Getting Started

Using JSON-RPC Requests to Access WebSockets

The tg_listen JSON-RPC method allows you to receive Spotter alerts.

To begin, use /genkey command in Spotter telegram bot.

Authenticate

Authentication for this API is done using an API key token. The API key token should be included in the endpoint URL using the key parameter.

wss://api.spotter.pessimistic.io/v1?key=API_KEY_TOKEN

Replace API_KEY_TOKEN with the actual API key token provided to you.
You can generate new API key in telegram bot by command /genkey

Subscribe to new alerts

Next, prepare to send WebSocket requests to the API. You can use command line tools like wscat or make requests from your project. Using wscat, you can send requests as follows:

create subscription request

{
  "jsonrpc": "2.0",
  "method": "tg_listen",
  "params": [],
  "id": 1
}

response

{
  "result": "0x44110d93799b5ab5",
  "id": 1
}

example of incoming alert

{
  "tx_hash": "0x35ad6c6f783c5327a52319f1cc8fc8eef0218d83adfa6bdbdda5367c1e0a6705",
  "risk_score": "high",
  "chain_id": "0x1",
  "subscribe": {
    "address": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",
    "chain_id": "0x1",
    "calls": ["0x06fdde03"],
    "funcs": [
      "0x095ea7b3",
      "0xd0e30db0"
    ]
  }
}

• "tx_hash" - transaction hash
• "chain_id" - transaction chain id
• "risk_score"-"medium"or"high"
• "subscribe" - Contract subscribe with which the alert interacts
• "address"
• "signatures"
• "calls"
• "funcs"
