    Server tool list (10)

    Raw names from tools/list. Only developers need these.

    find_serviceOptional demand-feedback route. Describe one authorized sanitized business need once. Zinvyl returns the best fixed-scope offer and next purchase action, or records an unsupported need as privacy-minimized product telemetry. For read-only matching, start with qualify_task.
    list_offersUse when comparing Zinvyl's full eight-offer catalog. For a single sanitized need, start with read-only qualify_task. Returns price, delivery window, required inputs, exclusions, and direct intake URL; use get_acceptance_tests only after selecting an offer.
    get_purchase_requirementsUse after selecting an offer. Returns the exact price, five-field buy_service contract, delegated-authority requirements, machine-payment route, capacity limits, and authoritative funding rule without creating an intent.
    buy_matching_serviceOne-call path for a buyer agent that has explicit delegated authority for a stated allowlist of exact Zinvyl offers. Zinvyl matches one sanitized outcome and creates a bounded purchase intent only when the matched offer is allowlisted and its exact fee fits the delegated ceiling. A catalog gap or authority mismatch creates no order or payment claim.
    buy_serviceFive-field, retry-safe agent purchase path. Creates one bounded intent only when delegated authority covers the exact fee. Reusing buyer.request_id for an unchanged purchase returns the same intent. Returns Stripe MPP plus a direct human approval fallback and never claims payment before ledger verification.
    create_purchase_intentCompatibility alias for existing clients; new integrations should use buy_service. Use only after selecting one offer when the calling agent has explicit delegated authority for that exact fixed fee. Creates the governed purchase intent and quote, then returns the no-human Stripe MPP route plus a human Checkout fallback. It does not itself claim payment or start work.
    qualify_taskUse when a buyer's sanitized problem is not yet mapped to an offer. Returns one fixed offer ID, a broader-service route, or a scope-reduction decision; it performs no diagnosis and creates no order.
    match_or_capture_demandCompatibility alias for existing clients; new integrations should use qualify_task first and find_service only after consent. Returns an existing fixed offer when one matches. Otherwise records privacy-minimized product-demand telemetry for owner review; it creates no order, quote, outreach, funding claim, or delivery commitment.
    get_acceptance_testsUse after qualify_task or list_offers identifies an offer and detailed scope review is useful. Returns the exact delivery acceptance tests, exclusions, and evidence boundaries that limit what Zinvyl may claim for that offer.
    prepare_purchase_routeCompatibility inspection alias for existing clients; new integrations should use get_purchase_requirements and buy_service. Use only after selecting an offer and confirming explicit purchasing authority. Returns the purchase-intent schema and payment-route API endpoint; it does not create, fund, verify, or start an order.
