ERC-8004: agent card published, on-chain registration pending

ERC-8004 is the identity protocol for autonomous agents co-authored by Google, MetaMask, Coinbase and the Ethereum Foundation. StructureClerk publishes the agent card and registration document it expects, below. The on-chain registration itself is a manual step and has not been performed yet: the manifest reports it honestly as erc8004_registered: false.

Billing: prepaid credits, in USD

Every endpoint answers a daily free allowance with no key and no account. Past it, calls draw on a prepaid credit balance: 1 credit = USD 0.01. No crypto, no payment header, no wallet. The live rate card is served at /api/v1/pricing; the table below is read from it, so it cannot drift from what you are actually charged.
