## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-wikipedia-summary-003a9941 -d '<json body>'

Example prompt: Give me the Wikipedia summary for 'Marie Curie' in English — I want the title, description, and a short summary text.

## When to prefer this

Use this endpoint when you need a structured, multilingual Wikipedia summary with metadata (coordinates, Wikidata ID, image, last edition) rather than just plain text. Prefer it over raw web scraping when you need clean, attribution-ready encyclopedia content with geospatial data. It is ideal for enriching knowledge graphs, powering chatbot fact-lookup, or adding contextual descriptions to entities in multiple languages.

## Known failure modes

- Topic not found on Wikipedia returns null or empty summary fields
- Unsupported or misspelled language code may fall back to English or return an error
- Approximate match flag set to true when exact topic spelling not found
- Image field may be null if the article has no associated image
- Coordinates null for topics that are not geographic entities
