# sina.bio > Sina Booeshaghi's personal website and public object index. The site exposes one read-only catalog for scientific objects, published essays, curated links, and quotes. Search results are intentionally small; fetch returns one object's complete public projection. Every result has a stable `id`, a `kind`, and a preferred human or citation `url`, which may be an external source. ## Collections - [Blog posts](https://sina.bio/api/search?kind=post&format=markdown): Published essays, newest first. - [Curated links](https://sina.bio/api/search?kind=link&format=markdown): Saved resources with concise summaries. - [Quotes](https://sina.bio/api/search?kind=quote&format=markdown): Verbatim quotations and their origins. - [Works](https://sina.bio/api/search?kind=work&format=markdown): Stable groupings of Sina's scientific work. - [Publications](https://sina.bio/api/search?kind=publication&format=markdown): Concrete citable versions of works. - [Authors](https://sina.bio/api/search?kind=person&format=markdown): People connected to indexed science. - [Claims](https://sina.bio/api/search?kind=claim&format=markdown): Atomic statements grounded in exact evidence. - [Results](https://sina.bio/api/search?kind=result&format=markdown): Broader syntheses over grounded claims. - [Software](https://sina.bio/api/search?kind=software&format=markdown): Software connected to indexed work. - [Sources](https://sina.bio/api/search?kind=source_document&format=markdown): Public source objects used for evidence. ## Search and fetch - [Search example](https://sina.bio/api/search?q=single-cell&format=markdown): Search every kind; add `kind` to narrow the results. - Fetch an object with `GET https://sina.bio/api/fetch?id=`. Both operations return JSON by default. Request `text/markdown` with the HTTP `Accept` header or add `format=markdown` for a compact Markdown representation. Both support `limit` and `offset`; responses report `total`. Search also supports a `kind` without `q`, which enumerates that collection. Scientific connections include their explanatory statement and any verbatim evidence spans. Evidence links to its source object. Generated candidates, private papers, local paths, credentials, and ingestion provenance are excluded from this accepted public snapshot.
