Task classification market share

Returns the market-share breakdown of OpenRouter traffic by task classification (e.g. code generation, web search, summarization) over a trailing time window.

Each classification reports its share of classified sampled requests (usage_share) and classified sampled token volume (token_share) as fractions between 0 and 1. The unclassified other bucket is excluded. Absolute volumes are not exposed because the underlying data is sampled.

Each classification also includes a models array listing the top models by request volume within that classification, with their within-tag usage and token shares.

Classifications are grouped into macro-categories (Code, Data, Agent, General) with aggregate shares provided for each.

Authenticate with any valid OpenRouter API key (same key used for inference). Rate-limited to 30 requests/minute per key and 500 requests/day per account.
