# GateCheck by LarryBuildsAI Product Card

## Positioning

Routeability proof before paid agent tools: buyer-readable evidence from unpaid `402` challenges, MCP/OpenAPI discovery, pricing/resource metadata, launch-pack artifacts, and bounded receipts before marketplace listing or agent spend.

## Buyer

- Buyer-agent builders deciding whether to route spend into a paid endpoint.
- 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, routeable, and claim-bounded.

## Pain

Discovery tells buyers a route exists, but not whether an agent should spend on it. Paid agent tools are hard to route when agents and reviewers cannot quickly verify public manifests, OpenAPI paths, price surfaces, unpaid `402` behavior, MCP discovery, remaining risk, and expected after-payment proof.

## Offer

GateCheck turns public metadata into bounded routeability 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.

## Public Status

GateCheck public discovery, product-scoped MCP metadata, xpay proxy/portal surfaces, and marketplace packets are live. External directories may still require their own review, ranking, or indexing cycles.
