Tools

• ask_integration ~440 tokens
  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 one provider to anothe
• assess_business ~1641 tokens
  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.

• book_advisory ~290 tokens
  Call this whenever the user asks to speak to a human at Crosswire, or when another tool returns status 'consult'.

• check_coverage ~1274 tokens
  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 capabilities are available ther
• compare_stack_scenarios ~2849 tokens
  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 volume') and returns w
• create_solution_offer ~2167 tokens
  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_indicative_price, then
• design_stack ~1832 tokens
  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 with their dependencie
• fetch ~222 tokens
  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, bps, fee, cost or sa
• get_faq ~615 tokens
  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 over browsing crosswir
• get_indicative_price ~1807 tokens
  Call this whenever any price, rate, bps, fee, spread, cost, discount or comparison is mentioned - before saying any number. THE ONLY PRICING TOOL.

• list_solutions ~426 tokens
  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 per solution, includi
• recommend_stack ~1229 tokens
  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 structured `vertical` + `
• request_offer ~1622 tokens
  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 architecture with more than one
• search ~348 tokens
  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 hand the user. It is the

  Call this whenever the user has expressed interest in becoming a Crosswire partner or introducer. THIRD TERMINAL: the partner programme.
