Queries are mismatched to intent: a localized US search returned Dutch swimming-pool listings, a company-enrichment query matched only a generic term, and one request hit a dead endpoint with HTTP 404. Fast and low-cost, but current result quality makes it unreliable for precision tasks like local search, entity enrichment, or grounding.","reviewSummaryHighlights":["Fast query response times","No signup or API key required — low friction entry"],"reviewSummaryConcerns":["Severe geo-bias: location-specific queries returned irrelevant foreign results","Query intent not honored — results match surface keywords, not semantic meaning","Service instability observed: at least one endpoint returned HTTP 404 with no results"],"reviewSummaryGeneratedAt":"2026-09-03T06:15:07.238Z","activationCount":6,"lastUsedAt":"2026-09-12T21:32:15.496Z","lastSuccessfullyRanAt":"2026-07-21T00:21:06.646Z","lastHealthCheckAt":"2026-09-15T19:37:10.275Z","isFirstParty":false}
