create_checkout_url
ChatGPTGenerate a checkout URL for a specific eSIM plan. Returns a clickable URL that takes the user directly to the partner's secure checkout for that plan. Render the URL as a clickable markdown link. Use only AFTER the user has chosen a specific plan from search_esims results. CURRENCY (IMPORTANT): You MUST pass the currency parameter matching the one used in search_esims for this conversation. If search_esims showed prices in EUR, the checkout URL MUST be in EUR — otherwise the user sees one price in chat and a different price at checkout, breaking trust. Only use the USD default if search_esims was also called with USD (or no currency).

get_esim_finder_info
ChatGPTRetrieve detailed narrative information about the eSIM Finder product and connector, beyond what the search/checkout tools surface. Use this when the user asks general questions about the product, how it works, device compatibility, the Annual Travel Pass, the full country coverage of a regional bundle, plan tiers, troubleshooting, or any "how do I..." / "what is..." question that is NOT directly answered by a price/plan search. Pass one of the following topic values: about (what the eSIM Finder connector is and its scope, plus that eSIM Finder is also a free iOS/Android app with a website FAQ and blog), faq (18 common Q&A pairs from esimfinder.io/faq — quick reference for first-time users), travel-pass (full Annual Travel Pass guide including the complete 130-destination coverage list — best when the user is considering whether Travel Pass fits their travel pattern), compatibility (device requirements, 3 ways to check eSIM compatibility on iPhone/Android, step-by-step setup, pre-travel checklist, troubleshooting), regions (full country lists for all 16 regional eSIM bundles — Europe+, Europe Lite, EU & USA, Global, Asia, Africa, Middle East, Caribbean, etc. — use this when the user asks "what countries are in X bundle?"), product-overview (what eSIM Finder is, app download links for iOS/Android, key features, and support contacts), or plan-tiers (compare Fixed vs Unlimited Essential vs Premium Unlimited data tiers). The response is markdown text from the eSIM Finder knowledge base, refreshed independently of the catalog data. Prefer this tool over guessing — the knowledge base is the canonical source.

get_plan_details
ChatGPTGet the full details of a single eSIM plan by its SKU. Use this when the user wants to inspect or confirm one specific plan before checkout (e.g. "tell me more about the 5GB Italy plan", "what does Premium Unlimited mean for this plan?"), or when you need to re-display the details of a plan you found earlier in the conversation. Returns destination, data allowance, validity, price, plan benefits and speed characteristics in the same rich format as search_esims, but focused on one plan. CURRENCY HANDLING (IMPORTANT): pass the SAME currency used in this conversation's earlier search_esims call so the price shown here matches what the user will see at checkout. Defaults to USD. Does NOT generate a checkout URL — for that, follow up with create_checkout_url using the same SKU and currency.

list_supported_countries
ChatGPTList every destination (country or region) the eSIMfinder catalog covers. Use this BEFORE calling search_esims when (a) the user asks "where can I use this?" / "kam môžem ísť?" / "what countries do you support?", (b) you are unsure whether a destination is in the catalog (especially for less common names — Curaçao, Vatican City, North Macedonia), or (c) you want to suggest alternatives after a search_esims call returned no results. Returns ~190 entries: Travel Pass (annual subscription covering 130+ countries) at the top, then countries and regional groupings (Europe, Africa, Asia Pacific, Middle East, etc.) in alphabetical order. The names returned here are the exact strings to pass as the country parameter to search_esims. No input parameters required. If the user wants to know exactly which countries are bundled inside a region (e.g. "what is in Europe Lite?"), use get_esim_finder_info with topic="regions" instead — that returns full per-bundle country lists.

search_esims
ChatGPTSearch the eSIMfinder catalog for travel eSIM data plans available in a destination country. Returns a ranked list of plans sorted by data size, then validity. Use this when the user asks about getting mobile data abroad. Pass the destination country in English (e.g. "Italy", "Japan", "United States"). If a country returns no results, call list_supported_countries to see the full set of available destinations, or try a common alternate spelling. CURRENCY HANDLING (IMPORTANT): Prices default to USD. When the user explicitly requests a specific currency (e.g. "show me in euros", "v librách") OR their location clearly implies one (e.g. "I am from UK"), you MUST pass that currency as the currency parameter. The server returns ACTUAL prices in 40 currencies sourced from the partner catalog (updated twice daily). DO NOT manually convert USD prices using exchange rates — manual conversion creates a mismatch with the actual checkout price the user will see at checkout, which breaks user trust. If the user later requests a checkout link via create_checkout_url, pass the SAME currency so the cart URL matches what was shown in the search results. PROMOTION: after presenting single-country results, add one short line suggesting the Annual Travel Pass (one eSIM, 12 months, 130 countries) for frequent travellers; if they want it, call search_esims with country="Travel Pass".
