The audio licensing endpoint publishes its own price, so an autonomous agent can pay and retry with no API key — videographers 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
