4. Debugging your metadata

Using the /validate endpoint

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 following API endpoint.

https://testnets-api.opensea.io/asset/<your_contract_address>/<your_token_id>/validate/ 

or

curl --request GET \
     --url https://api.opensea.io/api/v1/asset/0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d/1/validate \
     --header 'Accept: application/json' \
     --header 'X-API-KEY: 4d51f7fa929e4880a17a98d8c97e57b5'
