• search_products read-only

  Search Deer Supply's catalog (Canada). Weight loss: Retatrutide, Tirzepatide and Semaglutide as pre-filled, ready-to-use pens; also recovery products and ancillary capsules. Returns each product with its sizes, today's price in CAD (sales included), price per mg, quantity breaks, stock and links. Call with no arguments to list everything.

  Parameters:

  • query — string — Words to match, e.g. 'tirzepatide', 'mounjaro', 'recovery'.
  • category — string

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

• get_product read-only

  Everything Deer Supply publishes about one product: what it is, sizes and prices, the published dosing schedule, what is in the box, lab (COA) reports, and the related FAQ answers. product_id comes from search_products (e.g. 'retatrutide').

  Parameters:

  • product_id (required) — string

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

• compare_weight_loss_medications read-only

  Side-by-side comparison of the three GLP weight-loss medications Deer Supply sells (Semaglutide, Tirzepatide, Retatrutide): mechanism, generation, the landmark trial's average weight loss, maintenance dose, today's starting price and lowest price per mg in CAD. Use this when someone is choosing a weight-loss option.

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

• estimate_weight_loss read-only

  What the clinical trials averaged for someone at a given starting weight, per medication, at 6, 12 and 18 months, using the same curves as deer.supply/calculator. These are trial averages, not a prediction for any one person.

  Parameters:

  • weight (required) — number — Current body weight.
  • unit — string

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

• quote_cart read-only

  Price a cart exactly as Deer Supply's checkout would: line prices with any sale or quantity break, an optional coupon code, shipping and the total in CAD, plus a delivery estimate when a Canadian postal code is given. variant_id values come from search_products. Nothing is reserved or ordered.

  Parameters:

  • items (required) — array
  • coupon_code — string
  • postal_code — string — Canadian postal code, for the delivery estimate.

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

• create_cart_link read-only

  A deer.supply link that opens the cart with these items already in it, for the person to review and check out themselves (they enter their own delivery details and payment). Agents cannot place orders.

  Parameters:

  • items (required) — array

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

• delivery_estimate read-only

  When an order placed now would ship and arrive, for a Canadian postal code, using the dates Deer quotes on its product pages (orders by noon Eastern ship that weekday; pens travel on the fastest service).

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

  • email (required) — string

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

• get_my_account read-only

  Requires signing in with a Deer account. A plain-language summary of the signed-in customer's Deer account: their name, orders with status and tracking, store credit and rewards, and (when health access was granted) each health profile's weigh-ins, plan and side effects. The same picture the store's own assistant has. Start here.

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

  Requires signing in with a Deer account. The signed-in customer's orders, newest first: number, date, status, total, items, tracking number and expected arrival.

  Parameters:

  • limit — integer

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

• get_my_health read-only

  Requires signing in with a Deer account. Each health profile on the account (one sign-in can chart several people): its id (needed to log anything), recent weigh-ins in pounds and the trend, the treatment plan (medication, week, current dose, next injection, upcoming dose steps), side effects with their ids, reminder settings and the weigh-in reward.

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

• log_weight

  Requires signing in with a Deer account. Record a weigh-in on one of the customer's health profiles. Confirm the number with the person first.

  • entries (required) — array
  • unit — string

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

  Requires signing in with a Deer account. Send a side effect to the customer's care team on one profile. If it sounds severe, tell the person to get medical help right away (call 911 or go to an emergency department) as well; this report is not an emergency channel.
