# Wikidata Entity Lookup

> Wikidata Entity 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).

## 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 wikidata-entity-lookup-7077abb6
```

Example prompt: Can you look up the Wikidata entity for 'Apple Inc.' and give me its Q-id, description, founding date, headquarters, and official website?

## When to prefer this

Choose this endpoint when you need structured, factual grounding data for a specific named entity — especially when you already have or can guess a Q-id, or need a consistent set of key claims (founder, population, coordinates, etc.) without parsing raw Wikidata SPARQL results yourself. Prefer it over Wikipedia search when you want machine-readable structured claims rather than prose snippets, and over full Wikidata SPARQL when you only need the standard set of common claims and want a simple REST call with per-lookup pricing.

## Known failure modes

- Entity not found in Wikidata — returns empty or error response
- Ambiguous name with multiple matching entities — may return the wrong entity
- Claims not present for that entity — fields will be null or absent
- Payment failure — x402 micropayment not completed, request rejected
- Rate limiting or server error from the upstream Wikidata API

## How this service works

Wikidata entity lookup: the Q-id, label, description, aliases, and key claims (instance of, country, population, inception, coordinates, official website, founder, headquarters) resolved to labels. Structured facts for grounding. $0.01 per lookup.

## Output

Returns the entity's Wikidata Q-id, canonical label, short description, aliases, and a set of key claims — including instance-of, country, population, inception date, geographic coordinates, official website URL, founder, and headquarters — all resolved to human-readable labels rather than raw Q-ids.
