# LarryBuildsAI Use Now Guide

Pick the product by the buyer question:

- Launching or listing a paid x402/MCP route? Use GateCheck.
- Deciding whether an agent should buy the next paid tool call? Use Signal Desk.
- Buying one public domain or URL result? Use ResultRail.

## GateCheck

Paste the paid route or seller homepage and get a buyer-readable answer: what is live, what is priced, what discovery files exist, what looks risky, and what should be fixed before spend.

- Start here: Use the GateCheck Readiness tool first when the question is whether a paid route is discoverable, priced, documented, and claim-safe.

- Claim boundary: Routeability evidence only; no marketplace approval, security audit, settlement proof, revenue, adoption, or endorsement claim.

## Signal Desk

Give Signal Desk the task an agent is about to run and it returns a small decision receipt: the sensible route, a budget boundary, proof to request, and when to stop.

- Start here: Use Agent Route Quote first when the question is whether the next paid tool call is worth buying.

## ResultRail

Ask for one public domain or URL result, inspect the quote and success contract first, then buy the result only when the source and price make sense.

- Start here: Use Result Quote first when the question is exactly what result will be bought and what counts as success.
