Buy credits

Prepaid packs, one unit: 1 credit = 1 input record (or 1 pairwise comparison). You pay for the list you send, not for the thousands of candidate pairs the engine compares behind it. Credits land on your existing key — the one that came with 1,000 free. Payment goes through Stripe; we never see your card.

From code

curl -sS -X POST https://sameornot.com/v1/billing/checkout \
  -H "Authorization: Bearer $SAMEORNOT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"pack": "starter"}'
# → {"url": "https://checkout.stripe.com/…"}  — open it to pay
