Public data

Look up public blockchain data.

Your AI can look up public accounts, assets and transactions through the iKnow Blockchain connection: today for 14 of the 151 chains; lookups for the rest are not built yet. The website itself does not run lookups; it shows what each chain supports and its limits.

What the answers mean

Available: The connection can read this from a named public provider. One address or transaction at a time; never a complete wallet.
Needs a provider key on our server: The read depends on a provider that needs a key. Without one, the answer says so and returns no figures.
Not applicable on this network: This kind of record does not exist on the network, or the network keeps it private by design; the row says which. It is never reported as zero.
Not available yet: iKnow Blockchain has not built this lookup for the chain. That is a limit of the service, not a statement about the network.
Temporarily unavailable: When a provider fails during a lookup, the answer says the source is unavailable and gives the last successful result only if one is known.

These statuses come from the coverage description of the prepared release (version 0.6.0-rc.1); the live connection still runs version 0.5.0-rc.1. They describe what is built, not live provider health.

Chains with lookups (14)

Arbitrum One ARB

Networks: mainnet

Public-data lookups for Arbitrum One
Lookup	Status	What it covers and its limits
Address or account	Available	native ETH balance, transaction count and code presence at provider-reported latest state Native-only operation; use separate indexed asset and NFT operations.
Tokens and assets	Available	paginated Blockscout-indexed ERC-20 and aggregate ERC-721/ERC-1155 balance rows Best-effort and incomplete; aggregate rows are not token-instance evidence.
NFTs	Available	paginated Blockscout-indexed ERC-721/ERC-1155 token IDs and exact quantities Best-effort and incomplete; embedded/offchain metadata is omitted.
Transactions	Available	transaction and receipt execution from the fixed public RPC No independent Ethereum settlement, trace or intent verification.

Avalanche AVAX

Networks: c-chain-mainnet

Public-data lookups for Avalanche
Lookup	Status	What it covers and its limits
Address or account	Available	native AVAX balance, nonce and code presence at provider-reported latest state No identity, control, history or P/X-Chain state; use asset operations for indexed tokens.
Tokens and assets	Available	paginated Ava Labs Data API ERC-20 balances with exact base units and native context Indexer-dependent and incomplete; anonymous access has lower rate limits. Zero/spam/nonstandard/unindexed balances can be misleading or absent.
NFTs	Available	separately paginated ERC-721 and ERC-1155 token-ID evidence with exact ERC-1155 balances ERC-721 quantity is unavailable and never inferred as one. Separate standard pages are non-atomic and indexer-dependent.

Base ETH

Networks: mainnet

Public-data lookups for Base
Lookup	Status	What it covers and its limits

Tokens and assets	Available	paginated indexed token balances through anonymous Base Blockscout or explicitly injected Alchemy, with exact contract base units Best-effort provider index; incomplete and not a portfolio or ownership guarantee.
NFTs	Available	paginated ERC-721/ERC-1155 token IDs with exact quantities through anonymous Base Blockscout or explicitly injected Alchemy Indexer-dependent instances only; no ERC-404 or offchain metadata/media.

Public-data lookups for Cardano
Lookup	Status	What it covers and its limits
Address or account	Available	one validated mainnet payment address and its indexed lovelace balance Not a whole-wallet or stake-account balance.
Tokens and assets	Available	bounded paginated Koios native-asset rows for one payment address Aggregate inventory remains unclassified; a separate bounded operation reports only standards-signaled NFT evidence.

Each of these chains has a full profile, reviewed developments and topics your AI can explain. Public-data lookups for them are not built yet.

Try a lookup in your AI

After you connect, ask for one public address or transaction on a chain marked available, and say which network. Then open the cited provider link. A provider error or a private value stays unknown in the answer, never zero.
