Wikexa
Knowledge your AI agent can actually afford to read. Every time your agent looks something up, it pays for about 15,000 tokens of markup to recover roughly 500 tokens of fact. You are billed for all of it — the navigation, the citation scaffolding, the edit links — and then your model throws it away. Wikexa did that reading already. You get the facts.
Documentation
Wikexa
Structured knowledge for AI agents. Wikipedia, Wikidata and Wiktionary as clean JSON instead of HTML. ~30x fewer tokens than fetching the page yourself.

Why
An agent fetching en.wikipedia.org/wiki/Apple_Inc. burns ~15,000 tokens of HTML
to recover ~500 tokens of facts. Wikipedia's own API returns wikitext, which is
barely better. One lookup() call here returns the facts directly.
Tools
| Tool | What it gives you |
|---|---|
lookup(entity, corpus?) | Structured facts + ~200-token summary. Resolves aliases and Q-ids. |
article(title, sections?, max_chars?, corpus?) | Full article as structured JSON — sections as an array, infobox as key/value. No HTML or wikitext. |
define(word, language?, pos?) | Dictionary definitions from Wiktionary — 8.15M entries across ~4,000 languages. Grouped by language, with etymology and pronunciation. |
search(query, limit?, corpus?) | Ranked matches blending relevance, pageviews, and exact-title matching. Up to 50 results. |
recent(topic?, hours?, limit?) | Recently changed articles — facts newer than your training cutoff. |
Every tool is also a REST endpoint backed by the same handler:
GET https://wikexa.com/v1/lookup?entity=Tim%20Cook
GET https://wikexa.com/v1/article?title=Apple%20Inc.§ions=History
GET https://wikexa.com/v1/define?word=serendipity&language=English
GET https://wikexa.com/v1/search?query=quantum%20computing&limit=5
GET https://wikexa.com/v1/recent?topic=election

Token control
article() takes sections and max_chars. Ask for the section you need
rather than the whole article. Empty fields are omitted from all responses to
minimize token usage.

licences. Paid plans buy service capacity and support, never content rights.
