Billing

Each call is priced from the tokens the provider reports, on four separate meters.

Four meters

  • Input, output, cache write and cache read each have their own rate per 1M tokens.
  • Cached input reported by the provider is moved out of input and billed at the cache-read rate.
  • If a successful call reports no usage at all, it is billed as 2,000 input + 2,000 output tokens and marked as an estimate.

Balance and HTTP 402

Pay-as-you-go keys need a balance above zero. A call that finishes as the balance runs out can take it down to −¥1 at most; after that calls answer 402 until you top up.

Monthly plans for heavy agent weeks

Monthly plan metering, step by step

  1. Each call is valued at the official list price in official USD, multiplied by the plan's multiplier, and that amount is drawn from the quota.
  2. Claude plans cover Claude models only; GPT plans cover GPT models only.
  3. A plan is spent through a dedicated key, created automatically at purchase. Pay-as-you-go keys never draw on a plan.
  4. Once the quota or the weekly ceiling is used up, the dedicated key answers HTTP 402. It does not fall back to your balance.
  5. The weekly ceiling resets 7 days after the first draw that follows the previous reset, not on calendar weeks.
  6. Plans stack: every purchase is a separate grant, consumed in order of expiry. Quota left at expiry does not roll over.
  7. Gemini, DeepSeek, Kimi, GLM, Qwen, Grok, MiniMax, Hunyuan and MiMo are metered-only.

Referrals and withdrawals

Direct referrals earn 11% of each payment, the second tier 4%. Withdrawals go to Alipay from $16.67 and are reviewed by hand; earnings can also be moved to your balance.

Refunds

Unused balance from a top-up can be refunded within 8 days of it; the full rules are in the Terms
