What is Agent.Space?

Model plans + a cloud Agent Workspace

Agent.Space has two parts: dependable model capacity and a persistent place where that capacity becomes finished work.

01UP TO 50% OFF

Model plans

A simpler way to subscribe to models

One credits balance for every model: pay-as-you-go channels need no purchase and charge credits as you call, and plans save more on the models you use most. Plans, credits, billing and Model API Keys stay in one place.

02ALWAYS ONMULTI-DEVICE

Cloud Agent Workspace

An always-on Workspace for Agents

Codex, Claude Code, and other Agents keep running in the cloud. Sessions, files, previews, and team context remain together so work can continue at any time.

Explore the Workspace

01 / Model pricing

Recommended plans and pay-as-you-go

One credits balance for every model: pay-as-you-go channels need no purchase and charge credits as you call, and plans save more on the models you use most. 1 credit = US$1.

  1. Add credits

    Top-up credits never expire, or start a credit subscription that tops up every month. 1 credit = US$1.

  2. Pay as you go

    Every pay-as-you-go channel is ready to use with no purchase. Calls are charged to credits by the tokens actually used.

  3. Save with a plan

    Subscribe to a plan for the models you use most. Its allowance goes first; once it runs out, or for models outside the plan, calls switch to pay-as-you-go automatically.

  • Allowance stays isolated

    The platform keeps allowance and access boundaries separate.

  • 7-day cycles, clear rules

    Allowance resets in full every 7 days. Unused allowance does not roll over.

02 / Developer API

Use Agent.Space plans and credits in any Agent product

Codex Dedicated plans cover OpenAI models, and credits pay for other available models as you go. Use them in Agent.Space, Codex, Claude Code, OpenCode, Hermes, and other Agent products you already work with.

03 / Agent clients

Why connect through Agent.Space

  • One key

    One API key, many model providers

    OpenAI, Anthropic, DeepSeek, and more share a single key and endpoint. Switch models without switching accounts.

  • Two protocols

    OpenAI Responses and Anthropic Messages

    Connect over each client's native protocol. No proxies and no client patches: configure once and keep working.

  • Clear billing

    Plans and credits stay separate

    Models in your plan use its allowance first, the rest is paid from credits, and every request is visible in Request history.

  • Your choice

    Swap clients any time

    Codex today, Claude Code tomorrow. Your key and allowance stay the same, so your workflow never breaks.

The template already includes the endpoint and selected model. Replace <your-api-key>, then keep the config file local and never commit or share it.

04 / Cloud Workspace

One cloud Workspace for every leading Agent

Codex, Claude Code, and other leading Agents share one cloud Workspace. Files, context, and progress persist so individuals can start immediately and teams can take over at any time.

New chat

Which Agent should we start with?

Multiple Agents and teammates share one Workspace to move real work forward together.

Import local conversations
Codex — describe what you want to build, fix, or review…

Each Session keeps its Agent, files, and context in the same Workspace, so people and Agents can hand work off without starting over.

People and Agents, moving work forward together

01

Multiple Agents move the work forward

Codex, Claude Code, OpenCode, and other Agents can take on separate tasks while sharing the same files and project context.

02

Everyone sees the same working context

Invited teammates can see the same Sessions, files, and progress without repeatedly explaining what has already happened.

03

Change people or Agents without restarting

Context, code, results, and Previews stay in the Workspace, ready for the next teammate or Agent to continue.

04

Work, access, and progress stay clear

Roles, permissions, task status, and usage are visible in one place, so everyone knows who owns the next step.

05 / Security and trust

Your work stays
in your Workspace

Your Workspace is separate from everyone else's. Only people you invite can see its files and tasks.

We use this content only while Agents do the work you ask for—not for advertising.

01

Independent runtime

Every Workspace runs independently

Projects, files, and Sessions run in an isolated Workspace environment, separate from other work.

02

No shared accounts

No account or password exchange

The platform manages service access and resource matching; users never share upstream accounts or login credentials.

03

Team permissions

Only invited members can join

Invite people into the Workspace and control their access with clear roles and permissions.

04

Export anytime

Take your files and results with you

Code, files, and results stay in ordinary directories and standard formats, ready to export when needed.

You control who can access the Workspace, how work runs, and when the project leaves.

06 / FAQ
