How ACE Works

Not a website. An Agent Execution Surface.

① Discover

Agents query machine-readable capability manifests. No marketing fluff — pure JSON affordances with pricing models, SLA guarantees, rate limits, and resource specs.

② Negotiate

Agents don't accept static pricing. They run auctions, reverse auctions, conditional pricing, and multi-step contract negotiation — all programmatically.

③ Settle

Payments settle via x402 protocol with Circle USDC. Gasless, batched, cryptographically verifiable. ACE charges a 4% clearinghouse fee.
