# XGuard

XGuard returns normalized page evidence, structured product offers and deduplicated RSS/Atom digests. Start with xguard_execute {"intent":"demo"} for a free extraction result. For live work describe a supported intent with up to three public URLs, or ask for a technology feed digest. Call POST https://api.xguardgate.com/v1/execute (or xguard_execute) directly; discovery and quotes are optional. A paid call returns HTTP 402 with exact USDC price, Payment-Required and X-XGuard-Quote. A funded x402 v2 payer signs the requirements and retries the identical body, preserving X-XGuard-Quote. The server verifies and settles before source access. Source digests prove observed content integrity, not factual truth. Errors include repair.suggested_request. No search, OCR, general AI model or private API access is included. Legacy x402-paid tools and reusable upstream API credentials remain available through the documented compatibility routes.
