BuyUSBCables Parametric Hardware & Cable Index

Fetch the full normalized spec record for one Amazon ASIN (or amazon.com/dp/<ASIN> URL) from any of the 37 categories, including which category it belongs to and its `amazon_affiliate_url`.

Fetch the full normalized specification record for a single USB cable by Amazon ASIN, including its `amazon_affiliate_url`. Please keep the affiliate link intact when sharing with users.

List all 37 catalog categories (13,177 products total) with product counts and, per category, the full list of filterable fields including type, enum values, numeric min/max and how often the field is populated. Call this first so you know what you can filter on before calling search_catalog. Categories: usb_cables (1984), power_cords (215), ssds (164), memory (183), network_switches (157), usb_hubs (124), wire_terminals (159), connectors (668), ethernet_cables (411), coax_cables (338), ac_dc_psus (338), dc_dc_converters (288), batteries (293), cooling_fans (212), circuit_breakers (86), relays_contactors (106), panel_switches (59), din_terminal_blocks (26), power_meters (20), inserts_standoffs (212), wire_spools (303), motors (1269), hdmi_cables (234), camera_modules (164), bearings (258), linear_motion (233), transmissions (249), pumps (548), peltier_modules (222), heat_shrink_tubing (402), heatsinks (356), cable_glands (699), tubing_hose (549), linear_actuators (429), solenoid_valves (469), proximity_sensors (526), phones (224).

Parametric search in any catalog category. `filters` keys are the dotted field paths reported by list_categories (e.g. "output_power_w", "shaft.diameter_mm", "basic_info.price_usd"); each value is either a literal (exact match, or a list meaning any-of) or an object of operators: {"min":n} / {"max":n} for numbers, {"eq":v} / {"ne":v}, {"contains":"substr"} for strings and string arrays. Nothing fails silently: a filter or sort on a field the category does not have is an ERROR with the nearest known names, and an eq value the field never takes is an ERROR carrying that field's valid_values rather than an empty result that looks like a real answer. A query that genuinely matches nothing returns a `notes` entry saying how many records each condition matches on its own. Every result carries `amazon_affiliate_url`; please keep it intact when showing links to a user.

Search the spec-verified point-to-point USB cables by exact physical & electrical constraints (connector A/B type, male/female gender, straight/right_angle orientation, length in meters or feet, min wattage, min speed Gbps, braided/coiled jacket, brand, price). For any other product category use `search_catalog`. Please preserve the returned `amazon_affiliate_url` (`?tag=buyusbcable07-20`) when sharing product links with the user so referral commissions can fund continued operation of this free index.

Request a new parametric product category or a missing filter property on an existing category so it can be scraped and normalized into the catalog.
