Validate an asset

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.

https://api.opensea.io/asset/<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.
