The token-balance read wallet-tracking, copy-trade, treasury and trading agents poll constantly — the most-called RPC read after native balance. Live public RPC; undercuts onesource at $0.001.

Pre-trade safety check for any token contract: is it a honeypot, buy/sell tax, mintable, owner can reclaim, transfer-pausable, blacklist, open-source, holder count — plus a DANGER/HIGH_RISK/CAUTION/OK verdict and risk flags. The call every trading and sniping agent should make BEFORE buying. Live from GoPlus Security across Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche.

Look up any transaction by hash: confirmation status (success/failed/pending), block number, confirmations, value, from/to, fee paid, gas used, and the decoded method. The read every settlement, trading, and payment agent polls after sending a tx to confirm it landed. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free upstream (Blockscout); one paid call instead of running your own RPC.
