Your API should make money while you sleep. Kobaru makes your API payable by machines—AI agents, automated scripts, and developer tools can pay fractions of a cent per request, something credit cards cannot do.You receive USDC (a dollar-pegged stablecoin) directly in your wallet, with funds available in seconds. No monthly fees. No minimum transactions. No chargebacks.Micropayments that work - Charge $0.001 per request profitably (impossible with Stripe's $0.30 minimum)
Global from day one - Any machine with a wallet can pay you, no country-by-country setup
Instant settlement - Funds in your wallet in seconds, not days
Why Kobaru?#
Traditional payment processors charge high fees and require complex integrations. Kobaru enables true micropayments with global reach from day one.| Traditional payments | Kobaru |
|---|
| $0.30 + 2.9% minimum per transaction | Fractions of a cent per request |
| Days to settle | Sub-second finality on Solana |
| Complex integration and compliance | Drop-in middleware or zero-code proxy |
| Geographic restrictions and currency conversion | Global payments, single currency (USDC) |
| Not viable for micropayments | Built for micropayments |
Integration options#
Kobaru offers four integration approaches to fit different needs and technical requirements. Choose the one that works best for your situation.| Option | Best for | Code changes | Setup time |
|---|
| Transparent Proxy | Quick start, any backend, legacy APIs | None | 5 minutes |
| Standard SDK | Full control, TypeScript/Node.js, Go or Python | Middleware addition | 30 minutes |
| Advanced SDK | Sessions, budgets, analytics | Coming soon | - |
| Direct API | Any language, custom implementations, enterprise workflows | Full implementation | 1-2 hours |
Transparent proxy#
No code changes required. Configure your API in the Kobaru console, and your endpoints become accessible through our payment-gated proxy. This option operates at the network edge, handling authentication and validation automatically.https://access.kobaru.io/your-service/endpoint
Standard SDK#
Add payment middleware directly to your Node.js, Go or Python application. Fully compliant with the x402 v2 protocol, this approach ensures ecosystem-wide compatibility while giving you control over your infrastructure.Best for: TypeScript/Node.js, Go or Python applications, developers who want full control, dynamic pricing scenarios.Advanced SDK (coming soon)#
Goes beyond the x402 protocol with powerful features for production workloads: multi-request sessions, time-based access models (e.g., $0.05 per 30 seconds), budget controls for AI agents, and real-time analytics.Best for: High-volume APIs, autonomous AI agent integration, enterprise analytics requirements.Direct API#
Raw JSON/REST endpoints for complete control over the payment flow. Build custom implementations in any programming language by calling Kobaru's verification and settlement endpoints directly.Best for: Backends on other languages (Rust, Java), enterprises building proprietary payment workflows, intricate internal orchestration requirements.
How payments work#
When a client requests your paid API without payment:1.
Your API returns HTTP 402 with payment options
2.
Client signs a Solana or EVM transaction
3.
Client resubmits with payment proof
4.
Kobaru verifies the payment
5.
Your API returns the data
