Query and export Calls

Filter, sort, and export your W&B Weave Call data

In the Weave UI, you can export your data in multiple formats. It also shows the Python and cURL code that you can use to export the rows programatically. To export Calls:

1. Navigate to wandb.ai and select your project.
2. In the Weave project sidebar, click Traces.
3. Select multiple Calls that you want to export by checking the row.
4. In the Traces table toolbar, click the export/download button.
5. In the Export modal, choose Selected rows or All rows. Click Export.

Fetch calls programmatically

Python

To fetch calls using the Python API, you can use the client.get_calls method:

import weave

# Initialize the client
client = weave.init("your-project-name")

# Fetch calls
calls = client.get_calls(filter=...)

TypeScript

To fetch calls using the TypeScript API, you can use the client.getCalls method.

import * as weave from 'weave'

// Initialize the client
const client = await weave.init('intro-example')

// Fetch calls
const calls = await client.getCalls(filter=...)

HTTP API

The most powerful query layer is at the Service API. To fetch calls using the Service API, you can make a request to the /calls/stream_query endpoint.

curl -L 'https://trace.wandb.ai/calls/stream_query' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-d '{
