Atlas Cloud's Coding Plan packages the best open-source LLMs into flat-rate subscriptions designed for coding agents and AI-assisted development. It cuts your spend on vibe coding and agent calls dramatically while giving you the freedom to switch between models without juggling separate billing.

Why Coding Plan

• Top open-source models, one plan. Use GLM, MiniMax, Kimi, DeepSeek and more from a single subscription. New models are added continuously.
• Lower effective cost than OpenRouter. Once converted through credits, the plans land at roughly 45%–65% of the underlying model price — among the most competitive on the market.
• Works with the tools you already use. First-class support for Codex, Claude Code, OpenClaw, Cursor, Trae, OpenCode, and more, plus raw API access for anything else.

Plan Types

Two plan formats are available. Choose either or combine them.

Deduction Order

When you have credits from multiple sources, they are consumed in this order:

1. If you hold both a Monthly Subscription and a Pay-As-You-Go pack, the subscription's daily allowance is used first. Once the daily cap is reached, deductions roll over to the pay-as-you-go balance.
2. If you hold multiple Pay-As-You-Go packs, the pack with the earliest expiry is consumed first.

Where to Buy

Manage and purchase plans at atlascloud.ai/console/coding-plan.

Heads up: New purchases and renewals are settled through Stripe only. Account balance and promotional credit cannot be used to pay for Coding Plan.

Supported Models & Credit Rules

Coding Plan meters usage in credits, with a fixed multiplier between tokens and credits.

Credit consumption = input_tokens × input_multiplier + output_tokens × output_multiplier

Per-model multipliers are listed on the plan page and update as new models join. The console always shows the current, authoritative table.

Monthly Subscription Renewal Rules

• Repurchase the same tier while your plan is still active and the validity period is extended by another 30 days — your remaining time is preserved.
• Upgrade mid-cycle and you only pay the prorated difference between the two tiers, based on how many days remain on the current plan.

Example

A Starter plan is purchased on April 28 (valid through May 28). On May 14, the user upgrades to Lite.

• New validity: still May 28 (the original expiry).
• Prorated upgrade fee: ($20 − $10) × (14 / 30) = $4.67.

API Access & Client Setup

Calling the API Directly

Coding Plan traffic flows through a dedicated API key that is separate from your standard Atlas Cloud key.

• Base URL: https://api.atlascloud.ai/v1
• API Key: Generate one from Plan Management → Get API Key.

Request and response shapes follow the OpenAI-compatible specification — see Model APIs for full examples.

Client Configuration

Most coding tools (OpenClaw, Hermes, OpenCode, Cursor, Copilot, …) take an OpenAI-compatible endpoint:

https://api.atlascloud.ai/v1

Claude Code, which speaks the Anthropic Messages protocol, points at:

https://api.atlascloud.ai

The sections below walk through the most common tools.

Claude Code

Configure environment variables

Important: replace ANTHROPIC_AUTH_TOKEN below with the API key you generated on the Atlas Cloud console.

Settings file location:

• Windows: %USERPROFILE%\.claude\settings.json
• macOS / Linux: ~/.claude/settings.json

Edit settings.json and set the API key and the model you want to route through:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "atlas-api-key",
    "ANTHROPIC_BASE_URL": "https://api.atlascloud.ai",
    "ANTHROPIC_MODEL": "zai-org/glm-5.1",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "zai-org/glm-5.1",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "zai-org/glm-5.1",
    "CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS": "1"
  }
}

OpenClaw

1. Run the OpenClaw onboarding wizard

After installation, open your terminal (SSH / CMD / Terminal) and launch the wizard:

openclaw onboard

Select Yes → QuickStart → Custom Provider, then:

1. Enter the API Base URL: https://api.atlascloud.ai/v1
2. Paste your Atlas Cloud API key.
3. Paste the model ID. Choose the OpenAI-compatible protocol.
4. Verify the connection — you should see Verification successful.
5. Give the endpoint a custom ID and display name.

2. Or configure the settings file directly

• macOS / Linux: ~/.claude/settings.json

{
  "baseUrl": "https://api.atlascloud.ai/v1",
  "apiKey": "your-atlas-key",
  "api": "openai-completions",
  "models": [
    {
      "id": "zai-org/glm-5.1",
      "name": "zai-org/glm-5.1",
      "contextWindow": 200000,
      "input": ["text"]
    }
  ]
}

Trae

In Trae, add a custom OpenAI-compatible provider with the Atlas Cloud base URL and your Coding Plan API key.

Cursor

In Cursor → Settings → Models, add a custom OpenAI-compatible model pointing at https://api.atlascloud.ai/v1.

OpenCode

Open the OpenCode config file opencode.json:

• Linux: ~/.config/opencode/opencode.json
• Windows: %USERPROFILE%\.config\opencode\opencode.json

Provider config

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "atlascloud": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "atlascloud",
      "options": {
        "baseURL": "https://api.atlascloud.ai/v1",
        "apiKey": "your-atlas-api-key"
      },
      "models": {
        "zai-org/glm-5.1": {
          "name": "glm-5.1"
        }
      }
    }
  }
}

Codex

1. Register the provider

On macOS or Linux, create ~/.codex/config.toml:

model_provider = "atlas_coding_plan"
model = "zai-org/glm-5.1"

[model_providers.atlas_coding_plan]
name = "atlascloud"
base_url = "https://api.atlascloud.ai/v1"
wire_api = "chat"
requires_openai_auth = true

2. Add your API key

Create ~/.codex/auth.json:

{
  "OPENAI_API_KEY": "atlas-api-key"
}

Replace atlas-api-key with the key you generated on the Atlas Cloud console.

3. Start Codex

Skip the update prompt and you're ready to go.
