99 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Look up any EVM chain by chain ID or name (8453, base, arbitrum): chain ID in decimal and hex, native currency, public RPC URLs, block explorers and testnet flag. Use to configure wallets, RPCs or cross-chain apps.
The transaction count of an account, which is the nonce its next transaction must carry. Ask for block "pending" to include transactions already in the mempool, which is what you want before signing; the default "latest"...
Read one 32-byte storage slot from a contract, the raw state under whatever the source code calls it. Returns the word as hex plus three readings of the same bytes - unsigned integer, address (low 20 bytes) and boolean -...

Is a Base address a smart contract or an EOA? Returns is_contract and bytecode size. Use when an agent must decide whether a recipient is a contract before sending funds or approving it.
ERC-20 total supply on Base, raw + formatted with decimals and symbol. Use when an agent needs a token's circulating-supply base for market-cap or dilution math.
Raw storage slot (eth_getStorageAt) of a Base contract. Use when an agent needs proxy implementation/admin slots or raw contract state.
