Was es kann

Return the loopback-only page used to connect a NIP-07 browser extension or an advanced NIP-46 signer.

Eingabe-Schema

{
  "type": "object",
  "properties": {},
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Check whether a user-controlled NIP-07 or NIP-46 signer is connected.

Eingabe-Schema

{
  "type": "object",
  "properties": {},
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Advanced fallback: create a nostrconnect:// URI for the user to scan or open in a remote signer. Never accepts an nsec.

    }
  },
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"

Connect a bunker:// URI only when the user knowingly supplied it. Prefer the local setup page so connection secrets are not placed in chat. Never accepts an nsec.

Forget the in-memory signer session and all prepared events.

Eingabe-Schema

Read the connected Nostr identity's Grynvault supporter, payment, and NIP-05 dashboard using a short-lived signed authorization. This does not create an invoice or change settlement.

  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"

Sign a short-lived, read-only Grynvault account handoff code so the browser tab that created it can receive its own dashboard. This does not create an invoice, publish a Nostr event, change settlement, or grant wallet custody.

Prepare an exact, short-lived signed-authorization request for a one-time donation of 21 to 1,000,000 sats or the fixed 2,100-sat 30-day membership. Does not sign, create, pay, or settle an invoice.

Eingabe-Schema

  "properties": {
    "plan": {
      "type": "string",
      "enum": [

    "plan"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"

{
  "type": "object",
  "properties": {
    "operation_id": {
      "type": "string",
      "format": "uuid"

      "const": true,
      "description": "Must be true only after the user explicitly approved this action."
    }
  },
  "required": [
    "operation_id",
    "confirm_invoice_creation"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Check and normalize a [email protected] identifier, then prepare its exact 2,000-sat invoice authorization. Does not sign, reserve the name, create, pay, or settle an invoice.

Eingabe-Schema

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "minLength": 1,
      "maxLength": 32,
      "pattern": "^[A-Za-z0-9_-]+$"
    }
  },
  "required": [
    "name"
  ],
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

After separate explicit user confirmation, sign the prepared authorization and create exactly one pending 2,000-sat [email protected] invoice. Does not pay, settle, activate, or prove identity.

Eingabe-Schema

{
  "type": "object",
  "properties": {
    "operation_id": {
      "type": "string",
      "format": "uuid"
    },
    "confirm_invoice_creation": {
      "type": "boolean",
      "const": true,
      "description": "Must be true only after the user explicitly approved this action."
    }
