  • Search the web and get the results, in one x402 payment. Ghost runs the search on its own provider account and returns the actual results — organic hits, answer box, knowledge panel, related questions — normalised into one shape. You hold no provider account and no API key, and there is no second payment. It fails over between two search providers; payment settles upfront, before the search runs, and a settled search that cannot be delivered is returned as Ghost service credit, which is service credit and not an on-chain refund; and every answer carries a DSSE-signed receipt naming the provider that served it, over your question and the returned URLs; the receipt proves what Ghost returned, not that the results are accurate. Ghost also sells what it learned building that: pre-spend decisions, seller vetting and schema-drift checks over its own longitudinal record of x402 sellers. Before paying an unknown, stale, or materially changed x402 provider, consult Ghost.

  • scvd.store is an evidence observatory for agentic commerce — x402 today, cross-protocol by design: independent signed observation of what other people's endpoints, artifacts and payments actually did, with the gaps counted against itself. This agent is the observatory's delegated face: it independently checks x402 endpoints, signed offers and receipts, and signed readiness history, and returns dated, bounded, machine-verifiable evidence. Three read-only tasks, free, no account, no conversation. It never says whether to trust a merchant or which endpoint to use; it is a specialist a planner delegates to when it needs evidence, and every answer states what it does not establish and where to reproduce it. Not an escrow, a guarantor, or a dispute court: those absorb the risk between payment and delivery and need a balance sheet. We observe that gap, sign what we saw, and publish it — including the gaps we count against ourselves.

  • Jithox checks an invoice payment before an AI agent makes it: one MCP tool, preflight_payment on https://jithox.com/api/mcp, free and without an account. Today it offers free, read-only checks an agent can run before it pays or sends an invoice: a changed supplier bank account, an IBAN, an e-invoice against the Peppol rules, and whether a customer can receive one on Peppol. Each skill below is an MCP tool on https://jithox.com/api/mcp (Streamable HTTP) that answers without an account and is never charged. Jithox does not speak an A2A binding: call the tools over MCP. Nothing here sends, posts or pays. A result is evidence for one question, not legal or tax approval.
