# LogSpanToolContent

# LogSpanToolContent

Content type for tool and API invocation spans.

## Overview

`LogSpanToolContent` captures external tool calls and API invocations. It is wrapped in a [LogSpanContent](/docs/reference/sdk/v2/python/types/LogSpanContent) union via the `actual_instance` pattern.

```python theme={null}
from adaline_api.models.log_span_tool_content import LogSpanToolContent
```

***

## Fields

<ParamField body="type" type="str" required>
  Must be `"Tool"`.
</ParamField>

<ParamField body="input" type="str" required>
  The input payload as a JSON string. Must be valid, parseable JSON (the result of `json.dumps()`).
</ParamField>

<ParamField body="output" type="str" required>
  The output payload as a JSON string. Must be valid, parseable JSON (the result of `json.dumps()`).
</ParamField>

***

## Construction Pattern

All span content is wrapped in [LogSpanContent](/docs/reference/sdk/v2/python/types/LogSpanContent) using the `actual_instance` parameter:

```python theme={null}
from adaline_api.models.log_span_content import LogSpanContent
from adaline_api.models.log_span_tool_content import LogSpanToolContent

content = LogSpanContent(
    actual_instance=LogSpanToolContent(
        type="Tool",
        input=json.dumps({"function": "search", "args": {"query": "weather"}}),
        output=json.dumps({"results": ["sunny", "72F"]}),
    )
)
```

***

## Example

```python theme={null}
import json
from adaline_api.models.log_span_content import LogSpanContent
from adaline_api.models.log_span_tool_content import LogSpanToolContent

tool_input = {"function": "get_weather", "args": {"city": "San Francisco"}}
tool_output = {"temperature": 68, "condition": "foggy", "unit": "fahrenheit"}

span.update({
    "status": "success",
    "content": LogSpanContent(
        actual_instance=LogSpanToolContent(
            type="Tool",
            input=json.dumps(tool_input),
            output=json.dumps(tool_output),
        )
    ),
})
```
