API relay credit
Redeem at · jc.jichuanai.com
Code sent after paymentThe code is issued as soon as payment clears. It does not expire.
How it billsOne credit is one US dollar of list price, and ¥1 buys one credit. You pay list price × the group multiplier — the multiplier is the discount. Billing is per token, nothing accrues while idle, and the model catalogue shows the list price beside every tier, one row per model.Full rule ↓

How to use it
Order and pay, get the code
The code is issued as soon as payment clears — on the order page, and in the email.
Register at jc.jichuanai.com/register
Free. Registering does not grant any credit; it just gives you an account to hold it.
Sign in, open /redeem, paste the code
The credit lands immediately. If you are not signed in it bounces you to the login page — that is expected.
Create an API key at /keys
That key is yours. Do not hand it to anyone.
Point your client at the endpoint
The endpoint is jc.jichuanai.com/v1, OpenAI-compatible — Cherry Studio, Cursor, any SDK. The key page prints the address too; trust that one.
What the number means
What you pay is what lands — we take no cut. Models bill per token: you pay for what you call, and nothing while idle. Per-million-token prices for every model (input and output are priced separately) are listed on the relay model catalogue — visible once you register, which is free, without topping up first. Buy the smallest tier, run it for two days, then decide from your own bill.
- One credit = one US dollar of list price
- ¥1 buys one credit, and a credit covers one dollar of the vendor’s own list price — that is where the saving comes from. A credit is not a yuan; do not estimate your runway in yuan.
- You pay = list price × group multiplier
- The multiplier is the discount: 0.18 means 18% of list. Each model group has its own, and the model catalogue shows the list price beside every tier, one row per model — visible once you register, which is free, without topping up first.
When not to buy this
- You want the ChatGPT or Claude web chat interface — credit cannot give you that. Credit is API-only: Claude Code, Cherry Studio, Cursor, your own scripts. For the web app, see official top-ups.
- Credit buys model calls and is not refundable to cash. Buy the smallest tier first, confirm the model you need runs and is fast enough, then consider a larger one.
Common questions
Is this a subscription? Does it bill monthly?
No. It is credit, not a plan. One top-up is one top-up — nothing recurs, and nothing is charged while you are not calling the API.
Do I have to register before redeeming?
Yes. The code adds money to an account, so the account has to exist first. Registration is free and grants no credit by itself.
Which models can I call?
GPT, Claude, Gemini, Grok and around twenty Chinese models. The full list and the per-million-token price for each are on the relay model catalogue — you can read it as soon as you register, before topping up.
Can I cash the credit back out?
No. Credit buys model calls only. That is why we suggest starting at the smallest tier.
Does an unredeemed code expire?
No. Redeem it whenever. Once redeemed the credit sits in your account, so look after the account.
The relay site is in English. Is that the right site?
It is the right site. jc.jichuanai.com is our own relay; its interface is English-only today. The redeem page and the key page are the two you need, and both are linked above.

If what you actually want is a chat window in a browser, that is the other route.
