Tech Detect — Technology Stack Detection via x402

Choose this endpoint when you need real-time, per-call technology fingerprinting of a specific domain without committing to a subscription or managing API keys. It is ideal for agents that need on-demand stack detection for arbitrary URLs, competitive intelligence pipelines, sales enrichment workflows, or security recon tasks. The x402 pay-per-call model makes it cost-efficient for sporadic lookups. Prefer this over bulk crawling services when you need confidence scores and evidence per technology rather than just a list.

• URL is unreachable or returns non-200 status — detection may be incomplete or return empty results
• Domain uses heavy anti-bot protections — may reduce detection coverage
• Invalid or malformed URL input — returns validation error
• Payment failure over x402 — call is rejected before processing
• Previous observations schema mismatch — ignored or causes input validation error
• Site uses obfuscated or minified assets — version detection may be null
