How to Find Out When an NFT Was Minted

This tutorial explains the steps involved in getting the mint date of any given Ethereum Mainnet NFT.

Step 1. Use the events endpoint with the following details:

• protocol: ethereum

• network: mainnet

  https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/events
  

Step 2. Add the following parameters:

• contract address

  • parameter: contract_address
  • value: e.g. 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D

• token ID

  • parameter: token_id
  • value: e.g. 9999

• event type

  • parameter: event_type
  • value: mint

  https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/events?contract_address=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&token_id=9999&event_type=mint
  

Step 3. Execute the query.

For example, in cURL, you should run the following code:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/events?contract_address=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&token_id=9999&event_type=mint' -H 'Authorization: Bearer YOUR_API_KEY'

📘

Note!

To authorize your request, you need to get an API key and use it as a bearer token or a query parameter. Learn more: Authentication Guide

Step 4. Your results will look something like this:

{
    "data": [
        {
            "id": "2b3bbb3d-aa72-42a1-94c2-9e8f987a76fc",
            "contract_address": "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D",
            "token_id": "6853",
            "event_type": "transfer",
            "timestamp": "1655199885",
            "from_account": "0x5f6ac80CdB9E87f3Cfa6a90E5140B9a16A361d5C",
            "to_account": "0x70b97A0da65C15dfb0FFA02aEE6FA36e507C2762",
            "quantity": "1"
        },
        {...more events...}
    ],
    "meta": {
        "paging": {
            "next_page_token": "eyJ0aW1lc3RhbXAiOjE2NTUxNzY2NDcsInNpZCI6MTQ5ODU4MTU4fQ=="
        }
    }
}

The mint date is returned in Unix time by the timestamp field, e.g.:

• "timestamp": "1619858117"
