Check configured API keys for LLM backends — check_llm_api

This function inspects the current R session for configured API keys used by pairwiseLLM. It checks for known environment variables such as OPENAI_API_KEY, ANTHROPIC_API_KEY, and GEMINI_API_KEY, and returns a small tibble summarising which keys are available.

Usage

check_llm_api_keys(verbose = TRUE)

Arguments

verbose: Logical; if TRUE (default), prints a human-readable summary to the console describing which keys are set and how to configure missing ones.

Value

A tibble (data frame) with one row per backend and columns:

backend: Short backend identifier, e.g. "openai", "anthropic", "gemini", "together".
service: Human-readable service name, e.g. "OpenAI", "Anthropic", "Google Gemini", "Together.ai".
env_var: Name of the environment variable that is checked.
has_key: Logical flag indicating whether the key is set and non-empty.

Details

It does not print or return the key values themselves - only whether each key is present. This makes it safe to run in logs, scripts, and shared environments.

Examples

if (FALSE) { # \dontrun{
# In an interactive session, quickly check which keys are configured:
check_llm_api_keys()

# In non-interactive scripts, you can disable messages and just use the
# result:
status <- check_llm_api_keys(verbose = FALSE)
status
} # }
