Shopify Change Intelligence

English · 简体中文

A zero-dependency Cloudflare Worker that monitors Shopify stores and sells change intelligence. AI agents pay automatically in USDC on Base via the native x402 protocol — no platform account, no payment processor, 0% commission.

npm: shopify-change-intelligence — npx shopify-change-intelligence prints the MCP client config for the hosted server.

What it does

Four tiers, from free data to a distilled answer:

  • GET /v1/snapshot?store=allbirds.com — free. Live catalog snapshot (count, price range, availability).
  • GET /v1/changes?store=allbirds.com — $0.05. Raw change list vs. the last stored snapshot: new/removed products, price up/down, restock/out-of-stock.
  • GET /v1/intel?store=allbirds.com — $0.50 ⭐. Full-catalog competitor intelligence report: price bands, median/range, top discounts & hikes, stock signals and auto-generated executive takeaways.
  • POST /v1/batch — $0.03 / store (max 50). Body {"stores":["a.com","b.com"]}; watches a whole competitor set in one call and returns per-store change counts.
  • GET /mcp — MCP (JSON-RPC over Streamable HTTP) exposing all four as tools. GET / — landing page. GET /v1 — JSON manifest. GET /health — health check.

When a paid route is called without payment the server returns 402 Payment Required with a base64-encoded PAYMENT-REQUIRED header. An x402-capable agent fetches a USDC settlement, re-sends it in the PAYMENT header, and the worker verifies and settles it through the Coinbase x402 facilitator.

Architecture

  • Runtime: Cloudflare Workers (native fetch, no frameworks, no npm dependencies).
  • Settlement: x402 protocol, Base mainnet (chainId 8453), USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.
  • Facilitator: https://x402.org/facilitator (/verify, /settle).
  • Storage (optional): Workers KV namespace INTEL_KV for historical snapshots. Without it the worker still runs; the free snapshot is always live and change detection reports against an empty baseline.

Deploy

npm i -g wrangler
wrangler login
wrangler kv namespace create INTEL_KV   # copy id into wrangler.toml
wrangler deploy

Set your own payout address and prices in src/worker.js (PAY_TO, PRICE_DEEP_USD, PRICE_INTEL_USD, PRICE_PER_STORE_USD).

Notes

  • Only public, unauthenticated /products.json endpoints are read.
  • Payment settlement is independent of discovery: to be found by agents, list the endpoint in x402/MCP directories.
