Quote a service call
quote_servicePrice ONE call to a catalog service WITHOUT paying it: it charges nothing, signs nothing and reserves no budget. Pass exactly what you would pass to pay_service (the same slug, path, method, search, headers, body and delegationId): the Router sends that request to the service unpaid, reads the price it asks for, and returns an opaque quoteId, its short expiresAt, the rail (protocol), the network and merchant amount (settlement) and the fee-inclusive total (fee.capChargedCents, whole cents rounded up; fee.capChargedMicros exact, in 1/10,000 of a cent). Unlike the quote on a get_service endpoint (the last merchant price the catalog observed, routing fee excluded), this is priced live for your exact request and includes the fee. Because the request really reaches the service, a service that does not charge for it performs it, so take care quoting a method with side effects; and a quote spends the same per-service rate limit as a payment, so quote once per decision rather than polling. It prices the delegation pay_service would charge (optionSet: "delegation", naming its delegationId), or, with no delegation set up, what a personal crypto delegation would select (optionSet: "deployment"); in that case nextTool is setup_delegation: set one up and quote again before paying, since the delegation you create can select a different rail and price. It checks neither your remaining budget nor your wallet balance (see get_budget and wallet_balance). Next step (nextTool: "pay_service"): if fee.capChargedCents fits what you planned to spend, call pay_service before expiry with the same arguments, the quoted delegationId, quoteId, and maxTotalCents set to that figure as a number. The quote id fixes the exact challenge and fee-inclusive total while maxTotalCents remains an independent ceiling. paymentRequired: false means the service did not ask for payment for this request; upstreamStatus is its answer, and a non-2xx usually means the path, method or body is wrong. The service response itself is never returned. Outcomes, all charging nothing: {"payable":false}, service_not_found, catalog_unavailable and delegation_lookup_failed as in pay_service; quote_unavailable (no quote can be made here and retrying will not change that, so bound the price with pay_service maxTotalCents instead); quote_failed (the Router refused to price the call, or did not answer; see code, message and retryable); credential_refused (re-authorize). FUNDING (funding): chosen as pay_service would choose it. When you hold an active Nevermined Subscription and the endpoint carries a subscription tariff the answer is {"funding":"subscription","credits":…,"tariffVersion":…}: the credits one call costs from the published tariff (the service is not contacted, and there is no quoteId or cent total); then call pay_service with the same arguments. The credits left in your monthly allowance and the price ceiling are checked only when pay_service makes the call, so this answer does not promise the call will be paid with credits. Pass funding: "delegation" to price the delegation instead. Subscription refusals are named as in pay_service. Requires your Nevermined API key on the Authorization header.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| body | No | The request payload you would send; some services price by it. | |
| path | No | The same `path` you would pass to pay_service: read `get_service`'s `requestShape.endpoints[].payServiceArgs.path` and replace every `pathParams` placeholder. Put query parameters in `search`. | |
| slug | Yes | The service slug to quote. | |
| method | No | HTTP method. Omit to use the method the catalog records for the endpoint matching `path` (POST when it records none), exactly as pay_service does. | |
| search | No | Query string without ?, for a slug-routed GET (e.g. flight_iata=AA217). | |
| funding | No | What to price: `subscription` (credits from your Nevermined Subscription) or `delegation` (the fee-inclusive money total). Omit it to price the funding pay_service would use. | |
| headers | No | The extra headers you would send to the vendor. | |
| delegationId | No | The delegation you would pay with, when you authenticate with an API key; defaults to the one pay_service would use. A card or organization-wallet delegation can select a different rail, and so a different price. An OAuth-connected caller is always quoted for the grant it approved, so a value here does not choose the delegation; the result names the one priced. |
