README
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- Stale/outdated data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

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.
