Nous Tool Gateway
One subscription. Every tool built in.
The Tool Gateway is included with every paid Nous Portal subscription. It routes Hermes' tool calls — web search, image generation, text-to-speech, and cloud browser automation — through infrastructure Nous already runs, so you don't have to sign up with Firecrawl, FAL, OpenAI, Browser Use, or anyone else just to make your agent useful.
What's included
| Tool | What you get | |
|---|---|---|
| 🔍 | Web search & extract | Agent-grade web search and full-page extraction via Firecrawl. No rate limits to worry about — the gateway handles scaling. |
| 🎨 | Image generation | Nine models under one endpoint: FLUX 2 Klein 9B, FLUX 2 Pro, Z-Image Turbo, Nano Banana Pro (Gemini 3 Pro Image), GPT Image 1.5, GPT Image 2, Ideogram V3, Recraft V4 Pro, Qwen Image. Pick per-generation with a flag, or let Hermes default to FLUX 2 Klein. |
| 🔊 | Text-to-speech | OpenAI TTS voices wired into the text_to_speech tool. Drop voice notes into Telegram, generate audio for pipelines, narrate anything. |
| 🌐 | Cloud browser automation | Headless Chromium sessions via Browser Use. browser_navigate, browser_click, browser_type, browser_vision — all the agent-driving primitives, no Browserbase account required. |
All four are pay-as-you-use billed against your Nous subscription. Use any combination — run the gateway for web and images while keeping your own ElevenLabs key for TTS, or route everything through Nous.
Why it's here
Building an agent that can actually do things means stitching together 5+ API subscriptions — each with their own signup, rate limits, billing, and quirks. The gateway collapses that into one account:
- One bill. Pay Nous; we handle the rest.
- One signup. No Firecrawl, FAL, Browser Use, or OpenAI audio accounts to manage.
- One key. Your Nous Portal OAuth covers every tool.
- Same quality. Same backends the direct-key route uses — just fronted by us.
Bring your own keys anytime — per-tool, whenever you want to. The gateway isn't a lock-in, it's a shortcut.
Get started
There are three ways in — pick whichever fits where you are:
hermes setup --portal # Fresh install: Nous OAuth + set Nous as provider + turn on the Tool Gateway in one go
hermes model # Switch your inference provider to Nous Portal — Hermes then offers to turn on the gateway for all tools
hermes tools # Enable the gateway per-tool — pick "Nous Subscription" for any tool you want
hermes setup --portal and hermes model are the all-at-once paths: log in once, optionally flip every tool to the gateway. hermes tools is the à la carte path — turn on just the tools you want, one at a time.
You don't have to log in first. With hermes tools, the Nous-managed backends (Web search, Image, Video, TTS, Browser) are always listed, even if you've never signed into Nous Portal. Select one and Hermes runs the Portal login right there if you aren't already authenticated — no need to run hermes model beforehand. If your Nous OAuth is already active, selecting the backend enables it immediately with no extra prompt. This path only logs you in and turns on the one tool you picked — it does not switch your inference provider, and it does not prompt you to enable the gateway for every other tool.
Check what's active at any time:
hermes portal status # Portal auth + Tool Gateway routing summary
hermes portal tools # Gateway catalog with current routing per tool
hermes status # Full system status (Tool Gateway is one section)
hermes portal status shows a section like:
◆ Nous Tool Gateway
Nous Portal ✓ managed tools available
Web tools ✓ active via Nous subscription
Image gen ✓ active via Nous subscription
TTS ✓ active via Nous subscription
Browser ○ active via Browser Use key
Tools marked "active via Nous subscription" are going through the gateway. Anything else is using your own keys.
Eligibility
The Tool Gateway is a paid-subscription feature. Free-tier Nous accounts can use Portal for inference but don't include managed tools — upgrade your plan to unlock the gateway.
Mix and match
The gateway is per-tool. Turn it on for just what you want:
- All tools through Nous — easiest; one subscription, done.
