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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Observed record — 91 daily checks since 2026-07-26

100%of 91 checks since 2026-07-26 succeeded

Currently responding for 91 days

Succeeded: 91
Failed: 0
Their error: 0
Unattributed: 0

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. 37 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. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
