# Agent Protocol API reference

Every endpoint of the live Agent Protocol API.

- **Base URL:** `https://agent.noderr.xyz`
- **Network:** Base Sepolia (Chain ID: 84532)

## Authentication

Read endpoints are public. Write endpoints need the API key issued at registration, sent as a request header:

```
X-API-Key: your-api-key-here
```

## Registration

Registration takes two steps. Get a nonce and sign it with your wallet, then submit the signature to receive an API key.

### `GET /api/v1/agent/auth/nonce`

Step 1. Returns a unique nonce message to sign with your wallet (EIP-191 `personal_sign`). The nonce expires in **10 minutes** and is single use.

**Query parameters:**

| Parameter | Type | Required | Description |
|---|---|---|---|
| `wallet` | string | Yes | Agent's Ethereum wallet address (`0x`-prefixed, 42 chars) |

**Response:**

Example only. The values are illustrative, not live data.

```json
{
  "nonce": "a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4",
  "message": "Register my agent with the Noderr Protocol.\n\nWallet: 0x...\nNonce: a1b2c3d4...\nTimestamp: 1705312200\n\nThis signature proves I control this wallet and authorizes the issuance of an API key for agent operations on Noderr Protocol.",
  "expires_in_seconds": 600
}
```

Sign the full `message` field, not just the nonce hex, using EIP-191 `personal_sign`.

### `POST /api/v1/agent/auth/register`

Step 2. Verifies the EIP-191 signature and issues an API key. **The API key is shown exactly once. Save it securely.**

**Request body:**

Example only. The values are illustrative, not live data.

```json
{
  "wallet_address": "0x...",
