AxonHub OpenClaw Plugin

AxonHub AI Gateway provider plugin for OpenClaw — Route requests to 100+ LLM providers through a unified API gateway.

Features

• Dynamic model discovery from your AxonHub instance
• Custom base URL for self-hosted AxonHub deployments
• Per-model protocol routing across OpenAI Responses / Chat Completions, Anthropic Messages, and Gemini APIs
• xhigh / max reasoning support for capable model families (OpenAI GPT-5.6, Anthropic Claude Fable 5 / Sonnet 5 / supported Claude 4.x, DeepSeek V4, and Google Gemini 3.x); earlier GPT-5.x / o3 / o4-mini models expose xhigh without max. Other reasoning models fall back to OpenClaw's built-in graceful effort downgrade so unsupported levels do not reach upstream
• Automatic model metadata: context window, pricing, capabilities

Installation

openclaw plugins install @ruelya/axonhub-openclaw-plugin

Or explicitly from ClawHub:

openclaw plugins install clawhub:@ruelya/axonhub-openclaw-plugin

Restart the gateway after installing.

Setup

Run onboarding to configure AxonHub:

openclaw onboard --axonhub-api-key <your-api-key>

Configuration

Onboarding also writes:

{
  "plugins": {
    "entries": {
      "axonhub": {
        "enabled": true,
        "hooks": {
          // Required for the Codex bridge (`before_model_resolve`) on non-bundled plugins
          "allowConversationAccess": true
        },
        "config": {
          "baseUrl": "http://localhost:8090"
        }
      }
    }
  }
}

If you installed the plugin before this was set automatically, add plugins.entries.axonhub.hooks.allowConversationAccess=true (or re-run onboarding / auth setup). Without it OpenClaw blocks the Codex model-projection hook with: before_model_resolve blocked because non-bundled plugins must set ....

Model synchronization

There are three distinct synchronization concerns. They operate independently and should not be confused:

1. AxonHub channel-model sync (server-side). AxonHub itself can refresh the list of models each upstream channel supports about once an hour when a channel has auto_sync_supported_models enabled. This happens entirely inside your AxonHub instance; the plugin neither controls nor replaces it.

2. Plugin instance-cache refresh (client-side). The plugin caches the set of models your API key can currently see (/v1/models on the instance root — never the SPA path /models) with a bounded TTL (default one hour) and a credential-scoped cache. Responses that look like HTML (common SPA fallbacks) are treated as fetch failures so a stale cache can be retained. The cache is refreshed automatically on catalog access and is used by onboarding, catalog discovery, and dynamic model resolution. You can force a refresh and inspect the cache explicitly:

   # Force-refresh and print added / removed / changed model ids
   openclaw axonhub models sync
   
   # Report cache freshness, source URL, and model count
   openclaw axonhub models status
   
   # Machine-readable output; scope to an agent / auth profile
   openclaw axonhub models sync --json --agent <path> --profile <id>
   

   Output is deterministic and never prints your API key.

   After a successful onboarding/auth setup, stored models.providers.axonhub.models entries include per-model api and baseUrl for protocol routing (OpenAI / Anthropic / Gemini). Re-run auth setup if an older install still has a flat openai-completions-only catalog.

3. Generated enrichment-metadata sync (release-time). The plugin ships a small, deterministic metadata artifact (model-metadata.generated.ts) that maps model families to the correct AxonHub protocol endpoint (Gemini / Anthropic / OpenAI Responses / OpenAI Chat Completions) and to reasoning-effort hints. It is generated from a curated, reviewed source snapshot — never fetched at runtime — so releases stay reproducible. Maintainers regenerate it with:

   npm run sync:model-metadata     # regenerate from the curated source
   npm run check:model-metadata    # fail if regeneration would change output
   

   A scheduled GitHub workflow refreshes advisory reasoning hints from the pinned upstream catalog and opens a reviewable pull request only when the generated artifact actually changes.

Releasing

Publishing is tag-driven. Pushing a v* git tag triggers the Publish Package GitHub workflow, which typechecks, validates the manifest, runs tests, builds, then publishes to npm and ClawHub. The npm step is skipped automatically if the package.json version already exists on the registry.

To cut a release:

1. Bump the version in all three files so they stay in lockstep: package.json, openclaw.plugin.json, and package-lock.json (run npm install to update the lockfile after editing package.json). Follow semver: new models / routing / features → minor; fixes → patch.

2. Verify locally before tagging:

   npm run check:model-metadata   # generated artifact is up to date
   npm run typecheck
   npm test                       # full suite must pass
   npm run build
   

3. Commit with a chore: release vX.Y.Z message, push master, then push a matching tag:

   git tag vX.Y.Z
   git push origin vX.Y.Z
   

Never reuse or move an existing tag. If a release fails, bump to a new version rather than re-pushing the same tag.
