Decide which x402 provider to pay, before paying it. Consult when the provider is unknown, when a decision you hold has passed its valid_until, or when the price, health, verdict or funding of one materially changed. Finds providers by need and ranks them by real economic evidence: independent payers, calls-per-payer (the repeat signature), last settlement, on-chain trust verdicts and change history. Returns USE/WATCH/AVOID with the exact call, a fallback, valid_until and recheck_when — reuse a held decision until it expires or a trigger fires, rather than asking again. Paid per call via x402; free preflight at /v1/commerce/search/preflight (3/day). Payment: $0.01 USDC on Base per call over x402, settled before the tool runs. An x402 MCP client such as x402-proxy pays it automatically; if you use x402-proxy, set its spend limits first (spendLimitPerTx 0.01, spendLimitDaily 0.10; see /llms.txt). A funded payment and delivery through x402-proxy has not been verified yet.

Before paying an x402 seller you do not know: settlement history, payer structure, funding links, endpoint liveness, quote-vs-advertised price. Use when one named provider or payment address is already in hand and you need a verdict before you pay it. PROCEED/CAUTION/REJECT/INSUFFICIENT_EVIDENCE with a signed receipt. PROCEED means no blocker or concern was found in what Ghost checked. Payability, transfer history, independent demand, seller identity and delivery are reported separately under `evidence`, with anything unresolved listed under `unresolved`; Ghost does not verify who the seller is or that it delivers. Paid per call via x402. Payment: $0.01 USDC on Base per call over x402, settled before the tool runs.

THE PRE-SPEND GATE. Call this immediately before your agent pays an x402/API provider, with the task's own economics. Returns ALLOW / FALLBACK / DECLINE / INSUFFICIENT_EVIDENCE — not advice: a decision your payment path should enforce. It joins the provider's measured record (independent payers, concentration, price drift, reachability, funding links, on-chain verdict) to YOUR numbers (customer_revenue, value_of_success, max_budget, required_margin, failure_cost, switching_cost) and answers the question ranking cannot: is paying for THIS task profitable, and at which provider. Where the task's value is known it maximises expected net value; where it is not, it minimises cost per verified success — which is why it will refuse the cheapest call when a cheaper provider succeeds less often. Unknown economics stay UNKNOWN and are never invented. Report the result afterwards to /v1/gate/outcome (free) — that is the only source of the success rates it uses. Paid per decision via x402, or drawn from prepaid credit. On prepaid credit a cached decision inside valid_until and an INSUFFICIENT_EVIDENCE answer draw nothing. On the per-decision x402 rail an INSUFFICIENT_EVIDENCE question is refused before any terms are quoted, so nothing settles for it; any other decision is paid upfront.

Has this published JSON Schema or OpenAPI document changed since a fingerprint you hold? The schema-drift recheck of the pre-spend policy: run it when a provider's published contract may have moved before you pay it again. Paid per call via x402; DSSE-signed receipt. Payment: $0.01 USDC on Base per call over x402, settled before the tool runs. An x402 MCP client such as x402-proxy pays it automatically; if you use x402-proxy, set its spend limits first (spendLimitPerTx 0.01, spendLimitDaily 0.10; see /llms.txt).

Search the web and get the results, in ONE payment. Ghost runs the search on its own provider account and returns the actual results — organic hits with title, url and snippet, plus answer box, knowledge panel, related questions — normalised into one shape. It fails over from Serping to Serper, so one dead upstream costs a retry. Payment settles before the search runs; if no upstream delivers, the fee becomes Ghost service credit, not an on-chain refund. The DSSE receipt is Ghost's signature over your query, the returned URLs and the provider that served them. It proves what Ghost returned and from which upstream; it does not verify that the results are accurate, complete or current. Search only: Ghost does not fetch the pages. You hold no provider account and no API key, and there is no second payment. Payment: $0.01 USDC on Base per call over x402, settled before the tool runs.
