Welcome to ShadowFeed

ShadowFeed is a decentralized data marketplace built on Stacks (Bitcoin L2) where AI agents autonomously discover and purchase real-time crypto intelligence using the x402 payment protocol.

Quick Example​

import { ShadowFeed } from 'shadowfeed-agent';

const sf = new ShadowFeed({
  privateKey: process.env.AGENT_PRIVATE_KEY,
  network: 'mainnet',
  agentName: 'My Agent',
});

// Discover all available feeds
const feeds = await sf.discover();

// Buy data — payment is automatic
const result = await sf.buy('whale-alerts');
console.log(result.data);

How It Works​

  1. AI Agent Discovers Feeds — Agent calls /registry/feeds to browse 16+ data feeds with pricing
  2. Agent Requests Data — Agent sends GET /feeds/whale-alerts. Server returns HTTP 402 Payment Required
  3. Automatic Payment — SDK auto-signs a STX transaction and retries the request
  4. Data Delivered — Agent receives real-time crypto intelligence. TX verifiable on Hiro Explorer
