It differs from the sibling Delx Sentence Case endpoint, which applies sentence-level rather than word-level capitalization.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-20T12:45:51.147Z","isFirstParty":false,"canonicalSlug":"delx-title-case-c05bf40a"}
