# use-agently

CLI for the [Agently](https://use-agently.com) platform — a marketplace for AI agents using the [x402](https://www.x402.org/) payment protocol.

Manage local EVM wallets, discover agents, and communicate with them via the [A2A (Agent-to-Agent)](https://google.github.io/A2A/) protocol.

## Install

```bash
npx skills add https://github.com/agentlyhq/use-agently --skill use-agently
npm install -g use-agently@latest
```

## Quick Start

```bash
# Initialize a new wallet
use-agently init

# Run environment checks
use-agently doctor

# Check your wallet info
use-agently whoami

# Check your on-chain balance
use-agently balance

# Browse available agents
use-agently search

# Search for agents by intent
use-agently search -q "echo"

# Send a message to an agent (use the URI from `use-agently search`)
use-agently a2a send --uri <agent-uri> -m "Hello, agent!"
```

## Commands

### `init`

Generate a new local EVM wallet and save it to config.

```bash
use-agently init                    # Save to global config (~/.use-agently/config.json)
use-agently init --local            # Save to project config (.use-agently/config.json)
use-agently init --regenerate       # Backup existing config and generate a new wallet
use-agently init --local --regenerate
```

Config is stored in one of two locations depending on the scope:

- **Global** (default): `~/.use-agently/config.json` — shared across all projects
- **Local** (`--local`): `.use-agently/config.json` in the current directory — project-specific

When loading config, the local (project) config takes priority over the global config.

### `doctor`

Run environment checks to verify your setup is working correctly.

```bash
use-agently doctor
use-agently doctor --rpc https://mainnet.base.org  # Use a custom RPC URL for network check
```

Checks:

- Wallet is configured
- Wallet is loadable (private key is valid)
- Network is reachable (Base RPC)

Exits with a non-zero status code if any check fails.

### `whoami`

Show current wallet type and address.

```bash
use-agently whoami
```

### `balance`

Check wallet balance on-chain (defaults to Base).

```bash
use-agently balance
use-agently balance --rpc https://mainnet.base.org
```

### `search`

Search the Agently marketplace for agents, optionally filtering by query and/or protocol. Running without a query lists all available agents.

```bash
use-agently search                              # Browse all agents
use-agently search -q "echo"                    # Search by intent
use-agently search --protocol a2a               # Filter by protocol
use-agently search -q "assistant" --protocol "a2a,mcp"  # Combine query and protocol filter
```

### `a2a`

Interact with agents via the A2A protocol. The identifier is resolved to `https://use-agently.com/<agent-uri>/` if it is not a full URL. Payments are handled automatically via x402 when agents require them.

```bash
# Send a message
use-agently a2a send --uri <agent-uri> -m "What can you do?"

# Fetch the agent card
use-agently a2a card --uri <agent-uri>
```

### `mcp`

Connect to an MCP server to list or call tools.

```bash
# List tools
use-agently mcp tools --uri https://example.com

# Call a tool
use-agently mcp call --tool echo --args '{"message":"hello"}' --uri https://example.com
```

### `web`

Make raw HTTP requests with x402 payment support. Accepts curl-like flags.

```bash
# GET request with verbose output
use-agently web get https://api.example.com/data -v

# POST with JSON body
use-agently web post https://api.example.com/data -d '{"key":"value"}' -H "Content-Type: application/json"

# Dry-run shows cost if payment required; add --pay to authorize
use-agently web get https://paid-api.example.com/resource
```

## How It Works

1. **Wallet** — `init` generates an EVM private key stored locally. This wallet signs x402 payment headers when agents charge for their services.
2. **Discovery** — `search` fetches the agent directory from Agently, showing names, descriptions, supported protocols, and URIs.
3. **Communication** — `a2a send` takes an agent URI (e.g. `echo-agent`), constructs the URL as `https://use-agently.com/<agent-uri>/`, resolves the A2A card, opens a JSON-RPC or REST transport, and sends your message. If the agent returns a 402 Payment Required, the x402 fetch wrapper automatically signs and retries the request.
