“Escrow-backed” here describes x402 channel collateral and batching. It does not imply delivery acceptance, chargeback rights, dispute arbitration or custody by Agenstry.

Discovery-bias disclosure

Protocol shares describe Agenstry's indexed payment-labelled services, not global adoption. x402 is structurally easier to discover because it exposes multiple public catalogs and a live HTTP challenge; declaration-only rails are undercounted. Host identities also carry one primary label, while resource_protocols is the multi-rail endpoint view and can contain cross-source duplicate observations.

Measured

Gross inbound transfers of indexed USD-stable assets to a public recipient wallet, de-duplicated by network+wallet.

Not inferred

Wallet inflow is not automatically an x402/AP2/ACP sale. Signed receipts or payment identifiers are required for protocol-level attribution.
