Usage lookup

Dashboard

The Usage page lists every request with its time, model, token counts (including cache and reasoning), cost and latency. Filter by key, model and date range, and export the results.

Look up a key without signing in

Open the key usage lookup page and enter an API key to see its balance, quota usage and recent activity — handy when you share a key with someone else.

Via the API

Call with the key itself:

It returns the key's status, quota and usage. Add ?days=7 for daily usage over the last N days (1–90).

Usage in responses

Every response includes usage fields you can record in your own system:

Chat Completions: usage.prompt_tokens, usage.completion_tokens, usage.prompt_tokens_details.cached_tokens Anthropic Messages: usage.input_tokens, usage.output_tokens, usage.cache_read_input_tokens
