Is opencidian live?

Yes — it answered the hub's last check (checked 12h ago). It answered 100% of checks over the last 30 days.

Is opencidian free to use?

Yes — the hub reached it with no key and no payment.

What tools does opencidian have?

7 tools: annotate_text, lookup, get_character, words_with, search_meaning, suggest_correction, about.

Is opencidian safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• annotate_text unknown 12h ago

  Splits Chinese text into words (longest match against the dictionary) and gives each its pinyin, Hán Việt per character, Vietnamese and English senses and entry `id`. `kind` is word, unknown (Chinese not in the dictionary: say so) or other (punctuation, Latin, digits). `otherReadings` > 0 means the word has more readings than the one shown: look it up when the reading matters. The split is by dictionary match, not grammar, and can be wrong (哪国人 comes out 哪 + 国人): check a split that changes the meaning.

• lookup unknown 12h ago

  Dictionary entries for a Chinese word, a pinyin syllable or a Vietnamese word: simplified and traditional forms, pinyin, Hán Việt per character (Thiều Chửu), Vietnamese senses (CVDICT), English senses (CC-CEDICT), HSK level. Every field carries `src`, the source it came from. `kinds` says how the query was read and each entry's `match` which reading found it. `vi: null` means CVDICT has no Vietnamese for that word: say so, don't translate the English as if it were the dictionary's. No entries means the word isn't in the dictionary: say so, don't guess.

• get_character unknown 12h ago

  Everything known about one character: Hán Việt readings (Thiều Chửu first, Unihan when Thiều Chửu has none), pinyin readings, a short English gloss, stroke count, radical, its parts (decomposition) and how it was formed (etymology: the meaning part and the sound part, each with its Hán Việt), and its traditional or simplified forms. Every field carries `src`. For the words a character is in, use words_with; for a character used as a word, lookup.

  Vietnamese or English → Chinese: entries whose Vietnamese (CVDICT) or English (CC-CEDICT) senses match the meaning, HSK words first. These are candidates, not one translation: compare their senses and HSK levels before picking one, and say when several fit.

• suggest_correction unknown never probed

  Sends a correction for a wrong or missing value (Hán Việt, Vietnamese meaning, English, pinyin, a missing word) as a public GitHub issue in OpenCidian/opencidian-data; a maintainer reviews it, nothing changes in the data until then. Returns the issue number and link. Only use it when the user asks to report a mistake or agrees to, with evidence from a dictionary or textbook, never for a guess. The issue is public: put no personal details in it. A few per minute for all callers together.
