Building the Future of Programmable Payments: Why x402?
Why we are building the Kobaru facilitator for the x402 protocol. Solving the 'HTTP 402 Payment Required' problem for the modern web.
The web has a missing piece. Since its inception, the HTTP status code 402 (Payment Required) has been "reserved for future use." Using x402, Kobaru bring new technologies that modern businesses demand.
The Problem: Friction as a Barrier
Traditional payment gateways were designed for the "shopping cart" era. They are heavy, involve high fixed fees, and require complex onboarding. If you are a developer building an AI agent or a high-frequency API, paying $0.30 + 3% per request is not just expensive—it's technically and economically impossible.
The Solution: The x402 Protocol
The x402 protocol is our implementation of a streamlined, programmable payment layer. By leveraging high-performance blockchains like Solana, Base, and SKALE, we enable:
- Micro-transactions: Settling amounts as low as $0.01 without losing 50% to fees.
- Zero-Latency Auth: Payments that act as authentication headers.
- Developer-First Integration: No redirects, no bloated SDKs. Just nice and clean code.
What to Expect from this Blog
This space is where we will document the evolution of the Kobaru facilitator. We aren't here to post "marketing fluff." You can expect:
- Technical Deep Dives: How we handle state machine consistency across chains.
- The API Cookbook: Practical examples in popular languages like Go, Python, Rust, and TypeScript to monetize your services.
- Protocol Updates: New features on the x402 standard.
- Dogs. We just love dogs!
We are building for the developers who are tired of the excessive weight of legacy finance. Welcome to the lean, fast, and programmable future.
