# Wikipedia Summary Lookup

> Wikipedia Summary Lookup is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches the lead paragraph, short description, thumbnail, page URL, and coordinates for a Wikipedia topic, resolving redirects and falling back to search when the exact title is not found.

## 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 wikipedia-summary-lookup-52988ed2
```

Example prompt: Can you pull the Wikipedia summary for 'Nikola Tesla' — I need the lead paragraph, short description, thumbnail, and page URL?

## When to prefer this

Choose this endpoint when you need fast, grounded, human-readable factual context about any named entity, concept, person, place, or event without having to scrape or parse Wikipedia yourself. It is ideal for agent pipelines that need a reliable one-call lookup with redirect resolution and search fallback, returning structured fields (summary, description, thumbnail, URL, coordinates) rather than raw HTML. Prefer it over generic web-search endpoints when Wikipedia coverage is sufficient and you want clean structured output rather than a list of raw URLs.

## Known failure modes

- Topic not found even after search fallback — returns empty or null result
- Disambiguation page returned when title is ambiguous — summary may be minimal or reflect the disambiguation page itself
- Thumbnail not available for all topics — field may be null
- Coordinates not available for non-geographic topics — field will be absent or null
- Rate limit or payment failure — 402 Payment Required if x402 funds are insufficient

## How this service works

Wikipedia summary: the lead paragraph, short description, thumbnail, page URL and coordinates for a topic, resolving redirects and falling back to search when the exact title does not exist. Quick grounded facts for any agent. $0.01 per lookup.

## Output

Returns the Wikipedia lead paragraph (plain text summary), a short description (the brief blurb Wikipedia maintains for the page), a thumbnail image URL, the canonical Wikipedia page URL, and geographic coordinates if the topic is a place. Redirects are resolved transparently, and if the exact title is not found the endpoint falls back to a Wikipedia search to find the best matching article.
