    System Notice

    Important Reminder

    ✅0.25 USD recharge per dollar (approximately 1/4 of the official 1 per dollar)

    ✅Cheap AI API comprehensive resource station, website: http://cheapaiapi.store

    ✅The website has an online invoicing system. After recharging, you can directly apply to issue ordinary invoices to companies (including schools); the "Consumption List" function has been launched, and you can query and download consumption records for a certain period of time in "Personal Center" - "Consumption List".

    ✅We welcome large-scale customization by enterprises and universities. If you need to sign a contract, make a corporate transfer, issue a special invoice, etc., please scan and add the company's WeChat account in advance through "Contact Us" above

    ✅If you have any questions, please read the tutorial and code calling document first: https://cheapaiapi.apidog.io/

    ✅The website "Notices" will only publish Important Reminder information to help users make better use of the "Transfer Platform". For model updates, please check the "System Announcement".

    🌟 General Model Guidelines:

    ✅1. Please choose to be compatible with 0penAI specifications

    ✅2. Correctly fill in the interface URL address (under Openai compatibility specifications): https://api.cheapaiapi.store Or: https://api.cheapaiapi.store/v1 or routing request address: https://api.cheapaiapi.store/v1/chat/completions Different applications may require different address URLs, please try one by one.

    ✅3. Fill in your key correctly, usually a string of "sk-*****". You can find it in the API token and edit your key, set the limit or add groups, etc. Please keep your key properly to avoid loss.

    ✅4. Fill in the model name correctly: You can directly copy the model name you want to use in the model list, 300+ model name list and price: https://cheapaiapi.store/modelhub

    ✅More calling methods: For various application software, python and other code calls, and special model calling methods, please refer to the document tutorial: https://cheapaiapi.apidog.io/; Even if you don’t understand code, you can tell the big model (such as claude’s latest model) our documents and your needs, and let him help you output the correct calling code

    🌟 Group Usage Reminders:

    ✅When using the Gemini model, please add the key to "High Quality Gemini Group"

    ✅When using claude code, please add the first key group as the claude code exclusive group

    ✅Limited-time special offer group will be discounted by 40% off the current price. It supports most models in Gemini, Qianwen, deepseek, Doubao, etc. When using these models, you can add the "limited-time special offer" group in the key as the first one

    ✅ Pay special attention when using different models, please check the group this model is in, and adjust the key to the corresponding group. Models in different groups come from different channels and have different magnifications. The price is the price of the default group multiplied by the magnification of the current group.

    ✅Models are constantly updated and changing following the official website, please pay attention to the 300+ model list and prices https://cheapaiapi.store/modelhub

    ✅ It is recommended to add multiple groups in the key, with the magnifications arranged from low to high, to avoid channel saturation or network fluctuations and inability to output, and to ensure the reliability of the call.

    ✅ If you have code problems during the code calling process, you can throw our documents and your requirements to claude4 or gemini2.5pro (can be called directly online in your console - training ground) and let them output the correct code for you.

    🌟 Notices

    ✅ In order to better serve customers using the claude model, we will create a new Claude Code exclusive group (1.5 times). The pure az group will not be fully compatible with Claude Code. Users who use Claude Code should switch to the Claude Code exclusive group in time. Thank you for your support!!

    ✅At the same time, the website "Notices" will only publish Important Reminder information to help users make better use of the "Transfer Platform". For model updates, please check the "System Announcement".
