LiteLLM provides callbacks, making it easy for you to log your completions responses.

​
Using Callbacks

First, sign up to get an app ID on the Lunary dashboard. With these 2 lines of code, you can instantly log your responses across all providers with lunary: 
litellm.success_callback = ["lunary"]
litellm.failure_callback = ["lunary"]
Complete code 
from litellm import completion

## set env variables
os.environ["LUNARY_PUBLIC_KEY"] = "0x0"
# Optional: os.environ["LUNARY_API_URL"] = "self-hosting-url"

os.environ["OPENAI_API_KEY"], os.environ["COHERE_API_KEY"] = "", ""

# set callbacks
litellm.success_callback = ["lunary"]
litellm.failure_callback = ["lunary"]
