Kobaru
An x402 micropayment gateway and transparent proxy that adds pay-per-request paywalls to existing APIs without backend rewrites.
Last commit Feb 11, 2026 · ★ 4
Overview
Kobaru is an x402 micropayment gateway that lets developers monetize existing APIs via a transparent proxy and SDKs, with per-request and dynamic pricing. Clients/agents receive a standard x402 challenge and settle on Solana, Base, or SKALE, with payment validated at the gateway edge. It provides an open-source API Paywall Cookbook. Positioned for agent-to-API commerce.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
