Sort a list — or an array of objects by one of its keys — the way you actually want. Natural (alphanumeric) ordering puts file2 before file10 and v1.9 before v1.10, the way humans expect; alphabetical, numeric and by-length orderings are also built in, each ascending or descending, with an optional case-insensitive mode. Items can be plain strings (comma- or newline-separated) or a JSON array; for objects, give the property to sort by and rows missing it go last. Perfect for file and version lists, leaderboards and tables, tidying user input and any UI that shows sorted data. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from set operations and CSV tooling.

Lines API
Operate on text line by line. The transform endpoint sorts lines (natural / numeric-aware, ascending or descending, case-insensitive), removes duplicate lines, reverses their order, numbers them, trims whitespace and drops blank lines — and the operations chain in the order you list them, so trim → remove blanks → dedupe → sort happens in a single call. The count endpoint reports line statistics: total, blank, non-blank, unique and duplicate counts plus the longest, shortest and average line length. Perfect for cleaning up lists and logs, deduplicating, preparing data and tidying pasted text. Pure local computation — no key, no third-party service, instant; up to 500,000 characters via POST. Live, nothing stored. 3 endpoints. Distinct from word wrapping, sorting of JSON lists and CSV tooling.

CSV API
A fast, fully-local CSV data toolkit: parse CSV into typed row objects (RFC-4180), compute per-column statistics (count, unique, type and top values, and for numeric columns min, max, mean, median and sum), remove duplicate rows by all or a subset of columns, sort by a column with numeric-aware ordering, and filter rows by a condition (equals, not-equals, greater/less than, contains, starts-with, empty, not-empty). Every endpoint accepts input via the query string or the request body, up to 2 MB, and returns both row objects and a CSV string. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for data wrangling, ETL, analytics preparation, spreadsheet tooling and data cleaning. (For plain CSV to JSON conversion, see the oanor JSON API.)

Set Operations API
Treat lists as sets. Compute the union, intersection, difference or symmetric difference of two lists; deduplicate a single list; and compare two lists to learn whether one is a subset of the other, whether they are equal as sets, whether they are disjoint and how many items they share. Items can be plain strings (comma- or newline-separated) or arbitrary JSON values, and an optional case-insensitive mode treats differently-cased strings as equal. Order is preserved (first occurrence wins). Perfect for data wrangling and reconciliation, tag and permission maths, deduplication, A/B list comparison and ETL. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from CSV/JSON toolkits — this is pure set logic.

Book Reader Stats API
Live reader-community stats for books from Open Library (the Internet Archive's open book catalog) — no key, nothing stored. This is the reading-community view of a book: how readers rate it and how many want to read, are reading or have already read it, distinct from the plain book-catalog and reading-trends APIs in the catalogue — this is the community-engagement layer, not the bibliographic record. The book endpoint returns a title's reader stats: the average rating, the full 1-5 star distribution, and the reading-log counts (want-to-read, currently-reading, already-read), with its authors, first-published year and subjects. The search endpoint searches books and returns each match with its rating and want-to-read count, so you can find a work and its Open Library id. The author endpoint returns an author's profile — work count, top work and dates. Build reading dashboards, book-recommendation widgets, "most wanted" charts and community-sentiment tools on top of real Open Library data. Look up a book by its Open Library work id (work=OL27448W) or by title (title=the hobbit); reading-log counts come from the community's bookshelves.
