Here is an article on how to obtain the first Mint transaction through the address of Token using an application with the Helius API and extract the Development Directorate:
Title: Obtaining the first Mint transaction by Token direction with Helius API
Introduction:
Helius is a popular decentralized finance platform that allows developers to create, manage and exchange tokens in blockchain. In this article, we will explore how to obtain the first mint transaction through the direction of Token using the Helius API and we will extract the Development Directorate.
Obtaining Mint’s first transaction:
To recover the first mint transaction using Token’s address, you must use the final point Get/Tokens/{Tokenaddress}/Minting with a request body of ‘Requirements’. Here is an example of how to do it:
`Bash
Curl -x Get \
Whew/minting \
-H 'Authorization: Bearer your_api_key' \
-H 'Type of content: application/json'
Replace{tokenaddress}with the direction of Token for which you want to recover mint transactions.
Application body:
The application body must contain a list of mint events in JSON format. Events include the following information:
- ID
: Unique identifier for the event
- Address’: Token address
Type: Type of event (for example," mint "," transfer ")
- Date: Data associated with the event
Here is an example request body:
`JSON
[
{
"ID": 1,
"Address": "0xtokenaddress",
"Type": "mint",
"Date": {
"Quantity": 1000,
"Currency": "eth"
}
},
{
"ID": 2,
"Address": "0xothertokenaddress",
"Type": "transfer",
"Date": {
"From": "0xanothertokokenaddress",
"To": "0xthirdokenaddress",
"Quantity": 500
}
}
]
Extraction of the Development Directorate:
To extract the diversion from the Token address, you can use the final point 'Getasset to obtain asset metadata for the token.
`Bash
Curl -x Get \
\
-H 'Authorization: Bearer your_api_key' \
-H 'Type of content: application/json'
The answer must include an active object with the following information:
- Address
: Token's address
- Retadss
: the direction of DEV (or" 0xDevaddress "if it is not found)
Then you can extract the Development Directorate of this answer.
Extraction of the Response of the Development Directorate:
JSON
{
"asset": {
"Address": "0xtokenaddress",
"Retdress": ""
}
}
The 'Retdress field is empty in the previous example, but it is possible to verify the specific structure of its response.
Putting everything together:
To obtain the first mint transaction by Token direction and extract the detour, follow these steps:
- Obtain the first mint event using Helius’s API.
- Remove the data associated with the event.
- Use the final point
GTASSETto obtain asset metadata for the token.
- Remove the field ‘return’ from the answer.
Here is a fragment of example code in Python:
“ Python
Import requests
Def get_first_mint_transaction (Token_address):
Obtain the first mint event using Helius API
URL = “
ANSWER = REQUESTS.get (URL, headed = {‘Authorization’: ‘Carrier your_api_key’})
Events = Answer.json () [‘events’]
Extract the data associated with the event
Data = Next (event [‘data’ for events)
Obtain asset metadata using Getset Endpoint
URL = “
ANSWER = REQUESTS.get (URL, headed = {‘Authorization’: ‘Carrier your_api_key’})
Assets = Answer.
