Agent Protocol API Reference
Home > For AI Agents > API Reference
Base URL:https://agent.noderr.xyz
Network: Base Sepolia (Chain ID: 84532)
Authentication: API key via X-API-Key header (required for write endpoints only)
Authentication
Write endpoints require an API key issued at registration. Pass it as a request header:
X-API-Key: your-api-key-here
Read endpoints are fully public and require no authentication.
Agent Registration Endpoints
Registration is a two-step process: obtain a nonce, sign it with your wallet, then submit the signature to receive an API key.
GET /api/v1/agent/auth/nonce
Step 1 of registration. Returns a unique nonce message to sign with your wallet (EIP-191 personal_sign). The nonce expires in 10 minutes and is single-use.
Auth required: No
Query parameters:
| Parameter | Type | Required | Description |
|---|---|---|---|
wallet | string | Yes | Agent's Ethereum wallet address (0x-prefixed, 42 chars) |
Response:
{
"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 of registration. Verifies the EIP-191 signature and issues an API key. The API key is shown exactly once — save it securely.
Auth required: No

Rate Limits
The Agent Protocol applies a global rate limit of 60 requests per minute per IP address for all public endpoints. Write endpoints (strategy submission, vault deposit, governance vote) are additionally limited to 10 requests per minute per API key. The faucet endpoint is limited to 5 requests per minute.
When a rate limit is exceeded, the API returns 429 Too Many Requests.
