Each API call is billed by actual token usage, matching official pricing. Pay only for what you use. Credits never expire.
Monthly plans include a fixed daily quota (e.g. $50/day on Standard), as low as ¥0.31/USD. Quota refreshes daily and stacks with pay-as-you-go balance.
Spending automatically unlocks VIP tiers with lower multipliers. VIP8 gets a 0.88× rate — the more you use, the less you pay.
One Claude Sonnet 4.6 coding exchange (5,000 input + 2,000 output tokens):
Input: 5,000 ÷ 1,000,000 × $3 = $0.015
Output: 2,000 ÷ 1,000,000 × $15 = $0.030
Total: $0.045 (about ¥0.045, half a cent)
¥1 covers roughly 22 exchanges like this.
