This lets you instantly search and verify packages without ever hitting a live registry rate limit. Clicking a package in the UI still fetches its extended live details securely via a side-panel. ## Live explorers & docs * **Home:** [data.amit.is-a.dev](https://data.amit.is-a.dev) * **NPM Explorer:** [data.amit.is-a.dev/npm](https://data.amit.is-a.dev/npm) * **PyPI Explorer:** [data.amit.is-a.dev/pypi](https://data.amit.is-a.dev/pypi) * **API Docs (live):** [data.amit.is-a.dev/docs](https://data.amit.is-a.dev/docs) ## How the backend works The backend runs on **FastAPI**, serving static `.csv` snapshots pulled securely from HuggingFace datasets. * **SQLite indexing** — on first boot, the server downloads the multi-gigabyte dataset and builds an optimized, indexed SQLite database (WAL mode) * **Speed** — because the dataset is localized, `/search` and `/browse` respond in milliseconds * **Rate limiting** — strict limits (10 requests/minute, 100/hour) protect the free-tier infrastructure, enforced via `slowapi`; developers can request an `X-Bypass-Token` via a GitHub issue * **Ranking logic** — search results are ranked `0` exact match → `1` starts with query → `2` contains query * **Limitation** — as a frozen archive, packages published or deleted after April 2026 aren't indexed ## Get started * [Quick Start](/osma/quickstart) * [NPM API Reference](/osma/npm-api) * [PyPI API Reference](/osma/pypi-api) * [Utility Endpoints](/osma/utility) * [Notes, Limits & FAQ](/osma/notes)
