-# NWC Client CLI Tool
-
-A command-line interface tool for making calls to Nostr Wallet Connect (NWC) services.
-
-## Overview
-
-This CLI tool allows you to interact with NWC wallet services using the methods defined in the NIP-47 specification. It provides a simple interface for executing wallet operations and displays the JSON response from the wallet service.
-
-## Usage
-
-```
-nwcclient <connection URL> <method> [parameters...]
-```
-
-### Connection URL
-
-The connection URL should be in the Nostr Wallet Connect format:
-
-```
-nostr+walletconnect://<wallet_pubkey>?relay=<relay_url>&secret=<secret>
-```
-
-### Supported Methods
-
-The following methods are supported by this CLI tool:
-
-- `get_info` - Get wallet information
-- `get_balance` - Get wallet balance
-- `get_budget` - Get wallet budget
-- `make_invoice` - Create an invoice
-- `pay_invoice` - Pay an invoice
-- `pay_keysend` - Send a keysend payment
-- `lookup_invoice` - Look up an invoice
-- `list_transactions` - List transactions
-- `sign_message` - Sign a message
-
-### Unsupported Methods
-
-The following methods are defined in the NIP-47 specification but are not directly supported by this CLI tool due to limitations in the underlying nwc package:
-
-- `create_connection` - Create a connection
-- `make_hold_invoice` - Create a hold invoice
-- `settle_hold_invoice` - Settle a hold invoice
-- `cancel_hold_invoice` - Cancel a hold invoice
-- `multi_pay_invoice` - Pay multiple invoices
-- `multi_pay_keysend` - Send multiple keysend payments
-
-## Method Parameters
-
-### Methods with No Parameters
-
-- `get_info`
-- `get_balance`
-- `get_budget`
-
-Example:
-```
-nwcclient <connection URL> get_info
-```
-
-### Methods with Parameters
-
-#### make_invoice
-
-```
-nwcclient <connection URL> make_invoice <amount> <description> [description_hash] [expiry]
-```
-
-- `amount` - Amount in millisatoshis (msats)
-- `description` - Invoice description
-- `description_hash` (optional) - Hash of the description
-- `expiry` (optional) - Expiry time in seconds
-
-Example:
-```
-nwcclient <connection URL> make_invoice 1000000 "Test invoice" "" 3600
-```
-
-#### pay_invoice
-
-```
-nwcclient <connection URL> pay_invoice <invoice> [amount]
-```
-
-- `invoice` - BOLT11 invoice
-- `amount` (optional) - Amount in millisatoshis (msats)
-
-Example:
-```
-nwcclient <connection URL> pay_invoice lnbc1...
-```
-
-#### pay_keysend
-
-```
-nwcclient <connection URL> pay_keysend <amount> <pubkey> [preimage]
-```
-
-- `amount` - Amount in millisatoshis (msats)
-- `pubkey` - Recipient's public key
-- `preimage` (optional) - Payment preimage
-
-Example:
-```
-nwcclient <connection URL> pay_keysend 1000000 03...
-```
-
-#### lookup_invoice
-
-```
-nwcclient <connection URL> lookup_invoice <payment_hash_or_invoice>
-```
-
-- `payment_hash_or_invoice` - Payment hash or BOLT11 invoice
-
-Example:
-```
-nwcclient <connection URL> lookup_invoice 3d...
-```
-
-#### list_transactions
-
-```
-nwcclient <connection URL> list_transactions [from <timestamp>] [until <timestamp>] [limit <count>] [offset <count>] [unpaid <true|false>] [type <incoming|outgoing>]
-```
-
-Parameters are specified as name-value pairs:
-
-- `from` - Start timestamp
-- `until` - End timestamp
-- `limit` - Maximum number of transactions to return
-- `offset` - Number of transactions to skip
-- `unpaid` - Whether to include unpaid transactions
-- `type` - Transaction type (incoming or outgoing)
-
-Example:
-```
-nwcclient <connection URL> list_transactions limit 10 type incoming
-```
-
-#### sign_message
-
-```
-nwcclient <connection URL> sign_message <message>
-```
-
-- `message` - Message to sign
-
-Example:
-```
-nwcclient <connection URL> sign_message "Hello, world!"
-```
-
-## Output
-
-The tool prints the JSON response from the wallet service to stdout. If an error occurs, an error message is printed to stderr.
-
-## Limitations
-
-- The tool only supports methods that have direct client methods in the nwc package.
-- Complex parameters like metadata are not supported.
-- The tool does not support interactive authentication or authorization.

