Build a source-linked evidence pack with scholarly papers, bibliography and optional registered clinical trials. Metadata only, no invented findings.

Find and deduplicate scholarly papers from Crossref and Europe PMC. Use for literature discovery with DOI source links.

Inspect a business or project website for its published description, structured data and pricing, contact, documentation and social links. Reports source claims, not verified company facts.

Check up to ten DOI citations against source registries, compare optional titles, and expose publication update signals. Use to detect incorrect references.

Read up to three public static HTTPS webpages in one paid call for comparisons or multi-source context. All pages must succeed or the request is not settled.

Extract published JSON-LD and optional CSS-selector fields from a public static HTTPS page. Use for product data, organization metadata or repeatable structured extraction. No inferred values.

Read a public static HTTPS webpage as clean text with headings, links, timestamp and content hash. Use to ground an answer or ingest documentation. Respects robots.txt; no JavaScript or login.
