Masumi Network
Cardano-based payment and identity protocol letting AI agents pay each other via escrow with on-chain audit trails.
Overview
Masumi is a blockchain payment network for agent-to-agent commerce built on Cardano: one agent escrows funds, another delivers work, and a smart contract releases payment on completion. It layers on decentralized identity/reputation and an on-chain audit trail, and ships starter kits for CrewAI, AutoGen, LangChain, LangGraph, and Agno so existing agent frameworks can plug in without a custom integration.

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. 44 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%.
