InkStream · Agent Pay

A metered narrative engine where every paragraph is a micro-transaction. Readers pay-per-scroll to reveal the next beat of a story, while authors receive instant EIP-3009 settlements. No subscriptions, no ads, just pure narrative liquidity. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

The primitive.

full primer →

The short story writing endpoint publishes its own price, so an autonomous agent can pay and retry with no API key — writers 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
