url2brain is the shared intelligence behind Kurage URL2AI Publisher and the open-source url2pub body. It analyzes a public URL, writes an announcement and a full article, and can publish through five real media routes. The OSS is free to self-host; hosted calls are metered at $1.00 through x402.
Improve url2brain once and both the human web app and the OSS agent workflow improve.
Human users sign in with X, paste a URL and publish through the visual URL2Pub workflow. After the test period each run costs ¥200 or 20,000 URLAI (your choice); during the test it is free and the first 1,000 users receive a 10,000 URLAI reward.
Authentication, UI, history and reward handling stay in the open-source body. The brain remains replaceable.
DeepSeek handles paid generation. The API has no caller social credentials; publishing uses controlled Kurage/EXBRIDGE destinations.
Every hosted path is $1.00 per request in USDC on Base.
