POST https://text.halowerk.com/v1/anki-deck · 2 observations
Writes a real Anki package: an SQLite collection in the classic schema version 11 (collection.anki2, importable by Anki 2.1 desktop, AnkiDroid and AnkiMobile) with one note type (Basic or Basic and reversed card), one deck, notes with checksum (csum) and sort field, one new card per template, packed with an empty media map into a ZIP. Note GUIDs are derived from deck name and front text, so re-importing an updated deck updates notes instead of duplicating them.

POST https://text.halowerk.com/v1/contradiction-detect · 2 observations
English only. The document is split into sentences; candidate pairs share at least one content word (Snowball stop words removed) and are ranked by the number of shared content words, at most max_pairs (default 100). Each candidate pair is scored in both directions with cross-encoder/nli-deberta-v3-xsmall (Apache-2.0; DeBERTa-v3-xsmall, MIT; trained on SNLI, CC BY-SA 4.0, and MultiNLI; model card: SNLI test accuracy 91.64 %, MNLI mismatched 87.77 %), run locally from the fp32 ONNX export of the…

POST https://text.halowerk.com/v1/corpus-overlap · 2 observations
Text reuse detection with word shingles (Broder 1997): text and corpus documents are segmented into words (Unicode, NFKC, lower case); every run of n words (default 5) is hashed (32-bit FNV-1a) and compared through a hash index of the text. Matching shingles are chained along diagonals into maximal passages, verified word by word against hash collisions and kept from min_passage_words (default 8) words on; each passage reports start and end offsets in the text and in the document.

POST https://text.halowerk.com/v1/plural-rules-check · 2 observations
Uses Intl.PluralRules (CLDR plural rules as shipped with ICU) to get the cardinal and ordinal categories of the locale with sample numbers. ICU MessageFormat messages are parsed with a full parser; for every plural or selectordinal argument it reports missing categories, categories the locale never uses, explicit =N cases and the required other branch.

POST https://text.halowerk.com/v1/quote-in-source · 2 observations
Quote and source are normalised with an offset map back to the original source: Unicode NFKC, case folding, all quotation marks, apostrophes and dashes unified, whitespace collapsed, soft hyphens removed and line-end hyphenation joined (gekün-\ndigt -> gekündigt). Omission marks ([...], (...), ..., …) split the quote into segments that must occur in order.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
