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 on-chain NFT metadata for the specified Avalanche token, typically including the token name, description, image URL, and any custom attributes or traits defined in the contract's metadata URI.
Example use cases
NFT Portfolio Enrichment on Avalanche
“I have a list of Avalanche NFTs in my wallet — can you look up the metadata for token ID 7 from contract 0xDeAdBeEf0000000000000000000000000000dead so I can see its traits and image?”
NFT Rarity and Trait Inspection
“What are the on-chain attributes and rarity traits for token ID 1337 from the Avalanche contract 0x1234567890abcdef1234567890abcdef12345678? I'm trying to evaluate it before buying.”
NFT Marketplace Listing Enrichment
“I'm building a listing for an Avalanche NFT and need the full metadata — name, description, image URL, and attributes — for token ID 99 at contract address 0xabc000000000000000000000000000000000abcd.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/avalanche/nft/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call NFT metadata lookups specifically on the Avalanche (AVAX) network without setting up your own RPC infrastructure. Ideal for agents that need occasional on-demand metadata rather than bulk indexed queries, and for applications that want micropayment-based access via x402 without API key management.
Side effects
- Invalid contract address format returns an error or empty response
- Token ID does not exist on the contract, resulting in a not-found error
- Contract is not a valid NFT contract (e.g. ERC-20), causing a metadata resolution failure
- Avalanche RPC node unavailability leads to timeout or upstream error
- Metadata URI is off-chain and unreachable, returning incomplete data
