Search & web

Unified scientific literature search across arXiv (preprints), PubMed (biomedical), and Semantic Scholar (cross-field, with citation counts). Returns a flat array of papers with stable schema: source, sourceId, doi, title, authors, abstract, year, publishedAt, citationCount, url, pdfUrl. Partial failures surface in the errors array rather than failing the whole call. Optional filters: since (YYYY-MM-DD), sources (subset), limit (max 20 per source).

Execute live global web searches via the independent Brave Search index. Returns top ranked web pages, snippets, and page URLs. Provide ?q=your+query.

Compares one guide with caller-supplied candidate protospacers, weights mismatches in the guide’s final ten positions twice, applies a simple NGG PAM penalty, and ranks a transparent similarity score. It does not search a genome, model bulges, chromatin or nuclease-specific biology, and must not be used as a clinical or laboratory safety decision.

Loads a public https page, finds the requested form, fills your values into it in a real headless browser and reports what a submission would run into — without submitting. Each field is checked against what the page itself declares: whether it is required and empty, whether the value matches the field type for email, url, number, tel, date, time and color, and whether a select value is one of the offered options.
