Returns the latest settled day by default, a specific `date`, or a `startDate`/`endDate` range. Use `lab` to filter to a single lab. Without a key, the free tier covers 4 labs — `anthropic`, `openai`, `google`, `deepseek` — for the trailing 1 month (the same free window on index.ornn.com); other labs and older history require an API key. The response includes `access: "public-1mo" | "full"`. ## Overview The Ornn Token Price Index (OTPI): a daily, volume-weighted blended price per million tokens for each major model lab.
