Replace <your_token> with your actual JWT token and use valid Solana transaction signatures.

Use Cases

Verify Specific Transactions

Use this endpoint to retrieve detailed information about specific trades when you have their transaction signatures. This is useful for:

Verifying trade execution
Building transaction history views
Reconciling on-chain data with platform data
Investigating specific trades

Batch Trade Lookup

Retrieve multiple trades in a single request by providing an array of signatures:

import requests

# Get multiple trades at once
signatures_to_check = [
    "sig1...",
    "sig2...",
    "sig3...",
    "sig4...",
    "sig5..."
]

url = "https://frontend-api-v3.pump.fun/trades/signatures"
headers = {
    "Authorization": "Bearer <your_token>",
    "Accept": "application/json",
    "Content-Type": "application/json"
}

response = requests.post(url, headers=headers, json={"signatures": signatures_to_check})
trades = response.json()

for trade in trades:
    print(f"Trade {trade['signature']}: {trade['amount']} {trade['tradeDirection']}")
