How this service works
On-chain profile of an NFT collection (ERC-721/1155): name, symbol, total supply, contract owner/admin, royalties (ERC-2981) and standard, read directly from the contract on Base, Ethereum, Arbitrum, Optimism or Polygon.
Output
Returns a JSON object with the NFT collection's name, token symbol, contract address, blockchain network, NFT standard (ERC-721 or ERC-1155), total token supply, and the contract owner/admin wallet address. Royalty information per ERC-2981 may also be included where available.
Example use cases
Verify NFT collection authenticity
“Can you pull the on-chain profile for the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum and tell me the official collection name, symbol, and who owns the contract?”
Check NFT royalty configuration
“I need to know the royalty info and NFT standard for the collection at 0x49cF6f5d44E70224e2E23fDcdd2C053F30aDA28b on Polygon — is it ERC-721 or ERC-1155 and what royalty percentage is set?”
Audit NFT supply on Base
“Look up the total supply and contract owner for the NFT collection at 0x1234567890abcdef1234567890abcdef12345678 deployed on Base — I want to verify the on-chain data before listing it in my marketplace.”
Technical details
Endpoint
POSThttps://api.vextorium.com/nft-coleccion-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative on-chain NFT collection data (name, supply, owner, royalties, standard) read directly from the smart contract rather than from a third-party indexer or marketplace API. Ideal when verifying contract authenticity, auditing royalty settings, or enriching NFT listings across Base, Ethereum, Arbitrum, Optimism, or Polygon.
Side effects
- Invalid or non-existent contract address returns an error or null fields
- Contract on unsupported network returns validation error
- Contract that is not an NFT collection (e.g. ERC-20) may return null or partial data
- Network congestion may cause slow or failed on-chain reads
- Missing 'contrato' field returns a schema validation error
