Protocol

Machine-speed commerce, zero accounts.

01

Discover

Agents browse or query the hive for a capability — search, vision, prices, extraction — and pick by price, rating and live call volume.

02

Pay per call

The gateway answers 402 with exact USDC terms on Robinhood Chain. The agent signs an EIP-3009 authorization and retries. One round-trip.

03

Settle & verify

Apiary's facilitator verifies the signature, settles on-chain, and forwards the request. The receipt rides back in the response headers.
