Example use cases
Check NFT traits before bidding
“Before I bid on this NFT, can you fetch the metadata for token #7495 at contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum? I want to see the attributes and rarity traits.”
Display NFT in a portfolio app
“I need the image URL, name, and description for token #42 at contract 0xd8a90ef2b7e6b9d82a65a6d4b9a2d5e8f1c3b7a9 on Base so I can display it in my NFT portfolio.”
Verify NFT collection details
“Can you look up the collection name and token URI for token #1 in the contract 0xCB133Ad04DCE012B27D0e3b3e9e5E7f9A2c4D6F8 on Ethereum? I want to confirm it's part of the right collection.”
Technical details
Endpoint
GEThttps://klymax402.com/api/nft-metadata/api/metadataWhen to prefer
Use this endpoint when you need structured NFT metadata (image, traits, description, collection name) for a specific token on Ethereum or Base without managing your own RPC infrastructure or API keys. It is well-suited for agents that need to display, analyze, or verify individual NFT tokens on a per-call basis at low cost via x402 USDC micropayments.
Side effects
- Invalid or non-existent contract address returns empty or error response
- Token ID not found within the contract returns null metadata
- Unsupported chain value (not 'ethereum' or 'base') may result in an error
- Payment failure (insufficient USDC) returns 402 Payment Required
- Rate limiting or upstream RPC issues may cause timeouts
- Contracts that store metadata off-chain or on IPFS may return incomplete data if the URI is unavailable
