• search_stores read-only

  Search the UK stores Vouchernaut lists by name or category ("flowers", "Currys", "phone cases"). Each store comes with how many live codes and deals it has, its best few offers with tracked links (each code itself only where the brand has approved AI assistants, else its vouchernaut.com page), a link to shop there and its vouchernaut.com page.

  Parameters:

  • query (required) — string — A store name or what's being bought
  • limit — integer — Stores to return

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_store_offers read-only

  Every live discount code and deal Vouchernaut lists for one UK store, in the order its store page shows them: what each saves, its terms and end date, how many shoppers said it worked or failed, and a link that opens the store with the offer. A code itself comes only where the brand has approved AI assistants; any other comes without it (`code_on_page`), linking to the store's vouchernaut.com page, where the shopper reveals it. The store can be named ("Arena Flowers"), or given by its slug or its vouchernaut.com page. Each link may earn Vouchernaut a commission, which every result discloses.

  Parameters:

  • store (required) — string — The store's name, slug or vouchernaut.com store page URL
  • kind — string — Only codes, only deals, or both

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_products read-only

  Search the products UK stores sell through Vouchernaut (flowers, gifts, hampers, candles, homeware and more): title, store, price, the price after the store's best discount code, honest price-history notes ("Down from", "Lowest in 90 days"), the same product at other stores, and a tracked link to buy. Each product has a `ref` ("<store>/<product>").

  Parameters:

  • query (required) — string — What the shopper wants, e.g. "red roses", "birthday hamper"
  • sort — string — Order: best match (default), cheapest, dearest, newest or biggest price drop
  • type — string — A product type, e.g. flowers, plants, chocolate, food, drinks, candles, beauty, jewellery, cards, balloons, toys, home; children with a dot ("flowers.dried")
  • limit — integer — Products to return
  • store — string — Only this store (its slug, e.g. "arena-flowers")
  • on_sale — boolean — Only products below the store's full price
  • max_price — number — Most it should cost, in pounds
  • min_price — number — Least it should cost, in pounds

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_product read-only

  One product, by its `ref` ("<store>/<product>") or its vouchernaut.com page: every variant's price and stock, the store's best discount code that covers it and the price after it (the code itself only where the brand has approved AI assistants, else the saving and the store page that reveals it), its price history (lowest, typical, now), delivery, the same product at other stores and a tracked link to buy.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• check_deal read-only

  Whether a product's price at a UK shop is a real deal, from Vouchernaut's own record of that shop's prices: pass a product page link from the shop, a barcode, a product's name or a `ref` ("<store>/<product>"). Gives the verdict on today's price (lowest we've recorded, no change, cheaper before and when), the shops selling the same product for less today, and a tracked link to buy. Says plainly when the shop isn't one whose prices are tracked. Never uses shops' own "was" prices or RRPs.

  Parameters:

  • query (required) — string — A product link from the shop, a barcode (8 to 14 digits), a product name ("dairy milk 200g") or a ref

• calculate_take_home_pay read-only

  What a UK employee's pay comes to after income tax, National Insurance (category A), student loan and a workplace pension, for the current tax year, by the year, month and week, with each tax band, the sources and a link to the worked answer on vouchernaut.com. Worked on the year as a whole, as HMRC's rates are; a payslip works each pay period on its own, so it can be a few pounds a year different. Covers England, Wales, Northern Ireland and Scotland and everyday tax codes, not K codes, benefits in kind, other income or the self-employed. Information, not financial advice.

  Parameters:

  • salary (required) — number — Pay before anything comes off, in pounds, for the `per` period
  • per — string — What the salary is per
  • region — string — Where the employee lives for tax: Scotland sets its own bands

• student_loan_repayments read-only

  What a UK student loan costs a month now, and whether it's cleared or written off first: a month-by-month projection to the plan's write-off on stated assumptions (pay rises and RPI, which the caller may change), with this year's threshold and interest rate, the total repaid and the sources. A projection, not a forecast, and information, not financial advice: it never says whether to pay a loan off early.
