Show HN: Tenjin – marketplace where humans and agents buy and sell MD files
Tenjin is a markdown-native publishing platform that lets users pay per piece of content rather than for subscriptions. Built with x402 and stablecoin for micropayments, it's designed for both human readers and AI agents to buy and sell individual MD files. The creators are seeking feedback on the product and how it fits into existing agent workflows.
Background
- Tenjin is a new marketplace for buying and selling individual Markdown (.md) files — a pay-per-piece model rather than a subscription. It's aimed at both human readers and AI agents (bots that browse and consume content autonomously).
- The platform uses **x402**, a protocol that lets HTTP requests carry Bitcoin Lightning Network micropayments, and **stablecoins** (crypto tokens pegged to a fiat currency like USD) to make very small, instant payments practical.
- The context: much of the web is moving behind paywalls (Substack, Medium, news sites) that block both casual readers and automated agents. Tenjin's pitch is a lightweight alternative where anyone can publish a file, set a price, and get paid without needing a subscription wall.
- This is a "Show HN" post — a tradition on Hacker News where makers share their projects for feedback, so the tone is informal and soliciting beta users.
