This is the main tool for interacting with Zabbix. It requires multiple
iterations to achieve complex goals. Use other tools for guidance.

WORKFLOW:
1. If unsure about method/params: call zabbix_api_docs(method) first
2. If unsure about available methods: call zabbix_api_list() first
3. Execute the API call with this tool
4. If empty results or errors: iterate with different params/filters
5. Continue iterating until goal is achieved

COMMON PATTERNS:
- Finding an object requires 2+ calls (find ID, then get details)
- CPU usage example: Find host by name, get its items, filter CPU item, get history
- Empty results often mean wrong filters - try broader search first

Args:
    method: Zabbix API method (format: 'object.action').
    Examples: 'host.get', 'item.create', 'trigger.update'
    params: Method parameters (optional). For 'get' operations,
    specify 'output' to limit fields (default: ['name']).

Returns:
    JSON response from Zabbix API.

Examples:
# Simple query
zabbix_api('host.get', {'output': ['hostid', 'name']})

# Multi-step: Find host, then get items
# Step 1: Find host ID
hosts = zabbix_api('host.get', {'filter': {'host': 'my-srv-01'}, 'output': ['hostid']})
# Step 2: Get CPU items for that host
items = zabbix_api('item.get', {'hostids': ['12345'], 'search': {'name': 'CPU'}, 'output': ['itemid', 'name']})
# Step 3: Get history for specific item
history = zabbix_api('history.get', {'itemids': ['67890'], 'output': 'extend', 'history': 0, 'limit': 10})

Note:
- Use zabbix_api_docs() for method documentation
- Use zabbix_api_list() for available methods
- Iterate multiple times - complex queries need 2-5 API calls
