GateCheck by LarryBuildsAI

GateCheck

Routeability proof before a paid x402 or MCP route is listed, promoted, wrapped, or sent agent traffic.

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 GateCheck Readiness $1.00 · Use the GateCheck Readiness tool first when the question is whether a paid route is discoverable, priced, documented, and claim-safe.

  • GateCheck Readiness $1.00 · GateCheck readiness: check whether an x402/agent-facing tool is ready for agent routing, marketplace listing, and paid-path monitoring, including public agent discovery surfaces (/llms.txt, /agents.txt, /.well-known/mcp.json, /mcp). Pass target plus optional tier, marketplace_url, expected_resources, and paid_path; deep/report tiers add unpaid 402 probing when paid_path is supplied. Tiers: quick $1, deep $5, report $10.
  • x402 Resource Scan $0.10 · Read-only scan of a public API/provider URL for x402, OpenAPI, pricing, and agent-discovery metadata. Pass url, and optionally marketplace_url plus expected_resources, to get a readiness score, issues, and fixes; no private endpoints are called.
  • x402 Paid-Path Health Probe $0.50 · Probe a public x402 paid endpoint without signing or paying, then parse the HTTP 402 challenge. Pass target plus optional expected network/asset/price to verify payment metadata and receive a deterministic health receipt.
  • x402 Launch Pack Generator $9.00 · Generate marketplace-safe launch assets for an x402/MCP seller: listing copy, buyer FAQ, checklist, approval packet, and claim boundaries. Pass target plus optional product_name, audience, primary_use_case, marketplace_url, and paid_path; service/premium tiers include readiness evidence. Tiers: single $9, service $29, premium $49.

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

Signal Desk by LarryBuildsAI

Signal Desk

Advisory buy, skip, stop, or ask-for-proof receipts before agents chain larger paid tools.

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 Agent Route Quote $0.03 · Use Agent Route Quote first when the question is whether the next paid tool call is worth buying.
OpenAPI x402 manifest Product card llms.txt
  • Agent Route Quote $0.03 · Estimate the lowest-cost sensible agent execution lane before buying model calls or xpay tools. Returns a budget decision, tool-stack recommendation, and fallback plan.
  • Public Lead Brief $0.03 · Fetch a public website and return a buyer-fit brief with public signals, agentic offer angles, and next actions. No private contact database is queried.
  • DeFi Token Risk Snapshot $0.01 · Return a research-only token risk snapshot from public liquidity, volume, pair-age, volatility, and data availability. Does not trade and is not financial advice.
  • Market Tool Comparison $0.03 · Compare a task against public xpay catalog options and observed high-demand tool patterns before an agent chains several paid tools. Returns competing tool surfaces, Signal Desk countermoves, moat guidance, unsupported claims, and recommended next paid calls.

Signal Desk returns planning and public-data intelligence only. It does not execute model calls, send outreach, buy/sell tokens, provide financial advice, or prove downstream revenue.
