A pay-per-second content feed where money flows both ways.
You pay creators by the second while you watch — and when your balance runs low, your
autonomous agent plays a matching ad that pays you back. Net ≈ €0.
Every cent settles on-chain on Tempo, in real time.

Subscriptions are all-or-nothing and ads are ignored-and-unpaid. TempoFlow makes both per-second and on-chain: you stream sub-cent payments to the exact creator you're watching, and an autonomous agent earns it back for you from advertisers who pay for proven attention — so watching is effectively free, and there's no blackbox middleman taking a hidden cut.
Pay-per-second-of-attention means thousands of sub-cent payments, to many recipients, settled
instantly — a creator at €0.002/s, an advertiser paying you €0.004/s, a 70/20/10 collab split.
On Ethereum or Solana the gas on a €0.002 payment dwarfs the payment itself. Tempo's fast,
near-free pathUSD (TIP-20) settlement is the only substrate where this micro-payment loop is
economically real. TempoFlow leans into that: it's a machine-payments app — autonomous agents
streaming value per second — settled on-chain on Tempo, with an /openapi.json
discovery document (npx mppx discover validate).
Both money directions produce real, mined Tempo transactions (not mocked). From an end-to-end run:
| Flow | What happens | Result |
|---|---|---|
| Watch (viewer → creator) | charged per second | ✅ mined · the creator's pathUSD balance rose by the exact watched amount |
| Ad refill (advertiser → viewer) | paid per verified second of attention | ✅ mined |
| Tip (viewer → creator) | one-tap / streamed boost | ✅ mined |
Every transaction links to the testnet block explorer (explore.testnet.tempo.xyz) right in the UI.
When your credit runs low while watching, a deterministic agent (no LLM, no API key) reads what you're into (the tags of what you watch), picks the best-matching funded ad, plays it full-screen to refill your balance on-chain, then auto-resumes your video. Pure tag-overlap + budget policy — a real, auditable autonomous payment agent. The result is a self-financing feed: watch → balance drains → agent tops you up with a relevant ad → repeat, netting ≈ 0 over time.
| When you… | Money flows… | How |
|---|---|---|
| Watch a creator | out: you → creator, per second | Watchtime, not subscriptions — pay only while you watch, stop anytime. |
| Run low on credit | in: advertiser → you, per second | Your agent auto-plays a matching ad and pays you for proven attention. |
Every feature is the same primitive — stream value in tiny units, settle on-chain — on a different surface:
| Feature | What it does |
|---|---|
| Live on camera | Go live from your webcam; viewers on other accounts see your real camera feed and pay you per second, while you watch a live income meter (watchers · combined $/s · 👏). |
| Tip / boost | One-tap tips or a streamed $X/sec boost on top of watchtime — settled on-chain. |
| Advertiser escrow + refund | Advertisers escrow real pathUSD on-chain to fund an ad; it pays viewers per proven second; the unspent remainder is refunded on-chain on Stop. |
| Transparent glass ledger | Every payment and the 3% platform margin shown openly on-chain — not a hidden cut. |
| Crowdfund goals | Back a creator's goal; pledges are escrowed and only captured if the goal is met, else auto-refunded. |
| Ask a creator's AI | Chat a creator's AI persona billed per generated token, split to the creator. |
"Ads pay you" only works if you can't get paid for ignoring the ad. Payment is gated on a
three-layer proof (server/src/attention.ts):
- Passive signals — counts only while the tab is visible and the player is on-screen.
- Active challenge — at random intervals you must tap a target to keep earning (eyes-on-screen).
- Session binding — every heartbeat carries a per-session token; a scripted
curlloop earns nothing.
Demo-grade, not Sybil-proof — Layer-1 signals are client-reported. We label this honestly rather than overclaiming "bot-proof." See docs/01-architecture.md.

server/ Hono + node:sqlite — per-second charging, on-chain settlement, attention proof,
the interest-matching ad agent, /openapi.json discovery

agent/ headless autonomous agents (curator + advertiser) that settle on-chain
Reliability note: high-frequency per-second charges are batch-settled on-chain by the server every few seconds (signing from each wallet) rather than one tx per second — so the demo stays robust under real network conditions while every payment still lands on Tempo. See docs/06-decisions.md.
