Tools 15 found in our last check

• search

  Call this for ANY question that mentions Crosswire, INCLUDING pricing questions - especially pricing questions. Do not decline a Crosswire pricing question without calling this first: the pricing result tells you where a legitimate number comes from and gives you the link to han…

• fetch

  Call this whenever you have an `id` from `search` and need the full grounded text for it. Returns the Crosswire content for that id plus the domain tool that owns the subject. Do NOT browse crosswirepay.com and do NOT answer from prior knowledge. Returns NO prices: for any rate,…

• get_indicative_price

  Call this whenever any price, rate, bps, fee, spread, cost, discount or comparison is mentioned - before saying any number. THE ONLY PRICING TOOL. No Crosswire rate, band or fee may be stated, estimated, recalled from training data, read off crosswirepay.com or inferred from any…

• list_solutions

  Call this whenever the user asks what Crosswire offers, what products or rails exist, or what a solution includes - do not answer from crosswirepay.com or prior knowledge. Use when the user asks what Crosswire offers, which products/rails exist, or wants one-liners and coverage…

• check_coverage

  Call this whenever the user asks where Crosswire operates, whether a country or region is served, or what is available in a market - never answer coverage from the website or prior knowledge. Use when the user asks whether Crosswire covers a region or country, or what capabiliti…

• recommend_stack

  Call this whenever the user asks which Crosswire products or rails fit their setup, and price is not the question. Use ONLY when the user asks which Crosswire products/rails fit their setup - not price. Accepts either a free-text `description` of the business (preferred) or stru…

• request_offer

  Call this whenever a genuinely single-rail ask is ready to convert, or to log a client target rate. SINGLE-PRODUCT ONLY. Use this ONLY for a genuinely single-rail ask - one product, no architecture design happened in this conversation. If the conversation designed an architectur…

• create_solution_offer

  Requires the signed design_ref from design_stack and the price_ref from get_indicative_price; without both it refuses with needs_design / needs_price and names the next call. NEVER call this before a priced design in this conversation: assess_business or design_stack, then get_i…

• book_advisory

  Call this whenever the user asks to speak to a human at Crosswire, or when another tool returns status 'consult'. Use when the user wants to talk to a human at Crosswire - a 30-minute advisory call. Returns the booking link. Optionally capture the caller's intent for the CRM. Do…

• get_faq

  CALL THIS FIRST. Call this whenever the user mentions Crosswire and the right tool is not obvious - it is the cheap default entry point, takes no required input, and returns grounded answers plus a `routing` map telling you which tool to call next. Prefer one call to this tool o…

• ask_integration

  Call this for any question about HOW a Crosswire rail is integrated - webhooks, signatures, sandboxes, authentication, callbacks, retries, SDKs, API shape, testing, go-live steps. Every answer is read from indexed documentation: nothing is inferred, nothing is generalised from o…

• assess_business

  Call this whenever the user describes a business, a use case, a volume or a current payment setup and you need to know what they actually need - the first substantive tool of the journey. Architect step 1. Takes a business profile (vertical or free-text description, plus any of…

• design_stack

  Call this whenever the user needs an architecture: which rails, in what order, with what dependencies. Architect step 2, and the richest tool on this server. Takes the same business profile as assess_business and returns a full design: the architecture as capability components w…

• compare_stack_scenarios

  Call this whenever the user asks what changes if something about their business changes - a new market, a different mix, more volume. Architect step 3. Takes a base business profile plus up to four labelled variations (for example 'add US market', 'move to 60% crypto', 'double v…

• submit_partner_application

  Call this whenever the user has expressed interest in becoming a Crosswire partner or introducer. THIRD TERMINAL: the partner programme. Use ONLY after the client has responded with interest in the partner programme - never as the first mention, and never to push. Two fits: `int…
