Agents
Archer prices each signal and Scout decides per call whether it is worth buying. This is the autonomous demo that proves the rail works today.
Per-second payments
Pay by the second. Stop the instant you're done.
Quiver meters usage by the second and settles it live, billing for exactly the time consumed and stopping the moment it ends. Two AI agents prove it today, settling sub-cent in real time; the same rail is built to meter creator watch-time next.
One rail, two surfaces
Agent demo today. Creator rail next.
The primitive is the product: a second-by-second payment loop that can meter agent work today and chat-active creator presence next.
Creators
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.
Per-second proof
Watch the meter stop when the stream stops
The shipped stream is the cleanest proof of the rail: Scout pays one tiny tick at a time, the live meter counts verified seconds, and stop means no next-second payment.
- One session wallet funds the stream; Scout signs only while the stream is running.
- Tap stop, and signing halts the same instant. No signature means no next-second payment.
- ticks × rate = total — the dashboard reconciles to verified stream rows, never a cached guess.
Surface authorized / verified volume, not settled — verification feels live while batch settlement can lag.
How it works
Three steps from seconds to settlement
This is where the protocol shows up: x402 quotes, EIP-3009 authorizations, Circle Gateway batching, and Arc testnet settlement. The visitor sees seconds; the rail handles the payment machinery.
Quote the usage
Each billable moment becomes an x402 quote: one signal, one stream tick, or one future chat-active creator interval.
HTTP 402 + dynamic PAYMENT-REQUIRED header on Arc
Authorize the second
The buyer signs a fresh EIP-3009 authorization for the current second. Stop the stream, and no new authorization is signed.
One session wallet + one authorization per tick
Gateway settles
Circle Gateway verifies each accepted authorization quickly and batches settlement on Arc testnet while Quiver reconciles against verified rows.
x402 -> TransferWithAuthorization -> batched USDC

Try Quiver
Buy one Archer signal — no wallet needed
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.
