Tech Detect — Technology Stack Detection via x402

Prefer this endpoint when you need no-signup, pay-per-call technology detection billed in USDC over x402, especially in automated agent pipelines where API key management is undesirable. Useful when you need confidence scores and evidence alongside raw technology names, or when scanning a moderate volume of domains without committing to a subscription. If you need bulk scanning of thousands of domains per day, a subscription-based alternative may be more cost-efficient.

• Domain is unreachable or returns non-200 — detection may be partial or empty
• Private/intranet domains that are not publicly accessible cannot be scanned
• Heavily obfuscated or minified sites may yield low-confidence or missing detections
• Rate limiting or bot-blocking on the target domain may prevent full evidence gathering
• Invalid URL format in the request body will return a validation error
• Insufficient USDC balance or x402 payment failure will result in a 402 rejection before scanning occurs
