Important Guidelines

cometapi Getting Started Guide#

How to claim the $0.1 USD credit?#

No special operation required. After registering and logging in, you can see the $0.1 USD credit in your Wallet page.

How to top up? Can I top up without USD?#

1.
After logging in, enter the amount you wish to add on the Wallet page, minimum $10 USD.
2.
Use stripe to complete the payment.

Which large language model APIs are available?#

All supported models and their prices can be viewed on the pricing documentation. All models displayed on the page can be accessed through cometapi.

How to get OpenAI Key, Claude Key, Gemini Key?#

1.
Key refers to token.
2.
After registering and logging into cometapi, go to the "Tokens" menu on the left, and click "Add Token".
3.
Enter a custom token name to generate your Key.
This Key can be used for GPT series models, Claude series models, and Gemini series models.

How to switch between models?#

Change the "model" parameter in your code to switch models.
Note that you need to enter the complete model name. For specific usage methods, refer to the API documentation.


Is billing per usage or monthly?#

1.
Pay-as-you-go: Consistent with official pricing, calculated based on Token consumption. You pay only for what you use.
No monthly subscription required, balance never expires, and unused portions are refundable.
2.
Special model billing: Models like MidJourney, Suno, Luma (image, music, video models) are billed per usage.

Why are there 3 Base URLs? Which one should I use?#

Different development environments or software handle Base URLs differently.
Try these 3 addresses:
https://api.cometapi.com/v1/
https://api.cometapi.com/v1/chat/completions/
https://api.cometapi.com/
If you encounter a 404 error, please check if your Base URL setting is correct.

Does cometapi support Claude opus 4.1 ?#

Yes! cometapi supports the full range of Claude models, including:
Sonnet
Haiku
Opus series

Which URL should I use for Anthropic Claude? What is the Base URL?#

The Base URL is the same for all models:
Including OpenAI, Claude series, Google Gemini, and other models.

How to check how many Tokens were consumed in a call?#

1.
Go to the "Logs" page.
2.
Click on a single log entry to expand detailed call information and view the calculation formula and Token consumption:
Prompt: Understood as the user input.
Completion: Understood as the AI's response.

What do "prompt" and "completion" refer to?#

Prompt: Refers to the content input by the user.
Completion: Refers to the content output by the AI.

What happens if my balance becomes negative?#

When your balance is very low, if the cost of your last call exceeds your remaining balance, your balance will show as negative.
Please top up promptly to continue using the service.
