App Store Change Intelligence

Monitor App Store apps — new reviews, rating and version changes — with automatic negative-review alerts.

Agents pay peer-to-peer in USDC on Base using the native x402 protocol — no platform account, no payment processor, 0% commission. You can also use a monthly key. One key works across the whole Change Intelligence family.

One-call install for MCP clients

The npm wrapper prints ready-to-paste MCP config:

npx -y app-store-change-intelligence

Or Add the remote server manually to any MCP client (Claude Desktop, Cursor, Windsurf, …):

{
  "mcpServers": {
    "app-intel": {
      "url": "https://s-app.pixharvest.com/mcp"
    }
  }
}

Anonymous initialize / tools/list are free; paid tool calls return an x402 challenge.

Pay-per-call (x402)

Call a paid route without payment and you receive 402 Payment Required with a machine-readable PAYMENT-REQUIRED header (x402 v2) plus a v1 JSON body. The agent signs a USDC authorization, retries with the payment header, and the request settles on Base.
