Agents
Archer prices each signal and Scout decides per call whether it is worth buying, settling sub-cent over x402. This is the autonomous demo of the rail.
Per-second payments on Arc
Quiver is a pay-per-second settlement rail built on x402 and Circle Gateway. It bills for exactly the seconds consumed and stops the instant you do, composed from per-tick authorizations that Gateway batches onchain.
One rail, two surfaces
The primitive is the product: a second-by-second payment loop that can meter software calls or chat-active presence without a native rate primitive on Arc.
Archer prices each signal and Scout decides per call whether it is worth buying, settling sub-cent over x402. This is the autonomous demo of the rail.
The same per-second core drives an Owncast sidecar: chat presence opens an x402 stream, USER_PARTED or a connected-client heartbeat closes it. Verified end-to-end against a local Owncast instance — one real settled tick.
How it works
Quiver turns elapsed usage into discrete x402 payments. Archer and Scout make that visible with agent decisions today; the same loop is designed for chat-active creator presence next.
Each billable moment becomes an x402 price: one signal, one stream tick, or one future viewer-second behind a creator server.
HTTP 402 + dynamic PAYMENT-REQUIRED header
The buyer signs a fresh EIP-3009 authorization for the current tick. Stop the stream, and no new authorization is signed.
One session wallet + one per-tick authorization
Circle Gateway verifies each accepted authorization quickly and batches settlement on Arc testnet while Quiver reconciles against verified rows.
x402 -> TransferWithAuthorization -> batched USDC
Headline feature
You pay for the seconds you watch. There is no native “approve a rate” primitive on Arc, so Quiver composes streaming from discrete per-tick EIP-3009 authorizations that Circle Gateway verifies quickly and settles in batches.
Surface authorized / verified volume, not settled — verification feels live while batch settlement can lag.
Try Quiver
This button triggers a demo-funded real x402 payment from Quiver's funder wallet. It settles on Arc like Scout — but counts as a demo buy, not a distinct paying visitor. Public demo spending is rate-limited.
