chain_1155_balance

ERC-1155 balance of one id

balanceOf(account, id) for a multi-token contract, formatted with whatever supply unit the contract uses — the read a Zora/Sudoswap-style position tracker needs, which an ERC-20 or ERC-721 lookup cannot answer. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche.

The same decoded header /chain/block gives, addressed by hash instead of height — which is what a receipt, a log or a reorg report actually hands you. Costs $0.001 USDC per call.

chain_block_by_timestamp

Which block was mined at a time

Binary-searches the header timestamps for the first block at or after a unix time — every 'what was the supply / who held what on that date' question starts here, and no public node offers the lookup.

Scans deployed bytecode for 4-byte selectors we can name from a derived table: what this contract can be asked to do, read off the code rather than trusted from a README. Costs $0.001 USDC per call. Chains: base, ethereum, arbitrum, bsc, polygon, optimism, avalanche. Byte-identical to GET /chain/bytecode-capabilities?chain=base&address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&count=8.

chain_bytecode_fingerprint

Fingerprint a contract's code

SHA-256 of the deployed bytecode plus its size and edges — two addresses with the same fingerprint are the same compiled contract, which is how a clone of a known scam shows up before you interact with it.

chain_contract_diff

Same contract, two addresses?

chain_logs

Event logs for an address or topic

eth_getLogs over a bounded window (max 1000 blocks) with an address and/or first topic — transfers and events without running an indexer. Refuses an unfiltered scan.

Up to 10 contract reads, one payment

Batched eth_call: ten (target, calldata) pairs settled once, each answered independently so one reverting view cannot fail the rest. A tenth of the per-call cost of doing them one at a time.

getApproved(tokenId) — the single-operator approval on one id. Non-zero means someone other than the owner can transfer that exact token without owning it. Costs $0.001 USDC per call.
