# GateCheck by LarryBuildsAI Product Card

## Positioning

Preflight checks for paid agent tools: seller-readiness evidence, unpaid `402` paid-path probes, MCP/OpenAPI discovery checks, launch-pack artifacts, and bounded receipts before marketplace listing.

## Buyer

- x402 API sellers preparing to list paid endpoints.
- MCP server builders adding paid-call surfaces.
- Agent marketplaces and tool directories reviewing whether a paid tool is discoverable, payable, and claim-bounded.

## Pain

Paid agent tools are hard to buy or route when agents and reviewers cannot quickly verify public manifests, OpenAPI paths, price surfaces, unpaid `402` behavior, MCP discovery, and safe listing language.

## Offer

GateCheck turns public metadata into bounded readiness evidence, report artifacts, launch copy, buyer FAQs, retest commands, and deterministic receipts. Agent Tool Readiness Checker and x402 Resource Scanner remain descriptive aliases. Boundary Guard x402 remains the legacy receipt layer and xpay slug.

## Safe Claim

Checks public metadata and optional unpaid `402` challenge behavior for x402/MCP readiness, then generates buyer-readable artifacts with explicit claim boundaries.

## Claim Boundary

No signing. No spend. No customer secrets. No marketplace endorsement claim. No security certification. No KYC/AML/reputation claim. No downstream execution proof. No settlement proof unless this service observed and settled its own x402 gate.

## Best Next Distribution Step

Refresh xpay display/listing metadata to use `GateCheck by LarryBuildsAI` while preserving slug `boundary-guard-x402`, payout settings, auth, and prices.
