What did USDC settle at today? Check the web and give me one line.
USDC is holding its dollar peg at $1.00 across all three trackers — no depeg events in the last 24 hours.

Web search and page fetch are built in; wire any MCP server for more. Every model gets hands, not just words.
A terminal inside
An embedded terminal runs Claude Code without leaving the deck. Chat on one side, ship on the other.

Live token and dollar readouts per reply, 30-day spend per provider, automatic fallback when a route fails.

Questions, answered.
Where do my API keys live?
In your operating system's keychain — Windows Credential Manager on Windows. Never in plain files, and never sent anywhere except directly to the provider you're calling.
Does Nexus work offline?
With local models through Ollama, yes — chat runs entirely on your machine. Cloud providers need a connection, and your license key itself activates offline.
Which models can I use?
Anything your keys unlock: GPT, Claude, Gemini, Mistral, Groq, DeepSeek and 40+ more providers, plus any model you run locally with Ollama.
What happens when the trial ends?
Chat locks until you add a license key. Nothing is deleted — your conversations, keys and settings stay on your machine and unlock with the key.
How do payments work?
You top up credits ($20–$1000) by sending USDC or USDT to a payment address — no card, no processor. Your key then renews itself for 20 credits a month. Crypto transfers can't be reversed, so all sales are final; that's what the free trial is for.
What if I run out of credits?
Your key keeps working through a 3-day grace period while we email you. After that it pauses — nothing is deleted — and topping up reactivates it automatically within minutes.
Do I need an account?
Not for the app — the trial has no signup and there's no telemetry. Buying a key uses a simple email account so your credits and license have a home you can sign back into.
How do updates arrive?
Nexus checks for new releases and installs updates from inside the app — one click on the status bar when a new version lands.
