How this service works
Use when you need how many copies of an ERC-1155 token id an address holds on Base, Ethereum, Arbitrum, Optimism or Polygon, via balanceOf(account, id). Read-only public data.
Output
Returns the integer count of how many copies of the specified ERC-1155 token ID the given address holds in the given contract on the selected chain, equivalent to calling balanceOf(account, id) on-chain.
Example use cases
NFT edition ownership verification
“Check how many copies of ERC-1155 token ID 1 the wallet 0x1111111111111111111111111111111111111111 owns on contract 0x2222222222222222222222222222222222222222 on Ethereum — I want to know if they qualify for a multi-copy holder reward.”
Game item inventory lookup
“How many of game item token ID 99 does player wallet 0xAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA hold in the contract 0xBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB on Polygon? I need the count to calculate their in-game crafting resources.”
Cross-chain token balance comparison
“Tell me how many copies of ERC-1155 token ID 3 wallet 0xCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC holds in contract 0xDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD on Arbitrum — I'm auditing balances across chains.”
Technical details
Endpoint
GEThttps://biosfera.46-62-215-147.sslip.io/o/erc1155-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need the balance of an ERC-1155 (multi-token standard) token — where a single address can hold multiple copies of the same token ID. Use this instead of ERC-721 ownership endpoints (which only track single NFT ownership) or ERC-20 balance endpoints. Ideal for semi-fungible tokens like game items, event tickets, or edition-based NFTs where quantity per wallet matters.
Side effects
- Invalid Ethereum address format (must match 0x followed by 40 hex chars) returns a validation error
- Unsupported chain value returns an enum validation error
- Token ID out of range or non-numeric returns a validation error
- Contract address does not implement ERC-1155 may return zero or an error
- Network timeout or RPC node unavailability returns a service error
- Missing required query parameters returns a 400-level error
