayed invisible on relays until the process was
restarted.

Start the task unconditionally and restructure announce_provider into the
idle-and-re-read loop that publish_usage_analytics already uses: it waits
while there is no NSEC, re-derives the identity whenever the key changes,
and re-reads endpoints, mints and relays every iteration. The long
re-announce sleep is now ticked so a replaced identity is announced
promptly instead of up to 24h later. Relay backoff state is hoisted so it
survives an idle poll, a full cycle and an identity change.

This also covers the cases that previously killed the task until a restart:
an invalid NSEC, or a node with no reachable endpoint (HTTP_URL left at its
http://localhost:8000 default and no onion address) now idle and recover as
soon as the configuration is fixed.

Discovery

Routstr uses Nostr as a decentralized directory for service discovery. Your node announces its presence, models, and pricing on Nostr relays, allowing clients to find you without a central server.

How It Works

Provider Advertisement (Kind 38421): Your node periodically publishes an event with its URL, models, and pricing
Client Discovery: Clients query relays for these events to find suitable providers

When announcements are published

Your node publishes an advertisement as soon as it has both a Nsec and at least one reachable endpoint (a public HTTP_URL, or an .onion address). Saving the Nsec in the dashboard is enough — the announcement follows within a minute, and no restart is required. After the first publish it re-announces every 24 hours, and immediately whenever the Nsec, endpoints, mints or relays change.

A node that has no Nsec yet simply waits, and starts announcing the moment one is configured. Note that HTTP_URL defaults to http://localhost:8000, which is not a reachable endpoint: a node with the default value and no onion address has nothing to advertise and will not publish until one is set.

Configuration

Configure discovery in Dashboard → Settings → Nostr.

Required Settings

Field	Description
Npub	Your node's public identity (clients use this to verify your node)
Nsec	Your node's private key (used to sign advertisements)
Relays	Where to publish your announcements

Default Relays

If not configured, Routstr publishes to:

wss://relay.damus.io
wss://relay.nostr.band
wss://nos.lol

Advertisement Format

Your node publishes events like:

{
  "kind": 38421,
  "content": {
    "name": "My Routstr Node",
    "description": "Fast GPT-4 access via Lightning",
    "endpoints": {
      "http": "https://api.mynode.com",
      "onion": "http://xyz...onion"
    },
    "models": ["gpt-4", "claude-3-opus"],
    "pricing": { ... }
  },
  "tags": [
    ["d", "routstr-provider"],
    ["g", "US"]
  ]
}

Tor Integration

If you're running with Tor (see Tor Support), your .onion address is automatically included in announcements. This allows clients to connect anonymously.

Verify Your Announcements

Check if your node is broadcasting:

Copy your Npub
Search on Nostr.band or Primal
Look for Kind 38421 events

Generating Keys

If you don't have a Nostr identity:

Use any Nostr client (e.g., Primal, Damus)
Create an account
Export your keys (npub and nsec)
Enter them in the dashboard

Or generate keys programmatically:

from nostr_sdk import Keys

keys = Keys.generate()
print(f"npub: {keys.public_key().to_bech32()}")
print(f"nsec: {keys.secret_key().to_bech32()}")
