pi-provider-qoder

A pi provider extension that connects pi to the Qoder API, exposing Qoder Global and Qoder China models through provider surfaces.

Features

• Two provider entries:
  • qoder — Global / international Qoder.
  • qoder-cn — Qoder China, forced to CN endpoints and independent of QODER_REGION.
• Interactive Login: Global Qoder supports browser device-code flow or Personal Access Token (PAT) login.
• Qoder CN PAT Login: China edition uses a separate PAT login entry (/login qoder-cn) and CN token exchange endpoints.
• WAF Bypass: Built-in WAF obfuscation and body encoding (Encode=1).
• COSY Signing: Full COSY signature header generation (RSA/AES-CBC/MD5).
• Dynamic Model Catalog: Dynamically fetches model limits, effort configurations, and options from the /algo/api/v2/model/list endpoint.
• Reasoning/Thinking Support: Real-time extraction of thinking process from API reasoning or HTML-like <think> tags.

Quick start

Install the provider:

pi install npm:pi-provider-qoder

Or install it globally with npm:

npm install -g pi-provider-qoder

Then log in from pi.

Global / international edition:

/login qoder

China edition:

/login qoder-cn

Personal Access Token (PAT)

A Qoder PAT (pt-...) cannot authenticate API calls directly — the provider exchanges it for a short-lived job token (mirroring the official qodercli / qoderclicn flow) and resolves your account identity automatically.

Global Qoder:

• Run /login qoder and choose Use API Key (PAT), then paste the token.
• Or set QODER_PERSONAL_ACCESS_TOKEN (or QODER_PAT) before starting pi.
• QODER_API_KEY is also accepted; when set, pi automatically exchanges it and logs the provider in during startup.

Qoder China:

• Run /login qoder-cn, then paste the CN PAT.
• Or set QODERCN_PERSONAL_ACCESS_TOKEN (or QODERCN_PAT) before starting pi.
• QODERCN_API_KEY is also accepted and triggers the same automatic startup login.

The exchanged job token is short-lived; the provider transparently re-exchanges the stored PAT when it expires.

Region environment variables

The provider also understands these optional variables:

export QODER_REGION=cn       # or QODER_BACKEND=cn / QODER_MODE=cn

Setting a CN PAT without a global PAT also auto-selects CN mode for the qoder entry, but the recommended explicit China entry is still /login qoder-cn and --provider qoder-cn.

Endpoints

Global:

• PAT exchange: https://openapi.qoder.sh/api/v1/jobToken/exchange
• User info: https://openapi.qoder.sh/api/v1/userinfo
• Usage: https://openapi.qoder.sh/api/v2/quota/usage
• Model / chat gateway: https://api3.qoder.sh/algo/api/v2/...

China:

• PAT exchange: https://openapi.qoder.com.cn/api/v1/jobToken/exchange
• User info: https://openapi.qoder.com.cn/api/v1/userinfo
• Usage: https://openapi.qoder.com.cn/api/v2/quota/usage
• Model / chat gateway: https://gateway.qoder.com.cn/algo/api/v2/...

Models

Global qoder

Exposes the backing model keys returned by Qoder, including:

• Tier Models: auto, ultimate, performance, efficient, lite
• Frontier Models:
  • qmodel (Qwen3.7 Plus)
  • cmodel (Cantus)
  • qmodel_preview (Qwen3.8 Max Preview)
  • qmodel_latest (Qwen3.7 Max)
  • dmodel (DeepSeek V4 Pro)
  • dfmodel (DeepSeek V4 Flash)
  • gm51model (GLM 5.2)
  • kmodel (Kimi K2.7 Code)
  • kmodel_latest (Kimi K3)
  • mmodel (MiniMax M3)

China qoder-cn

The China provider exposes friendly model IDs and maps them back to Qoder CN's internal keys at request time:

| Friendly ID | Qoder CN key | Context | Images | Reasoning | | --- | --- | ---: | :---: | :---: | | auto | auto | 180K | ✅ | ✅ | | qwen3.7-max | qmodel_latest | 1M | ✅ | ✅ | | qwen3.7-plus | qmodel | 1M | ❌ | ✅ | | qwen3.6-flash | q36fmodel | 1M | ❌ | ✅ | | deepseek-v4-pro | dmodel | 1M | ❌ | ✅ | | deepseek-v4-flash | dfmodel | 1M | ❌ | ❌ | | glm-5.2 | gm51model | 200K | ✅ | ✅ | | kimi-k2.6 | kmodel | 256K | ✅ | ✅ | | minimax-m2.7 | mmodel | 200K | ❌ | ❌ |

Compatibility aliases are also accepted for request mapping, such as qwen3.6-plus → qmodel, glm-5.1 → gm51model, and minimax-m3 → mmodel.

Usage

Once logged in, select any Qoder model in pi:

/model qwen3.7-plus

Or start directly:

pi --provider qoder-cn --model qwen3.7-plus

Global example:

pi --provider qoder --model auto
