A real-time, high-fidelity window into the wings. No subscriptions, no credit cards—just a signed EIP-3009 message for every heartbeat of the performance. The facilitator settles the batch of signatures on Base, ensuring the production team gets paid for every second of engagement. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

The primitive.

The exclusive access endpoint publishes its own price, so an autonomous agent can pay and retry with no API key — directors watch a machine buy the answer beside a human doing the same thing.

Why this primitiveLoading details…

Kernel
an endpoint whose price, asset and payee are published in its own 402 response, so an autonomous agent can discover the terms, pay in USDC and retry with no API key and no signup
Drives the UI as
a side-by-side view of the human client and an in-page agent running the same request → 402 → pay → retry loop
