How this service works
ERC1155 multi-token balance for a wallet and token id on Base mainnet via balanceOf(address,uint256).
Output
Returns the integer quantity of the specified ERC-1155 token ID held by the given wallet address, as returned by the on-chain balanceOf(address,uint256) function on Base mainnet.
Example use cases
Gate access by token ownership
“Does wallet 0xDeF...456 hold at least 1 of token ID 3 from the ERC-1155 contract at 0xAbC...123 on Base? I want to know before letting them into the members-only channel.”
Game item inventory check
“How many of item token ID 99 does player wallet 0x111...aaa have in the ERC-1155 contract 0x222...bbb on Base mainnet? I need to know their sword count before they can enter the tournament.”
Audit ERC-1155 holdings
“Pull the balance of token ID 0 for wallet 0xFFF...000 from the ERC-1155 contract 0x333...ccc on Base — I'm auditing how many edition-one passes this address holds.”
Technical details
Endpoint
GEThttps://x402.agentindex.world/base/erc1155-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to read the ERC-1155 balance of a specific token ID for a wallet on Base mainnet specifically — especially for semi-fungible tokens (SFTs), gaming items, or multi-edition NFTs where one contract manages many token types. Prefer this over ERC-20 or ERC-721 balance endpoints when the contract follows the ERC-1155 standard with distinct token IDs.
Side effects
- Invalid wallet address format returns an error
- Invalid or non-existent token contract address returns an error or zero balance
- Token ID does not exist on the contract may return zero rather than an error
- Network congestion on Base may cause delayed or failed RPC reads
- Negative or non-integer token_id rejected by schema validation
