What CoderPlan does

CoderPlan is a developer-focused API relay and model access service for tools such as Claude Code, Cursor, Codex CLI, and Gemini CLI. The site describes it as a way to use model APIs with usage-based billing, rather than paying a fixed monthly fee in advance.

It positions itself around real-call accounting: after each request, users can review the model used, token counts, cache reuse, savings, and the resulting credit change. The service also publishes setup documentation for connecting common coding tools and recommends running a small verification request before moving to normal work.

Core capabilities

Tool-specific integration guides

Supports developer workflows around Claude Code, Cursor, Codex CLI, and Gemini CLI with tool-specific setup instructions.

Usage-based billing

Uses actual API usage to deduct credit, so spending follows real requests instead of a flat monthly fee.

Per-request usage accounting

Shows model, tokens, cache reuse, savings, and credit changes after each call so users can inspect what a request consumed.

Cache-aware request handling

Supports caching optimization, with the site explaining that repeated context can be reused to reduce cost on long-context tasks.

Multi-model coverage

Offers a range of models from providers such as OpenAI, Anthropic, Google, DeepSeek, Zhipu, Alibaba, Moonshot, MiniMax, Mimo, and Tencent, with pricing listed on the site.

Rechargeable credit balance

Provides API usage credit top-ups that do not expire, letting users add credit when needed rather than prepaying a month-long subscription.

Common ways to use CoderPlan

Connect Claude Code for coding tasks
Set up Claude Code with CoderPlan by pointing `ANTHROPIC_BASE_URL` to the CoderPlan endpoint and using the CoderPlan key in `ANTHROPIC_AUTH_TOKEN`, then run a short task to confirm the connection.
Use CoderPlan inside Cursor
Add CoderPlan as an OpenAI Compatible Provider in Cursor, set the `/v1` Base URL, and verify the configuration with a small request before using it for editing, explanation, or refactoring work.
Route Codex CLI requests through CoderPlan
Configure Codex CLI with the documented `/v1` Base URL and API Key so it can run project tasks through the same usage-based account balance.
Connect Gemini CLI to tracked model usage
Set up Gemini CLI with the documented API Key, model, and `GOOGLE_GEMINI_BASE_URL` fields to use Google model access with usage tracking and billing details.
Verify access before production use
Start with a low-risk prompt or short function explanation to confirm authentication, quota, and model access before moving to larger coding work.

Pros and Cons

Pros

Designed for developer workflows that use Claude Code, Cursor, Codex CLI, and Gemini CLI.
Charges by actual API consumption instead of a fixed monthly subscription.
Exposes request-level details such as model, tokens, cache reuse, savings, and credit changes.
Publishes model pricing and setup guidance directly on the site.
Offers non-expiring usage credit top-ups for flexible budget management.

Cons

Setup is tool-specific, so each client follows its own endpoint and key fields instead of a single universal configuration.
The site recommends a test call before real work, which implies initial setup and model selection may take some validation.
Some model entries on the pricing page are marked as coming soon, so coverage is not identical across every listed family.

FAQ

How do I get started with CoderPlan?

CoderPlan provides setup guides for Claude Code, Cursor, Codex CLI, and Gemini CLI. The quick-start doc recommends creating an account, adding API usage credit, creating an API Key, then following the tool-specific tutorial and sending a short test request to confirm authentication, quota, and model access.

How is Cursor connected to CoderPlan?

For Cursor, the docs say to add CoderPlan as an OpenAI Compatible Provider and use the CoderPlan `/v1` Base URL plus your API Key. The guide recommends testing with a small request first, such as asking Cursor to explain a short function.

How is Claude Code connected to CoderPlan?

For Claude Code, the docs say to point `ANTHROPIC_BASE_URL` to the CoderPlan endpoint and place the CoderPlan `sk-` key in `ANTHROPIC_AUTH_TOKEN`. The guide also says not to append `/v1` to that endpoint in Claude Code.

How does usage tracking and billing work?

The site says CoderPlan charges by actual API usage and records model, tokens, cache savings, and credit changes for each request. The pricing and setup pages also say the service uses caching and routing efficiency to reduce cost, rather than replacing requests with cheaper models.

Who is CoderPlan best suited for?

The docs and pricing pages indicate the platform is aimed at developers using AI coding tools such as Claude Code, Cursor, Codex CLI, and Gemini CLI. The copy emphasizes starting with a small task first so you can verify model access and request behavior before committing to larger work.
