Getting started

Three steps to your first request

Nothing new to install. Keep the client you already use and switch the API address and key.

  1. 1

    Sign up and top up

    Sign up with email, GitHub or Google; it is free. Then top up in the console with WeChat Pay or a card, from $5. We set up the service for your workspace, and the console shows how far it has got.

    Create an API key

    Create a key for each person or each use, for example one per teammate and one for CI. Each key can have its own concurrency limit and list of models.

Common questions

What is RoamAI?

RoamAI is a Claude API for teams. Create an API key for each person in the console and use it in Claude Code, Claude Desktop or an SDK. There is no monthly fee: usage is charged per token from a prepaid balance, and every request is recorded.

How do I pay?

Sign in and open Top up & billing in the console. Pick $10 / $30 / $100 or enter a whole amount from $5 to $1,000, and pay with WeChat Pay or a card. The balance is counted at ¥1 = $1 of credit, so those amounts add $70 / $210 / $700 of credit. Payment happens on Stripe's page; for WeChat Pay you scan a code there. When you come back to the console, the balance updates within a few seconds. For company bank transfers or invoices, contact us.

Do I need to install anything?

No. Keep using Claude Code, Claude Desktop or your SDK, and replace the API address and key with the ones from the console.

How is it billed?

There is no monthly fee. Usage is charged per token from a prepaid balance, and the price for each model is on the pricing page. Teams with heavy usage can add VIP at $199 or $329 a month: usage is then charged at the lower VIP multiplier, and the VIP fee itself does not include usage.

Can I use a client that only speaks the OpenAI format?

Yes. Add /v1 to the end of the API address and use Chat Completions. Streaming works; tool calls only work in the Anthropic format (/v1/messages).

Can it search the web?

Yes. Include the web_search tool in the request. Searches are charged per search, on top of the tokens.

How many people should share one key?

We suggest one key per person or per use. Usage is counted and keys are revoked one key at a time, so when several people share a key you cannot tell who used what.

What changes in Claude Desktop once it is connected?

It uses a separate set of conversations, so chats from your claude.ai account do not show up there. SSH sessions, cloud environments and Remote Control are not available.

Can I get an invoice?

Yes. We issue invoices and accept company bank transfers. Contact us to arrange it.

Free to sign up, no monthly fee

After you sign up, top up and create a key in the console. We set up the service for you, and you can follow each step there.
