Cheap L2 fees are the economic precondition x402 keeps citing

Coinbase’s x402 launch note argued that cent-level L2 fees revive HTTP micropayments.

The x402 announcement contrasts earlier Bitcoin-channel micropayment experiments with modern L2 fees on Base. The commercial claim is not that fees are zero; it is that they are low enough for API-priced calls. zFinia records this as a market precondition, not as a fee oracle.

Why it matters

If L2 fees spike, x402’s per-call business model degrades before the protocol text changes.
