Add Alibaba Cloud Model Studio Coding Plan provider

Provider Name

Alibaba Cloud Model Studio — Coding Plan

Provider Website

https://modelstudio.alibabacloud.com/

What usage data does this provider expose?

Alibaba Cloud's Coding Plan is a flat-rate monthly subscription for AI coding tools. It gives API access to multiple models under one key, with rate limits tracked as request counts (not tokens).

Subscription tiers (USD):

	Lite	Pro
First month	$3	$15
2nd month (50% off)	$5	$25
3rd month onward	$10/mo	$50/mo
Requests / 5 hours	1,200	6,000
Requests / week	9,000	45,000
Requests / month	18,000	90,000

Included models (8 total):

• Qwen: qwen3.5-plus (vision), qwen3-max-2026-01-23, qwen3-coder-next, qwen3-coder-plus
• Zhipu: glm-5, glm-4.7
• Kimi: kimi-k2.5 (vision)
• MiniMax: MiniMax-M2.5

Deployment modes:

• International — endpoint in Singapore, compute worldwide excl. China
• Global — endpoint in US (Virginia), compute worldwide

Base URLs:

• OpenAI-compatible: https://coding-intl.dashscope.aliyuncs.com/v1
• Anthropic-compatible: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic

Usage data is exposed via the console at modelstudio.console.alibabacloud.com with 3 gauges: last 5 hours, last 7 days, last 30 days (percentage-based). An API endpoint likely exists similar to MiniMax's /v1/api/openplatform/coding_plan/remains pattern (see issue #222).

Will you build the plugin?

Yes, will build the plugin within a day or two.

Additional Context

This is notable because it bundles 8 models from 4 vendors under one subscription at very low cost. It explicitly supports Claude Code and OpenClaw as client tools. The plan is non-refundable and restricted to interactive coding tool use only (no batch/automated calls).

The existing MiniMax issues (#222, #165) are related but cover MiniMax as a standalone provider — this would track Alibaba's multi-model Coding Plan as its own provider.

Super cool that you're bringing this up because I just subscribed to it as well, as a test, and I was immediately wondering if they have an API to expose their limits. Thank you so much for looking into it. I appreciate it!

I'm also testing that, in fact building the plugin as a test for qwen3-max in Claude Code

Unfortunately, we are blocked.

The Reality

1. Plan-specific API keys (sk-sp-...) only work for:
   - Making model calls (messages/completions)
   - NOT for quota/usage tracking endpoints
2. The Coding Plan usage API is SESSION-ONLY
   - Requires web login cookies
   - No API key authentication available
   - This is intentional by Alibaba Cloud (security measure)
3. No alternative API endpoint exists for plan-specific keys to access quotas

Conclusion

There is NO way to integrate the Alibaba Coding usage API with just an API key. The architecture requires:

• ✅ Model calls: API key authentication (sk-sp-...)
• ❌ Usage quotas: Session cookie authentication ONLY

[pbuchman]

Also: there is not way to use oAuth app to access Coding Plan. The only way is via cookie-auth-based-endpoint. Unfortunately.
Cookie is very very short living, they say 24h but I got logged out a couple of times over past hours, not worth publishing in the app.

Also # 2: I thought about ccusage for this, but it does not make sense - we'd have to support each tool, not the provider.

Long story short: we have to wait unless / if they externalize their api and allow to access that with coding plan API key (note: api key is diffrent for metered usage vs. subscription to coding plan)

[pbuchman]

One more option to consider - running qwen code to manage subscription - have to investigate this option

edit: nope, also uses key

[robinebers]

That's a bummer, but we'll leave it open because maybe they will be away soon.
