Returns the latest capture by default, one UTC `date`, or a `startDate`/`endDate` range. Each row is `capturedAt`, `lab`, and `indexPerMtok`. The value is the token-weighted blend of that hour's sample. It is not the settled daily print from `GET /api/otpi`. Access matches that route: without a key, the free tier covers `anthropic`, `openai`, `google`, and `deepseek` for the trailing 3 months. A key unlocks all 11 labs and the full history. The response includes `access: "public-3mo" | "premium" | "full"`. ## Overview The hourly sample of the Ornn Token Price Index. Each row is the capture time, the lab, and `indexPerMtok`. This is the token-weighted blend of that hour's sample. The settled daily print remains [`GET /api/otpi`](https://data.ornn.com/docs/api-reference/token-prices/get-the-latest-token-price-index-by-lab). Access is the same: without a key, `anthropic`, `openai`, `google`, and `deepseek` for the trailing 3 months. A Premium or Full key unlocks all 11 labs and the full history. ## OpenAPI ````yaml openapi.yaml GET /api/otpi/hourly openapi: 3.1.0 info: title: Ornn Data API version: 1.0.0 description: > Read-only REST API for GPU and memory market data.
