It is ideal for agents that need to confirm URL integrity in structured payloads before downstream processing, and when auditability matters — the SHA-256 input hash and zero-retention guarantee make it suitable for privacy-sensitive workflows. Prefer it over general-purpose HTTP validation libraries when you want a hosted, chain-verifiable result.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-01T00:54:03.472Z","isFirstParty":false,"canonicalSlug":"delx-commerce-json-url-fields-check-3026bc72"}
