This endpoint is used to check the metadata URL on a given NFT.

If you're having issues getting your items to show up properly on OpenSea (perhaps they're missing an image or attributes), you can debug your metadata using the /validate API endpoint.<your_contract_address>/<your_token_id>/validate/

Simply hit the URL with your contract address and token ID to see if there are any errors with your metadata URL.


Requests to this endpoint require an API key. If you don't have an API key, please request one.

The endpoint will return the following fields:

Returns link with metadata information


Displays any errors the metadata URL has
