It is ideal for one-off lookups, ad-hoc agent workflows, or pay-as-you-go competitive intelligence pipelines. The optional 'previous' field makes it especially powerful for change detection — pass the prior snapshot and the service can highlight drift. Prefer it over browser-extension tools when you need machine-readable output, and over enterprise solutions when volume is low and signup friction is undesirable.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-13T00:41:04.271Z","isFirstParty":false,"canonicalSlug":"tech-detect-technology-stack-detection-via-x402-35a93e11"}
