Error Handling
Errors are caught and returned as structured JSON responses:
{
"error": True,
"message": "ATTOM API error: 400 Bad Request",
"status_code": 400
}
- API errors: HTTP errors parsed from ATTOM API responses
- Network errors: Connection failures wrapped in APIError
- Config errors: Missing API key raises ConfigError at startup
- Tool layer: Catches APIError and returns error dict (never raises)
