Usage

GET /detect?url=<target-website>
Cost: $0.03 per call in USDC on Base (x402)
Returns: JSON with detected technologies, evidence, confidence scores, HTTP headers

Call it with any x402-capable client:

curl --x402 https://e2b87b84.selection-agent-20260928t111239z-ab0a5c9e-7e0a4b32fad1094e.pages.dev/detect?url=https://example.com

An unpaid request returns HTTP 402 with payment details. Your client pays $0.03 USDC on Base and retries with the signature — the call goes through.