- Gateway for web + images, bring your own TTS — keep your ElevenLabs voice, let Nous handle the rest.
- Gateway only for things you don't have keys for — "I already pay for Browserbase, but I don't want a Firecrawl account" works fine.
Switch any tool at any time via:
hermes tools # Interactive picker for each tool category
Select the tool, pick Nous Subscription as the provider (or any direct provider you prefer). No config editing required. If you aren't logged into Nous Portal yet, picking Nous Subscription kicks off the Portal login inline — you don't need to authenticate through hermes model first.
Using individual image models
Image generation defaults to FLUX 2 Klein 9B for speed. Override per-call by passing the model ID to the image_generate tool:
| Model | ID | Best for |
|---|---|---|
| FLUX 2 Klein 9B | fal-ai/flux-2/klein/9b | Fast, good default |
| FLUX 2 Pro | fal-ai/flux-2/pro | Higher fidelity FLUX |
| Z-Image Turbo | fal-ai/z-image/turbo | Stylized, fast |
| Nano Banana Pro | fal-ai/gemini-3-pro-image | Google Gemini 3 Pro Image |
| GPT Image 1.5 | fal-ai/gpt-image-1/5 | OpenAI image gen, text+image |
| GPT Image 2 | fal-ai/gpt-image-2 | OpenAI latest |
| Ideogram V3 | fal-ai/ideogram/v3 | Strong prompt adherence + typography |
| Recraft V4 Pro | fal-ai/recraft/v4/pro | Vector-style, graphic design |
| Qwen Image | fal-ai/qwen-image | Alibaba multimodal |
The set evolves — hermes tools → Image Generation shows the current live list.
Configuration reference
Most users never need to touch this — hermes model and hermes tools cover every workflow interactively. This section is for writing config.yaml directly or scripting setups.
Per-tool use_gateway flag
Each tool's config block takes a use_gateway boolean:
web:
backend: firecrawl
use_gateway: true
image_gen:
use_gateway: true
tts:
provider: openai
use_gateway: true
browser:
cloud_provider: browser-use
use_gateway: true
Precedence: use_gateway: true routes through Nous regardless of any direct keys in .env. use_gateway: false (or absent) uses direct keys if available and only falls back to the gateway when none exist.
Disabling the gateway
web:
use_gateway: false # Hermes now uses FIRECRAWL_API_KEY from .env
hermes tools automatically clears the flag when you pick a non-gateway provider, so this usually happens for you.
Self-hosted gateway (advanced)
Running your own Nous-compatible gateway? Override endpoints in ~/.hermes/.env:
TOOL_GATEWAY_DOMAIN=your-domain.example.com
TOOL_GATEWAY_SCHEME=https
TOOL_GATEWAY_USER_TOKEN=your-token # normally auto-populated from Portal login
FIRECRAWL_GATEWAY_URL=https://... # override one endpoint specifically
These knobs exist for custom infrastructure setups (enterprise deployments, dev environments). Regular subscribers never set them.
FAQ
Does it work with Telegram / Discord / the other messaging gateways?
Yes. Tool Gateway operates at the tool-execution layer, not the CLI. Every interface that can call a tool — CLI, Telegram, Discord, Slack, IRC, Teams, the API server, anything — benefits from it transparently.
What happens if my subscription expires?
Tools routed through the gateway stop working until you renew or swap in direct API keys via hermes tools. Hermes shows a clear error pointing at the portal.
Can I see usage or costs per tool?
Yes — the Nous Portal dashboard breaks usage down by tool so you can see what's driving your bill.
Is Modal (serverless terminal) included?
Modal is available as an optional add-on through the Nous subscription, not part of the default Tool Gateway bundle. Configure it via hermes setup terminal or directly in config.yaml when you want a remote sandbox for shell execution.
Do I need to delete my existing API keys when I enable the gateway?
No — keep them in .env. When use_gateway: true, Hermes skips direct keys and uses the gateway. Flip the flag back to false and your keys become the source again. The gateway isn't a lock-in.
