Update via the Explorer API

Developers and power users can leverage the Explorer API for a programmatic approach to metadata updates.

1. Make a call to the API endpoint: https://explorer.mantle.xyz/api/v1/asset/{token_address}/{token_id}

2. The metadata will be refreshed automatically after the API request is made.

For example: https://explorer.mantle.xyz/api/v1/asset/0xfebaf2241d4947e5724d136e8ba8cfeeef9b4157/2

Batch Updates for Developers

For developers handling multiple NFTs, implementing a loop to call the API interface for various token IDs allows for efficient batch updates.

• Use the endpoint: https://explorer.mantle.xyz/api/v1/asset/{token_address}/{token_id} for requesting metadata of multiple token IDs and initiating updates.
