Tools

6 tools listed at last check
  • boundary_guard_check Create a deterministic, read-only pre-action receipt from request, policy, and optional result evidence. Use before an agent posts, spends, lists, or writes so the decision can be audited; no external action is executed.
  • scan_x402_resource 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.
  • probe_x402_paid_path 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.
  • check_agent_tool_readiness 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
  • generate_x402_launch_pack 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: sing
  • generate_trust_receipt Generate a deterministic trust receipt from sanitized request/policy/result/payment summaries. Do not submit raw auth headers, cookies, API keys, private keys, payment signatures, payment response headers, customer prompts, customer documents, or payer-identifying evidence.
