### `verify_storefront` (~627 tokens)

Verify Storefront Legitimacy

Checks whether a merchant storefront looks like the same legitimate entity it appeared to be recently, BEFORE an agent commits payment to it.

This is the mirror image of merchant-side agent-verification protocols (e.g. Visa's Trusted Agent Protocol): those let a merchant confirm an incoming agent is legitimate. This tool lets the AGENT confirm the MERCHANT is legitimate before paying.

It does NOT guarantee a storefront is safe - it is a fast, explainable pre-purchase signal built from free public data sources (domain registration history via RDAP, SSL certificate issuance history via Certificate Transparency logs, HTTPS validity, and a known-scam-domain check). Treat a "high" risk result as a strong reason to pause and get human confirmation before paying, and a "low" risk result as one input among others, not a guarantee.

Args:
  \- domain (string): the bare domain of the storefront to check, e.g. "example-shop.com"

Returns:
  {
    "domain": string,
    "trustScore": number,       // 0-100, higher = more trustworthy
    "riskLevel": "low" | "medium" | "high" | "unknown",
    "confidence": "low" | "medium" | "high",  // how many signals could actually be resolved
    "reasons": string[],        // human-readable explanation for the score
    "recommendation": "proceed" | "pause_for_confirmation" | "do_not_proceed",
    "recommendationReason": string,  // one-line explanation of why this recommendation was made
    "signals": { ...raw signal data for audit/debugging... },
    "checkedAt": string         // ISO timestamp - this is a point-in-time result, do not cache it
  }

Recommendation values and suggested agent behavior:
  \- "proceed": trust score is high with high confidence — complete the transaction silently, no user confirmation needed
  \- "pause_for_confirmation": score is borderline or confidence is insufficient — pause and show recommendationReason to the user before completing payment
  \- "do_not_proceed": domain matched a scam list or trust score is…

Input parameters:

- `domain` (string, required): The bare domain of the storefront to verify, e.g. 'example-shop.com'. Strip protocol and path if given a full URL.
