# Apex Edge — x402-paid machine services

An MCP server for corpus search, code checks, inference, and utility calls paid through x402. Use it when an agent needs machine services billed per request.

## What it does

Apex Edge exposes MCP tools for hashing, UUIDs, Base64, time, pricing, corpus search, and code review. The server offers a free `tools/list`; tool calls use x402 billing. Its services include a 387-document research index, a 34-item static audit checklist, and an LLM security verdict for pasted code.

Requests go to `POST /mcp`. Payments use USDC on Base mainnet or Solana USDC-SPL, with no account or API key required. The package includes `client.py` for probing calls and a CI action for GitHub Actions. Paid calls will not complete without an x402 payment.

## Requirements
- Remote server: `https://apex-edge-coral.vercel.app/mcp`

## Install

```bash
gemini mcp add -t http apex-edge-x402-paid-machine-services https://apex-edge-coral.vercel.app/mcp
```

## When to use it
- search a document corpus for a topic
- run a static audit checklist on code
- request an LLM security verdict
- call a utility tool through MCP
- probe a paid endpoint from CI

## Example prompts
- Search the corpus for `monetization` through the MCP server.
- Review this code with the audit checklist and report the security issues.
- Call `hash` with the input `hello` and show the server response.
