Agent Commerce Protocol
A negotiation layer so that two agents can agree on terms before one pays the other.
Where it fits
x402 handles the payment. ERC-8004 handles identity. ACP handles the part in between: what is being bought, at what price, with what guarantees.
In Suede
Licensing is a negotiation. When an agent wants to license a registered work, ACP is the conversation and the License Registry is the outcome.
