Why x402 Matters

The internet excels at distributing information but still struggles with distributing value. Coinbase x402 closes that gap, giving builders a native monetization primitive that works for media, APIs, communities, and autonomous agents. By extending HTTP 402 Payment Required into a live protocol, x402 lets any service price access per interaction while keeping user flows frictionless.

Unlock New Revenue Streams

• 402x Paywalls. Charge per article, video, or download without locking audiences into subscriptions.
• 402x APIs. Monetize machine learning, data, or SaaS endpoints with metered calls and real-time settlement.
• 402x Widgets. Drop in no-code payment buttons for donations, tips, or gated files.

Strengthen Ecosystem Trust

• Reduced Spam. Transactional fees discourage bots and low-quality submissions across forums or marketplaces.
• Transparent Economics. On-chain settlement gives participants auditable records of every payment event.
• Autonomous Collaboration. Humans and AI agents can compensate each other instantly for micro tasks or data usage.

Expand Global Access

• Borderless by Design. Coinbase x402 supports global stablecoin payments with minimal FX overhead.
• Accountless Onboarding. Users authenticate with value, not passwords, keeping privacy intact.
• Composable Stack. Developers can integrate x402 alongside existing auth, storage, or analytics services.

How Enterprises Benefit

• Launch new lines of business without reinventing billing or relying on heavy compliance flows.
• Experiment with pricing in minutes using x402 policy controls, then scale successful models across markets.
