CloudSigma TaaS Provider for OpenClaw

OpenClaw provider plugin for CloudSigma TaaS — an OpenAI-compatible, multi-model gateway that exposes CloudSigma-hosted model routes through one OpenClaw provider.

This plugin lets OpenClaw use CloudSigma TaaS as a first-class model provider with API-key onboarding, a conservative static model catalog, live model discovery when credentials are available, and OpenAI-compatible request handling.

What this plugin provides

• Provider id: cloudsigma
• Provider alias: cloudsigma-taas
• Default model: cloudsigma/gpt-5.5
• Default endpoint: https://taas.cloudsigma.com/v1
• Auth via CLOUDSIGMA_API_KEY
• OpenAI-compatible chat/completions transport
• Streaming usage support
• Tool-call compatibility through OpenAI-style tool payloads
• Replay/history compatibility for OpenAI-compatible provider families
• Live model discovery from CloudSigma TaaS /models, with safe static fallback
• Conservative image-capability metadata: image support is advertised only for models verified or explicitly marked as vision-capable
• SSRF-safe model discovery restricted to the CloudSigma TaaS host

Install

openclaw plugins install clawhub:@cloudsigma/openclaw-taas-provider

OpenClaw install source:

clawhub:@cloudsigma/openclaw-taas-provider

ClawHub package page:

https://clawhub.ai/plugins/@cloudsigma/openclaw-taas-provider

Source repository:

https://github.com/cloudsigma/openclaw-taas-provider

Requirements

• OpenClaw >=2026.6.6
• A CloudSigma TaaS API key
• Network access to https://taas.cloudsigma.com/v1

Configure

Set the CloudSigma TaaS API key in the OpenClaw runtime environment:

export CLOUDSIGMA_API_KEY=...

Then use CloudSigma models with model refs like:

cloudsigma/gpt-5.5
cloudsigma/claude-sonnet-4.6
cloudsigma/gemini-3.1-flash-lite

The provider alias cloudsigma-taas resolves to the same provider auth as cloudsigma.

Onboarding behavior

During OpenClaw provider setup, the plugin exposes an API-key auth choice:

• Label: CloudSigma TaaS API key
• CLI flag: --cloudsigma-api-key <key>
• Environment variable: CLOUDSIGMA_API_KEY
• Default model: cloudsigma/gpt-5.5

The plugin writes the CloudSigma provider catalog into OpenClaw config and adds a friendly alias named CloudSigma TaaS for the default model.

Static catalog included in the package

The package ships a conservative static catalog so OpenClaw can start even before live model discovery succeeds.

Current seed models include:

Model ref	Capabilities	Context	Max output	Notes
cloudsigma/gpt-5.5	text	400k	128k	Default route
cloudsigma/gpt-5.4	text	1.05M	128k	Large-context GPT route
cloudsigma/claude-fable-5	text	1M	128k	Reasoning-capable Claude route
cloudsigma/claude-opus-4.8	text	200k	32k	High-end Claude route
cloudsigma/claude-sonnet-4.6	text	1M	64k	Balanced Claude route
cloudsigma/gemini-3.1-flash-lite	text, image	1M	65k	Vision-capable Gemini route
cloudsigma/kimi-k2.6	text	262k	262k	Long-output route
cloudsigma/qwen3-vl	text, image	262k	8k	Vision-language route
cloudsigma/pixtral-large	text, image	128k	4k	Vision-language route
cloudsigma/qwen2.5-vl-72b	text, image	32k	8k	Vision-language route
cloudsigma/llama-3.3-70b	text	128k	8k	Open model route
cloudsigma/qwen3-235b	text	256k	8k	Large Qwen route
cloudsigma/glm-4.5-air	text	128k	8k	Lightweight GLM route

Live discovery can supplement this list with additional CloudSigma TaaS chat-capable models when the API key is available.

Model discovery

At runtime, the plugin attempts to fetch CloudSigma TaaS model metadata from:

https://taas.cloudsigma.com/v1/models

Discovery behavior:

1. If no usable API key is present, OpenClaw uses the static catalog.
2. If the endpoint returns an error, malformed JSON, or no usable chat models, OpenClaw uses the static catalog.
3. If discovery succeeds, live models supplement the static catalog.
4. Static seed rows remain authoritative for known model ids, so verified defaults do not drift unexpectedly.

Security notes

• The plugin does not store API keys in the package.
• Authentication is delegated to OpenClaw provider auth via CLOUDSIGMA_API_KEY / setup flow.
• Model discovery uses OpenClaw's SSRF-safe fetch helpers and restricts network access to the configured CloudSigma TaaS hostname.
• The package manifest declares no tools, services, HTTP routes, bundled skills, or background daemons.
• The plugin executes provider registration code only; it does not install native dependencies.

Compatibility metadata

This package declares the OpenClaw compatibility and build contract required for external ClawHub plugins:

{
  "openclaw": {
    "extensions": ["./dist/index.js"],
    "providers": ["cloudsigma"],
    "compat": {
      "pluginApi": ">=2026.6.6",
      "minGatewayVersion": "2026.6.6"
    },
    "build": {
      "openclawVersion": "2026.6.6",
      "pluginSdkVersion": "2026.6.6"
    }
  }
}

Validation and release gates

Before publishing, releases are expected to pass:

npm ci
npm run build
npm test
npx -y [email protected] package validate . --json
npx -y [email protected] package pack . --pack-destination artifacts --json

The test suite covers:

• Plugin registration
• Provider id, alias, auth metadata, and catalog registration
• Onboarding/default-model config writes
• Static catalog shape
• Live discovery success path
• Live discovery fallback on HTTP errors, network failures, malformed JSON, and empty model lists
• Conservative image-capability filtering

Troubleshooting

CLOUDSIGMA_API_KEY is missing

Set the key in the OpenClaw runtime environment and restart/reload the gateway process that loads plugins.

export CLOUDSIGMA_API_KEY=...

A model is missing from the picker

The plugin always ships a static seed catalog. Additional models require live discovery, which needs a valid key and a successful response from https://taas.cloudsigma.com/v1/models.

A vision model is not marked as image-capable

That is intentional unless the route is verified or the CloudSigma TaaS metadata explicitly declares vision/image support. The plugin avoids advertising image input for routes that are only text-safe.

Requests fail with auth errors

Confirm the same environment that runs OpenClaw has CLOUDSIGMA_API_KEY set. Shell-local exports do not help if OpenClaw is running under a service manager with a different environment.
