Example use cases
NFT trait verification before purchase
“Before I buy this NFT, can you pull the metadata for token ID 101 on the Berachain contract 0xabc123def456abc123def456abc123def456abc1 so I can check its rarity traits and attributes?”
NFT portfolio display enrichment
“I'm building a gallery of my Berachain NFTs — can you fetch the metadata for token ID 7 from contract 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef so I can show the image and description?”
Automated NFT collection audit
“I need to verify what's actually on-chain for our project — pull the metadata for token ID 500 from our Berachain contract at 0xfeed1234feed1234feed1234feed1234feed1234 and tell me what name, traits, and image URI are recorded.”

Endpoint
