honeyhive

HoneyHive Python SDK - LLM Observability and Evaluation Platform

HoneyHive

Main HoneyHive API client.

Provides an ergonomic interface to the HoneyHive API with both sync and async methods.

Example::

client = HoneyHive(api_key="your-api-key")

# Sync
configs = client.configurations.list()

# Async
configs = await client.configurations.list_async()

Attributes:

Name	Type	Description
configurations		API for managing configurations.
datapoints		API for managing datapoints.
datasets		API for managing datasets.
events		API for managing events.
experiments		API for managing experiment runs.
metrics		API for managing metrics.
sessions		API for managing sessions.