-# Mock Wallet Service Examples
-
-This document contains example commands for testing the mock wallet service using the CLI client.
-
-## Starting the Mock Wallet Service
-
-To start the mock wallet service, run the following command from the project root:
-
-```bash
-go run cmd/walletcli/mock-wallet-service/main.go --relay ws://localhost:8080 --generate-key
-```
-
-This will generate a new wallet key and connect to a relay at ws://localhost:8080. The output will include the wallet's public key, which you'll need for connecting to it.
-
-Alternatively, you can provide your own wallet key:
-
-```bash
-go run cmd/walletcli/mock-wallet-service/main.go --relay ws://localhost:8080 --key YOUR_PRIVATE_KEY_HEX
-```
-
-## Connecting to the Mock Wallet Service
-
-To connect to the mock wallet service, you'll need to create a connection URL in the following format:
-
-```
-nostr+walletconnect://WALLET_PUBLIC_KEY?relay=ws://localhost:8080&secret=CLIENT_SECRET_KEY
-```
-
-Where:
-- `WALLET_PUBLIC_KEY` is the public key of the wallet service (printed when starting the service)
-- `CLIENT_SECRET_KEY` is a private key for the client (you can generate one using any nostr key generation tool)
-
-For example:
-
-```
-nostr+walletconnect://7e7e9c42a91bfef19fa929e5fda1b72e0ebc1a4c1141673e2794234d86addf4e?relay=ws://localhost:8080&secret=d5e4f0a6b2c8a9e7d1f3b5a8c2e4f6a8b0d2c4e6f8a0b2d4e6f8a0c2e4d6b8a0
-```
-
-## Example Commands
-
-Below are example commands for each method supported by the mock wallet service. Replace `CONNECTION_URL` with your actual connection URL.
-
-### Get Wallet Service Info
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" get_wallet_service_info
-```
-
-### Get Info
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" get_info
-```
-
-### Get Balance
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" get_balance
-```
-

-```
-
-This pays an invoice. You can use any valid Lightning invoice string.
-
-### Pay Keysend
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" pay_keysend "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef" 1000
-```
-
-This sends 1000 sats to the specified public key using keysend.
-
-### Lookup Invoice
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" lookup_invoice "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
-```
-
-This looks up an invoice by payment hash.
-
-### List Transactions
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" list_transactions 10
-```
-
-This lists up to 10 transactions.

-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" make_hold_invoice 1000 "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef" "Test hold invoice"
-```
-
-This creates a hold invoice for 1000 sats with the specified payment hash and description.
-
-### Settle Hold Invoice
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" settle_hold_invoice "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
-```
-
-This settles a hold invoice with the specified preimage.
-
-### Cancel Hold Invoice
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" cancel_hold_invoice "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
-```
-
-This cancels a hold invoice with the specified payment hash.
-
-### Sign Message
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" sign_message "Test message to sign"
-```
-
-This signs a message with the wallet's private key.
-
-### Create Connection
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" create_connection "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef" "Test Connection" "get_info,get_balance,make_invoice" "payment_received,payment_sent"
-```
-
-This creates a connection with the specified public key, name, methods, and notification types.
-
-### Subscribe
-
-```bash
-go run cmd/walletcli/main.go "CONNECTION_URL" subscribe
-```
-
-This subscribes to notifications from the wallet service.
-
-## Complete Example Workflow
-
-Here's a complete example workflow for testing the mock wallet service:
-
-1. Start the mock wallet service:
-   ```bash
-   go run cmd/walletcli/mock-wallet-service/main.go --relay ws://localhost:8080 --generate-key
-   ```
-
-2. Note the wallet's public key from the output.
-
-3. Generate a client secret key (or use an existing one).
-
-4. Create a connection URL:
-   ```
-   nostr+walletconnect://WALLET_PUBLIC_KEY?relay=ws://localhost:8080&secret=CLIENT_SECRET_KEY
-   ```
-
-5. Get wallet service info:
-   ```bash
-   go run cmd/walletcli/main.go "CONNECTION_URL" get_wallet_service_info
-   ```
-
-6. Get wallet info:
-   ```bash
-   go run cmd/walletcli/main.go "CONNECTION_URL" get_info
-   ```
-
-7. Get wallet balance:
-   ```bash
-   go run cmd/walletcli/main.go "CONNECTION_URL" get_balance
-   ```
-
-8. Create an invoice:
-   ```bash
-   go run cmd/walletcli/main.go "CONNECTION_URL" make_invoice 1000 "Test invoice"
-   ```
-
-9. Look up the invoice:
-   ```bash
-   go run cmd/walletcli/main.go "CONNECTION_URL" lookup_invoice "PAYMENT_HASH_FROM_INVOICE"
-   ```
-
-10. Subscribe to notifications:
-    ```bash
-    go run cmd/walletcli/main.go "CONNECTION_URL" subscribe
-    ```
-
-## Notes
-
-- The mock wallet service returns generic results for all methods, regardless of the input parameters.
-- The mock wallet service does not actually perform any real Lightning Network operations.
-- The mock wallet service does not persist any data between restarts.

+// Create client from NWC connection URI
+client, err := nwc.NewClient("nostr+walletconnect://...")
+if err != nil {
+    log.Fatal(err)
+}
+
+// Make requests
+var info map[string]any
+err = client.Request(ctx, "get_info", nil, &info)
+
+var balance map[string]any
+err = client.Request(ctx, "get_balance", nil, &balance)
+
+var invoice map[string]any
+params := map[string]any{"amount": 1000, "description": "test"}
+err = client.Request(ctx, "make_invoice", params, &invoice)
