+# Python API for Managing Runs
+
+Trackio provides a Python API class (`trackio.Api()`) that allows you to programmatically manage runs in your projects. This API is similar to `wandb.Api()` and provides methods to delete runs, move runs between projects, and access run information.
+
+**Note:** This is different from [Trackio as an API Server](api_mcp_server.md), which runs the Trackio dashboard as a web server with API endpoints. The Python API (`trackio.Api()`) is a client-side interface for managing runs in your local Trackio database.
+
+## Basic Usage
+
+```python
+import trackio
+
+# Initialize the API
+api = trackio.Api()
+
+# Get all runs in a project
+runs = api.runs("my_project")
+
+# Access individual runs
+for run in runs:
+    print(f"Run: {run.name}, Project: {run.project}")
+    print(f"Config: {run.config}")
+
+# Or access by index
+first_run = runs[0]
+```
+
+## Deleting Runs
+
+```python
+api = trackio.Api()
+runs = api.runs("my_project")
+
+# Delete a specific run
+run = runs[0]
+success = run.delete()  # Returns True if successful
+```
+
+## Moving Runs Between Projects
+
+```python
+api = trackio.Api()
+runs = api.runs("source_project")
+
+# Move a run to a different project
+run = runs[0]
+success = run.move("target_project")  # Returns True if successful
+
+# After moving, the run object's project is updated
+print(run.project)  # "target_project"
+```
+
+When you move a run, all associated data is transferred:
+- All metrics and logs
+- Run configuration
+- System metrics
+- Media files (images, videos, audio)
+
+The run is completely removed from the source project and added to the target project.
+
+## API Reference
+
+### Api
+
+Main entry point for the Trackio Python API.
+
+```python
+api = trackio.Api()
+```
+
+#### Methods
+
+- **`runs(project: str) -> Runs`**: Returns a collection of runs for the specified project. Raises `ValueError` if the project doesn't exist.
+
+### Runs
+
+A collection of runs that supports iteration and indexing.
+
+```python
+runs = api.runs("my_project")
+len(runs)  # Number of runs
+runs[0]    # First run
+for run in runs:  # Iterate over runs
+    ...
+```
+
+### Run
+
+Represents a single run in a project.
+
+#### Properties
+
+- **`id`**: The run name (same as `name`)
+- **`name`**: The run name
+- **`project`**: The project this run belongs to
+- **`config`**: The run's configuration dictionary (lazy-loaded)
+
+#### Methods
+
+- **`delete() -> bool`**: Deletes the run from its project. Returns `True` if successful, `False` otherwise.
+- **`move(new_project: str) -> bool`**: Moves the run to a different project. Returns `True` if successful, `False` otherwise. Updates the run's `project` property after a successful move.
+
+## Examples
+
+### List all runs across projects
+
+```python
+import trackio
+from trackio.sqlite_storage import SQLiteStorage
+
+api = trackio.Api()
+
+# Get all projects
+projects = SQLiteStorage.get_projects()
+
+# List runs in each project
+for project in projects:
+    print(f"\nProject: {project}")
+    runs = api.runs(project)
+    for run in runs:
+        print(f"  - {run.name}")
+```
+
+### Clean up old runs
+
+```python
+api = trackio.Api()
+runs = api.runs("my_project")
+
+# Delete runs older than a certain date
+from datetime import datetime
+cutoff_date = datetime(2024, 1, 1)
+
+for run in runs:
+    if run.config and "_Created" in run.config:
+        created = datetime.fromisoformat(run.config["_Created"])
+        if created < cutoff_date:
+            run.delete()
+            print(f"Deleted old run: {run.name}")
+```
+
+### Organize runs by moving them
+
+```python
+api = trackio.Api()
+
+# Move all runs from "experiments" to "archive"
+source_runs = api.runs("experiments")
+for run in source_runs:
+    run.move("archive")
+    print(f"Moved {run.name} to archive")
+```
