Crypto API Fixer

Auto-repair middleware for crypto trading bots.
Fixes API errors silently in <2ms — before your bot loses money.

One middleware. Ten error types. Zero headaches.

Why It Exists

Crypto trading bots break at 3 AM because of:

Rate limits (429/503)
Stale/outdated data
Broken JSON schemas
Auth failures
Price mismatches
Endpoint downtime
And more...

You sleep. Your bot freezes. You lose money.

Crypto API Fixer fixes it automatically.

Quick Start (for Humans)

git clone https://github.com/yourusername/crypto-api-fixer.git
cd crypto-api-fixer
pip install -r requirements.txt

# Train the system (one time)
python main.py --mode train

# Run the MCP server
python main.py --mode server

# Test
python main.py --mode test

Server runs on http://localhost:8080

For AI Agents (Claude / Cursor / Windsurf)

Add this to your MCP configuration:

{
  "mcpServers": {
    "crypto-api-fixer": {
      "url": "https://your-server-url/mcp"
    }
  }
}

The agent will automatically discover 10 specialized tools.
