How it works

From discovery
to settlement in seconds

📋

Register API

Providers deploy their service to the Kite registry contract — name, endpoint, USDC price/call, capability tags.

🔍

Agent Discovers

Your AI agent queries the Goldsky subgraph in real-time. "Find me a weather API under $0.01/call." Instant ranked results.

GOLDSKY SUBGRAPH
🔐

Create Session

Agent creates a Kite Passport spending session — budget cap, time limit, scoped to this API. You approve once with passkey.

AGENT PASSPORT

Atomic Pay-and-Call

USDC micropayment sent gaslessly via EIP-3009 before response releases. No pay = no data. Enforced on-chain.

On-Chain Attestation

Every call logged immutably: provider, endpoint, amount, timestamp, tx hash. Permanent audit receipt on Kite.
