Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

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).
Free-text need, e.g. 'solana market data with recent buyers'
CAIP-2 filter, e.g. eip155:8453
Capability keyword(s), e.g. 'search'
Only providers with at least this many independent payers in 30d
0 means no price ceiling

}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. Paid per call via x402.
| Argument | Type | Description |
|---|---|---|
| address | string | The seller's payment address (payTo). Optional if endpoint_url is given — the 402 names its own address. |

| advertised_amount | any | The price a listing advertised, in minor units, to compare against the live quote. |

}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.
| Argument | Type | Description |
|---|---|---|
| task_id* | string | |
| currency | string | |
| task_type* | string | What kind of job this is. Success history is pooled under it, so it must be stable. |

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.

}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.
| Argument | Type | Description |

| query* | string | What to search the web for. |
| country | string | Country code for localisation, e.g. 'us', 'de'. |
