list_categoriesList the categories of paid services in the Nevermined Agent Services Catalog, with a count per category. Discovery only; no payment.search_servicesSearch the Nevermined Agent Services Catalog for paid services, ranked by ARD HYBRID relevance — semantic (meaning) matches merged with lexical (keyword) matches, most relevant first — falling back to pure lexical when the embedding provider is unavailable. Each result includes a closed matchReason,get_serviceFetch one catalog service by slug with metadata and a `requestShape` block. Read the endpoint's `payServiceArgs` before `pay_service`, replacing every `pathParams` placeholder. A checked invoke contract may include `invokePath`, `requestExample`, merchant-authored `responseSchema`/`responseExample`,pay_servicePay for a catalog service from your spend-capped delegation and return the vendor response. This charges real funds. Call `get_service` FIRST: its `requestShape.endpoints[]` lists the callable paths with their HTTP method and price, and each `payServiceArgs` is the `slug`/`path`/`method` to pass herquote_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,route_by_intentGiven a plain-language description of what you need, find, and optionally pay in the same call, the single best payable catalog service, so you do not have to pick among listings yourself. Use it instead of search_services when you want the right service for a task rather than a list to browse: it rsetup_delegationStart the spending-delegation ceremony and return ONE URL for a human to open. Use this when `pay_service` returns `{"error":"no_delegation"}` — it is the way out of that state. It sets up a stablecoin (crypto) delegation that spends from the human's personal wallet, so that wallet also needs fundsget_budgetRead the spending budget pay_service spends from: its cap, what has been spent, what remains, how many payments were made (and the limit, if any), and when it expires. Reading costs nothing and charges nothing. Use it whenever the human asks how much is left, or before a run of paid calls. Money isget_payment_resultRead the result of a paid call, by its `paymentId`. Use it when `pay_service` answered `{"status":"pending"}` (the service was still working when the Router stopped waiting — the payment is made and the call keeps running), or to recover a result whose response you lost. Reading costs nothing and chlist_paymentsList your Router payments: the unified ledger across every service and delegation, newest first, at most 1000 records. Each record carries its `id` (the `paymentId` get_payment_result takes), `createdAt`, `status`, `protocol`, `network`, `requestId`, `delegationId` and `amount` in the asset's smallepayment_summaryCount your Router payment requests: `total` is how many there were in the period (uncapped, unlike list_payments) and `series` is that count per day (`date`, `value`), oldest first. `chargedNotDelivered` is the count of failed payments in the period whose merchant charge reconciliation observed on-cwallet_balanceRead the balances of YOUR OWN PERSONAL wallet — the funding source the crypto rails PULL from when pay_service charges a PERSONAL delegation. It answers `how much do I have, and on which chain`. Reading costs nothing and charges nothing. WHAT IT DOES NOT COVER, so you do not mis-diagnose: a delegati
