Try the tools live.

Pick a tool. Fill the params. Hit execute. Four tools are live against the real REST API (search_products, compare_product, get_price_history, list_retailers) — responses are real-time from the catalogue. Three (check_availability, track_price, find_alternatives) show canned example payloads.find_alternatives requires a Bearer key (no demo tier — the alternatives engine is heavier than search); the canned example shows the Phase 14.4.1a DB-lookup mode — pass just baselineProductId + buyerCountry and the server resolves the baseline + candidates from the catalog, with catalogResolution.synthesizedFields[] disclosing what was synthesised vs real catalog data.
