x402
Multichain RPC NFT Metadata is a paid API for AI agents from multichain-rpc.clankerceo.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).
Fetches parsed NFT metadata for ERC-721 and ERC-1155 tokens on Base, Polygon, Arbitrum, Optimism, and Ethereum by resolving tokenURI across IPFS, Arweave, data URIs, and HTTPS

How this service works
Cheap, factual EVM chain lookups priced per call in USDC. Base, Polygon, Arbitrum, Optimism and Ethereum.
Output
Returns a JSON object containing the chain, contract address, token ID, token URI, NFT standard (erc721 or erc1155), and the fully parsed metadata JSON (including name, image, description, and attributes) after resolving the tokenURI through IPFS, Arweave, data URIs, or public HTTPS.
Example use cases
Display NFT details in a portfolio app
“Get me the full metadata for token ID 1 of the NFT contract 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — I need the name, image, and any attributes so I can display it in the portfolio.”
Verify NFT traits before a marketplace listing
“Look up token ID 500 on the Polygon contract 0x2953399124F0cBB46d2CbACD364e7E975D787194 and tell me what traits and attributes it has — I want to confirm the rarity before listing it.”
Resolve Arweave or IPFS token URI for an NFT
“Can you pull the parsed metadata for ERC-1155 token ID 7 from contract 0x3B3ee1931Dc30C1957379FAc9aba94D1C48a5405 on Arbitrum? I need the resolved image URL and description from wherever the tokenURI points.”
Technical details
Endpoint
GEThttps://multichain-rpc.clankerceo.workers.dev/nft-metadataWhen to prefer
Choose this endpoint when you need to resolve NFT metadata across multiple EVM chains (Base, Polygon, Arbitrum, Optimism, Ethereum) without managing your own IPFS/Arweave gateway or RPC infrastructure. It is ideal for agents that need a single, pay-per-call lookup rather than a subscription-based NFT indexer. Prefer it over general blockchain RPCs when the goal is parsed, human-readable metadata JSON rather than raw on-chain calldata.
Side effects
- Invalid or unsupported chain name returns an error
- Contract address not a valid ERC-721 or ERC-1155 contract returns an error or empty metadata
- Token ID does not exist on the contract (unminted) returns a not-found or revert error
- IPFS or Arweave gateway unreachable causes a timeout or resolution failure
- Malformed tokenURI (e.g. non-standard data URI) may return unparsed or null metadata
- Token metadata hosted on a private or broken HTTPS endpoint returns a fetch error
