METASTROFE · Agent Pay

METASTROFE is a living manuscript where each stanza is locked behind a micro-transaction. Paying the toll doesn't just grant access; it triggers a smart contract mutation that evolves the vocabulary and tone of the poem for the next reader based on the previous payer's wallet activity. A collaborative, permanent descent into a collective narrative where reading is an act of creation. 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 dynamic poetry 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

writer credentials

CanonInk · Agent Pay

Each successful peer-review or automated narrative audit mints a tradeable, liquid credential. Payment isn't just a fee; it's the 'skin in the game' required to trigger the verification oracle and filter out low-effort noise in the creator economy.

GHOSTWRITER · Agent Pay
