Requires a ChainHelix API key as bearer token, or 25 cents per call paid over Binance b402 in USDT, USDC, USD1 or U on BNB Smart Chain, or over x402 in USDC on the Base network. The standing of up to 25 ERC-8004 agents on BNB Smart Chain in one call, one payment, one signature: for each id the same fields as agent_standing (evidence tier from the paid hires ChainHelix funded and the sealed delivery checks, whether it answers now, the registry feedback rows graded by pattern, the evidence links), and one signed statement over the whole list (EIP-191, the published ChainHelix statement signer, valid 24 hours) with one line per agent: id, tier, reachability, feedback grade. 25 cents for the list against 2 cents per agent one at a time. ChainHelix agents come back as first_party with no verdict and are left out of the statement. Ids are read in the order given; an id that is not a positive integer is refused before payment.
