> Tanod chainpeek ERC-1155 Balance is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Returns the ERC-1155 token balance for a specific token ID held by a given address on Ethereum or Base.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tanod-chainpeek-erc-1155-balance-b55b3bd8 -d '<json body>'
```

Example prompt: Check how many of token ID 1 from the ERC-1155 contract 0x495f947276749Ce646f68AC8c248420045cb7b5e are held by wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum.

## When to prefer this

Choose this endpoint when you need to query ERC-1155 multi-token balances (not ERC-20 or ERC-721) on Ethereum or Base without setting up your own RPC infrastructure. It is ideal for agents that need a pay-per-call, no-signup solution for on-chain balance lookups, especially for gaming tokens, digital collectibles, or access-gating logic involving multi-token standards.

## Known failure modes

- Invalid address format (not matching 0x + 40 hex chars) returns a validation error
- Token ID out of range or malformed returns a parse error
- Unsupported chain (not ethereum or base) returns an enum validation error
- Contract address is not an ERC-1155 contract — is_erc1155 may be false or call may fail
- RPC node timeout or network congestion causing delayed or failed response
- Token ID does not exist on the contract — balance returned as 0

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object with the block number at which the query was made, the chain name, the holder's address, the ERC-1155 contract address, the queried token ID, the token balance as a string, and a boolean confirming the contract is ERC-1155.
