pricing basis
Group default · multiplier 2
This site prices with a dynamic expression (billing_mode=tiered_expr): price per million tokens = expression coefficient × group multiplier, in site credit units. We always take the default group's first tier (<272000); other groups and long-context tiers are priced differently, and the site's panel is authoritative.

Models it sells and effective prices
Effective = listed price × top-up rate ÷ FX (1.00 CNY / $1 · FX 6.67), i.e. real dollars per million tokens (per call or per second for images and video); the listed price is the site-credit price shown on the panel and can be checked line by line on the site (its page may show a member-group price by default; we use the default group). Reference is the lowest of official and public-market prices; share = effective ÷ reference.

- Which models does 4sapi.com sell, and what do they really cost?
- 截至 2026-11-01，4sapi.com 有 85 个模型有报价。以 Claude Opus 5.5 为例：站方标价每百万输出 $40.00（站内额度），按 1 元 / $1 · Stripe 0 的充值比例和 6.67 的汇率折算，实付 $6.00，是参考价的 30%。
- How is the effective price at 4sapi.com calculated?
- Effective = listed price × top-up rate ÷ FX. 4sapi.com's panel charges 1 CNY per $1.00 of credit; we use the default group. The site's own page may show a member-group price by default.
- Is 4sapi.com reachable right now?
- In the last 24 hours we probed it 45 times: reachable 100%, median time to first byte 1768 ms. Reachability only says whether it can be reached, not model quality.
- Can you still sign up at 4sapi.com?
- Yes. The panel's sign-up endpoint is open (email or human verification may be required).
- How often is this data updated, and how can I verify it?
- Panel prices are fetched daily and reachability is probed hourly; every price on this page can be traced to a fetch snapshot in the evidence drawer. We take no money from measured vendors and make no recommendations.
Want to verify it serves the real model? Run the open-source protocol-consistency check (our probe script or Veridrop) with your own key for that site. We only measure price and reachability; we don't judge for you. Outbound links carry no referral parameters; we only count clicks.
