## How to call it through Zero

## When to prefer this

Use this endpoint when you need structured, paragraph-level Wikipedia content for a known article title and want it returned as clean JSON rather than raw HTML. It is ideal for agents that need encyclopedic background information on a topic, want to cite a Wikipedia source URL, or need to ingest article text into a knowledge base. Prefer it over full web scraping when the target is always Wikipedia and you want consistent, schema-stable output at low cost ($0.01 USDC per call).

## Known failure modes

- Article title not found on Wikipedia — returns an error or empty result
- Ambiguous title matches multiple Wikipedia pages — may return unexpected article
- Wikipedia rate-limiting or unavailability — upstream fetch fails
- Misspelled or malformed title input — no match returned
- Non-English or redirect-only titles may not resolve correctly

## How this service works

Format conversion: Wikipedia's own REST API serves full rendered HTML, not JSON. This fetches an article's lead section (?title=) and returns clean, tag-free paragraph text as JSON.

## Output

A JSON object containing the article title, the Wikipedia source URL, an array of summary paragraph strings, and a timestamp of when the content was converted. This gives the agent structured, ready-to-use encyclopedic text for a given topic.
