Pricing
These are the public prepaid subscription prices for ChainFuel, an OpenAI-compatible API gateway. You pay for a software subscription and a usage quota. You are not buying a license from OpenAI, Anthropic, or xAI.
The amount and the term are shown again before you pay. A 1-month plan is 30 days, except small-spark, which is 5 days. Where a plan offers 3 months, the price is 85% of 3 × the monthly price. Where a plan offers 6 months, the price is 80% of 6 × the monthly price. A dash means that term is not offered.
Prices below are CNY list prices from the public catalog on 2026-11-12. The checkout amount controls if the catalog changes.

What the allowance means
The day / week / period figures are usage quotas inside the subscription, not a second price. Unused quota does not convert to cash.
Model unit prices
Per-model rates for metered use are published at chainfuel.tap365.org/models. That page is separate from these subscription prices.
Balance top-up
The existing site also sells account balance from ¥20. That top-up is not one of the subscription rows above. A limited recharge bonus may apply on that site until 2027-10-07. The bonus is not part of the subscription price in this table.
订阅价格
上表是 2026-11-12 公开目录里的预付费订阅标价，单位人民币。季付为月价 ×3 ×85%，半年付为月价 ×6 ×80%，目录未开放的周期标为「—」。用量额度不是第二套售价。付款前以结算页展示的金额和周期为准。
