Automatic Metadata Updates
For all collections that have metadata on IPFS we automatically refresh token metadata each time those tokens are requested on any NFT endpoint.
Each time a token is requested, it will be queued for metadata refresh.
Cool-off period​
Refreshing metadata is resource intensive - therefore we have a cool-off period during which the same token can’t be refreshed more than once.
If the token_uri points to IPFS - we allow refreshing every 10 minutes for each individual token.
