Academic literature from Crossref, the DOI registry itself. Search by topic, author or exact DOI and get normalised records with citation counts, journal, publisher, authors with affiliations, and an open-access flag, plus a cohort view: median citations, most-cited work and the year range. Filter by minimum citations, publication year or open access only.

App Store listing data for any app on any storefront: current and all-time star ratings with review counts, version, release notes, size, price, content rating, genres and release dates. Includes a version-sentiment read comparing the current version's rating against its all-time average, which is how you spot a release that damaged an app. Look up by numeric App Store id or search by name.

Turns a domain, company name or ticker into the official identifiers everything else joins on: SEC CIK, GLEIF LEI, Wikidata ID and SIC industry code, plus legal name, jurisdiction, HQ, whether it still files with the SEC, and its recent filing mix. Built to be called once per row over a list. Every source is free and redistributable, so results carry no vendor resale restriction.

FDA recall and enforcement records across drug, device and food, normalised into one shape with classification, reason, distribution scope and firm. Queryable by firm, product, classification and date. One product type returning nothing never fails the call — the three openFDA endpoints are independent and a gap in one is not a gap in the others.

Job postings read straight from a company's own applicant tracking system — Greenhouse, Lever, Ashby, SmartRecruiters, BambooHR or Recruitee. This is the source that job boards scrape, so there are no duplicates, no expired listings and no aggregator lag. Hiring is a demand signal: which teams a company is growing and where.

Screen any person or company against the US Treasury OFAC sanctions lists — SDN and Consolidated, primary names plus every recorded alias, 39,000 names in total. Handles the 'LAST, First' convention OFAC uses, strips legal suffixes so Ltd and Limited match, and returns exact, strong and possible hits with the sanctions programmes attached. Tuned to over-report rather than miss. Returns the list build date so you know how current the screen is.

Real insider conviction from SEC Form 4 filings. Classifies every transaction by its one-letter code, so an RSU vest is not reported as an insider buy and the automatic tax withholding that follows is not reported as a sale. Returns only codes P and S — the trades where someone chose to move money at the market price — plus cluster-buy detection when several insiders buy the same issuer within a window. Query by ticker or CIK.

Steam reviews scored by how long the reviewer actually played. A negative review from someone with 400 hours means something very different to one from a player with 12 minutes, and the headline percentage treats them the same. Also separates the lifetime rating from the recent one, which is how you spot a game that has just broken.

Decode any 17-character VIN into the vehicle it describes: make, manufacturer, model, year, series, body class, drive type, engine, fuel, transmission and assembly plant. NHTSA returns 140 mostly-empty fields; this strips the blanks, promotes the ones that matter and reports whether the check digit validated.
