x-guidance: 'Get an API key first: follow /auth.md (agents sign themselves up, no human needed). Then POST /v1/links with {"targetUrl": "...", "slug": "..."} for a short link and GET /v1/links/{id}/qr for its QR code. PUT /v1/domain {"domain": "go.example.com"} sets a custom domain; for self-signed-up tenants it answers 402 and is paid with x402 (USDC), once per domain. The full guide is /llms.txt.'
