x402
NFT Metadata – tokenURI / uri Lookup is a paid API for AI agents from scanpay-edge.alextaghiashvili.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-01).
Fetches ERC-721 or ERC-1155 NFT metadata (tokenURI/uri, collection name, and symbol) for a given token ID via eth_call on Base or Ethereum.

How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
Returns the tokenURI (for ERC-721) or uri (for ERC-1155) exactly as stored on-chain, plus the collection's name and symbol retrieved via eth_call — all for the specified contract address, token ID, and chain (Base or Ethereum).
Example use cases
Resolve NFT image for display
“What is the metadata URI for token ID 7777 of the contract 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB on Ethereum? I want to know what image it points to.”
Verify NFT collection name and symbol
“Can you confirm the collection name and symbol for the NFT contract 0x2953399124F0cBB46d2CbACD8A89cF0599974963 on Base? I need to make sure it's the right project before listing it.”
Enrich NFT portfolio with metadata
“For each of these NFTs I hold, fetch the tokenURI and collection name — token ID 5 from contract 0x60E4d786628Fea6478F785A6d7e704777c86a7c6 on Ethereum and token ID 12 from 0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401 on Ethereum.”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/nft-metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain tokenURI/uri and collection name/symbol for a specific ERC-721 or ERC-1155 token on Base or Ethereum without setting up your own RPC node or indexer. It is ideal for lightweight, per-token metadata resolution where you don't need full indexing or historical data. Prefer this over general-purpose blockchain RPC endpoints when you want a single paid, low-latency call that bundles tokenURI and collection info together.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Token ID does not exist on the contract — may return empty/zero tokenURI
- Contract does not implement ERC-721 or ERC-1155 — eth_call may revert or return unexpected data
- Unsupported chain specified — only Base and Ethereum are supported
- Network or RPC timeout on the underlying eth_call
- Payment not processed (x402 payment required at $0.01 USDC per call)
