# Firefly III
Firefly III is a self-hosted personal finance manager. This skill provides API access for managing finances.

## Common Tasks
### Get spending by category

```

```bash
curl "$BASE/search/transactions?query=groceries&limit=25"

## Error Handling
- `422 Unprocessable Entity`: Check required fields in error response
- `401 Unauthorized`: Token expired or invalid
- `404 Not Found`: Resource doesn't exist
## Tips
- Use `source_name`/`destination_name` to auto-create expense/revenue accounts
- Categories are different from budgets (categories for classification, budgets for limits)
- Piggy banks require linking to an asset account
- Use rules to auto-categorize transactions on creation
