Live, simulated demonstration
AssetRouter keeps human reading intact while publishers price selected machine access. Toggle between x402 — where an AI agent pays the exact price per call in USDC (a stablecoin pegged 1:1 to the dollar) — and prepaid credits, where a human tops up a balance with a card (minimum €5) and then spends it. See why cards force you to prepay, and what that costs.
Choose a payment method and an asset, then run the payment. Each step is the real protocol exchange.

Five steps, fully machine-to-machine.
The same asset, paid two ways — the difference is the whole thesis.
A card's fixed fee (≈ 2.9% + €0.30) makes a 5-cent charge impossible. So you prepay credits (minimum €5) and draw them down. x402 simply pays the exact €0.05 per call.
USDC on Solana clears in under a second. A card top-up settles in ~2 business days, and your money sits as prepaid float until you spend it.
When credits run dry, a human must add more (min €5). An agent with x402 keeps paying on its own, within its delegated budget.
Every purchase carries rights, C2PA provenance, and a settlement receipt — proof of who paid for what, and how it may be used.
| For the same asset | 💳 Prepaid credits (card) | 🤖 x402 — Agentic |
|---|---|---|
| Who pays | A human tops up, then spends | The agent, per call |
| Smallest real spend | Prepay ≥ €5, then any size | Exactly €0.05, no minimum |
| Card / network fee | ≈ 2.9% + €0.30 per top-up | ≈ $0.0001 per call |
| Settlement | Top-up T+2, then prepaid | Under 1 second |
| Float / lock-in | Yes — money sits as credits | None — pay as you go |
| Works machine-to-machine | No (human top-up) | Yes, natively |
