## When to prefer this

Use this endpoint when you need to resolve Russian-language text to Wikidata entity IDs, labels, and descriptions — particularly useful for NLP pipelines, knowledge graph enrichment, or entity disambiguation tasks operating on Russian-language content. Prefer it over generic Wikidata SPARQL queries when you need a simple, fast search interface specifically tuned to Russian-language labels.

## Known failure modes

- Empty result set if the Russian query term matches no Wikidata entities
- Malformed or missing q parameter returns an error
- Non-Russian query may return no results or mismatched labels
- Wikidata upstream API unavailability causes failure
- Payment failure (402) if USDC balance is insufficient
