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. Three things most paid search tools do not do: it runs on more than one search provider and fails over between them, so a dead upstream costs you a retry rather than an answer; it never charges you for a search that did not come back, returning the fee as credit instead; and every answer carries a DSSE-signed receipt naming the provider that actually served it, over your question and the results, so what your agent retrieved can be proven later. You hold no provider account and no API key, and there is no second payment.","tags":["web-search","search","google","serp","web","research","x402","one-payment","signed-receipt","agent-commerce"],"examples":[],"inputModes":[],"outputModes":[]},{"id":"ghost_schema_freshness","name":"schema freshness","description":"Has this published JSON Schema or OpenAPI document changed since a fingerprint you hold?

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.
