Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

payments-polar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Платежи через Polar

Merchant of Record или процессор?

  • Процессор (Stripe) — ты сам отвечаешь за налоги, юрлицо, комплаенс. Часто нужно юрлицо в США.
  • Merchant of Record (Polar) — платформа = продавец записи: берёт на себя налоги/VAT и юрлицо. Работает для фаундеров из любой страны. Меньше боли на старте.

AI Garage использует Polar (MoR).

Подписка или разовая покупка?

  • Подписка — предсказуемый MRR, но нужен постоянный value. Подходит для инструментов регулярного использования.
  • Разовая — проще старт, нет удержания. Подходит для утилит/генераторов «сделал — отдал».

Выбирай по тому, как часто клиент возвращается к ценности.

Поток оплаты

[Купить] на сайте
   │
   ├─► сайт создаёт Checkout Session в Polar → получает ссылку на оплату
   │
   ├─► пользователь платит на странице Polar
   │
   ├─► Polar шлёт webhook payment_succeeded на твой сервер
   │
   └─► сайт открывает доступ к продукту (связка с пользователем Clerk)

Настраивается один раз, дальше работает автоматически.

Интеграция (Next.js)

  1. Аккаунт + организация в Polar, создать продукт и цену.
  2. Поставить SDK, ключи в env: POLAR_ACCESS_TOKEN, POLAR_WEBHOOK_SECRET.
  3. Кнопка «Купить» → Checkout Session → редирект.
  4. Webhook ловит payment_succeeded (и события подписки) → открывает доступ.
  5. Customer Portal из коробки — пользователь сам управляет подпиской.

sandbox → production

Проверь весь цикл в sandbox, затем переключи ключи и URL вебхуков на production. Проверь ещё раз на реальной (тестовой) карте.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
