How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns NFT metadata for the specified opBNB token, typically including the token name, description, image URI, and an array of attributes/traits as defined by the smart contract's token URI standard (ERC-721/ERC-1155 metadata JSON).
Example use cases
NFT portfolio trait inspection
“I hold token ID 77 in the opBNB NFT collection at 0xDe...F01 — can you fetch its metadata so I can see all its traits and rarity attributes?”
Marketplace listing enrichment
“Before I list this opBNB NFT for sale, grab the on-chain metadata for contract 0xAa...B2 token ID 15 so I can fill in the name, image, and description fields automatically.”
NFT authenticity and details check
“Someone is trying to sell me an opBNB NFT — contract 0xCC...99, token ID 200. Can you fetch its metadata so I can verify the name, image, and properties actually match what they're claiming?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/opbnb/nft/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need NFT metadata specifically on the opBNB (optimistic BNB) Layer-2 network and want fast, pay-per-call access without managing your own RPC infrastructure. Prefer it over general-purpose blockchain RPC calls when you want a simple POST interface abstracting away the raw contract interaction, and over competing indexers when you only need individual token lookups rather than bulk collection queries.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Token ID does not exist on the contract (unminted or burned) returns a not-found error
- Contract does not implement a standard metadata URI function — metadata may be unavailable
- opBNB RPC node downtime or congestion may cause timeouts
- Malformed input (wrong address format) returns a validation error
- IPFS or off-chain metadata URI is unreachable, causing partial or null response
