The x402 Micropayments Standard & Cloudflare Edge

Announced in partnership with Coinbase, the Cloudflare Monetization Gateway enables edge-level payment verification and gating. AI agents pay in fractions of a cent per request directly over HTTP without account setup or API key management.

1. Eliminating Striped Friction

Standard credit card transactions carry a minimum fee of $0.30, making small-value API monetization (e.g. $0.001) impossible. Stablecoins over Layer 2 networks like Base or Solana resolve this with sub-cent network transaction fees.

2. HTTP 402 "Payment Required"

Reserved since 1999 for digital cash systems, HTTP 402 is activated by x402 as an open, vendor-neutral web standard that enables programmatic negotiation and verification within standard request headers.

3. Edge-Level Gatekeeping

By validating signed payment signatures directly at Cloudflare's edge, origin servers are protected from heavy traffic loads and DDOS threats. Your APIs and databases only receive validated, paid calls.
