The headless promotions engine for any cart.

Percent, amount, BOGO, threshold gifts, coupon codes, stacking rules — evaluated deterministically against any cart in one API call. Cents-exact, every time.

Quickstart

# 1. Sign up (14-day free trial, no card)
curl -X POST /api/auth/signup -H "Content-Type: application/json" \
  -d '{"email":"you@store.com","password":"s3cure-pass","companyName":"My Store"}'

# 2. Create an API key (JWT from step 1)
curl -X POST /api/keys -H "Authorization: Bearer <jwt>"

# 3. Evaluate a cart
curl -X POST /v1/evaluate -H "Authorization: Bearer sk_pk_..." \
  -H "Content-Type: application/json" \
  -d '{"cart":{"currency":"CAD","codes":["SUMMER20"],
       "lines":[{"id":"1","sku":"latte","qty":2,"unitPrice":450,"tags":["drinks"]}]}}'

Campaign types

Type	Behaviour
percent_off	% off matched lines, largest-remainder cents distribution — line discounts always sum exactly
amount_off	Fixed cents off matched subtotal, distributed proportionally
free_item_on_threshold	Spend ≥ X ⇒ free item (discounted if in cart, reward line if not)
bogo	Buy N of X, get M of Y free — cheapest matching units

Every campaign supports targeting (all | skus | tags), schedule windows, code requirements, stacking flags, priority, and total/per-customer usage limits.
