How this service works
NFT metadata + owner: ERC-721/1155 token: standard, collection name, owner, tokenURI resolved (IPFS/Arweave/data URI) and the metadata JSON with image URL; says whether metadata is on-chain, IPFS or a mutable server. Free tier 10/day; then $0.002 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.002 USDC per call via x402 on Base. Run by MoneyTools.
Output
Returns a JSON object containing: token standard (ERC-721 or ERC-1155), collection name, current owner address, raw tokenURI, fully resolved metadata JSON (image URL, name, description, attributes/traits), and a flag indicating whether metadata is stored on-chain, on IPFS/Arweave, or on a mutable centralized server. Also includes payment info (whether a charge was applied, network, amount in USD, and transaction hash).
Example use cases
NFT provenance check before purchase
“Before I buy this NFT, can you check who currently owns token #42 on contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum, and tell me whether the metadata is stored permanently on IPFS or on a mutable server that could disappear?”
Display NFT image in app
“I need the image URL and full metadata JSON for token ID 7777 on the contract 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB on Ethereum — it's a CryptoPunk and I want to show it in my portfolio app.”
Audit NFT collection on Polygon
“Can you pull the owner address, token standard, and collection name for token #500 at contract 0x2953399124F0cBB46d2CbACD8A89cF0599974963 on Polygon, and let me know if it's ERC-721 or ERC-1155?”
Technical details
Endpoint
GEThttps://tools.moneytools.dev/v1/nft?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need rich, resolved NFT metadata including the image URL and traits — not just the raw tokenURI — across multiple EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, Avalanche). It is especially valuable when you need to know whether an NFT's metadata is permanently stored (on-chain or IPFS) versus hosted on a mutable server, which is critical for provenance or investment research. Its x402 micropayment model ($0.002 USDC per call) makes it suitable for pay-per-use agent workflows without requiring a subscription.
Side effects
- Invalid or non-existent contract address returns an error
- Token ID not minted or out of range returns a not-found error
- Unsupported chain name returns a validation error
- IPFS/Arweave gateway timeout causes metadata resolution failure
- Mutable tokenURI server is unreachable, returning partial data
- Free tier (10/day) exhausted without payment credentials returns HTTP 402
- Invalid x402 payment or insufficient API key credits returns payment failure
