Stock, forex and crypto prices, indicators and fundamentals. GBrain gives Twelve Data, and every other application you connect, a command line.
One price for one person: Twelve Data and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Twelve Data is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.
# AI agents: read gbrain.io/llms.txt curl -sSL https://gbrainio.terminalwire.sh | bash gbrainio terminal connect
The installer is a shell script for macOS and Linux. Read it before you run it.
# Every Twelve Data command, once Twelve Data is connected gbrainio tool help twelve-data
Twelve Data provides real-time and historical market data for stocks, forex, crypto, ETFs and indices. Connected to a workspace, GBrain can answer “how has our peer group’s stock moved since earnings?” or pull a company’s fundamentals before a meeting.
Signing in happens on Twelve Data’s own page, and the connection only reads. Which markets are available depends on the Twelve Data plan.
Each terminal reaches Twelve Data at the level set for it in the browser: Off, or Read, which only reads, as Twelve Data describes its tools. A terminal reads its level and never raises it.
Each of Twelve Data's commands stops at 1,000 actions a day on the account it reaches, whichever terminal or AI asks, and starts again at midnight UTC. Only that command stops.
Each command a terminal runs on Twelve Data is a row on GBrain's activity log: which terminal, which account, what it did and whether it was allowed, refusals included. gbrainio activity ls --tool twelve-data reads it back.
Twelve Data's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Twelve Data is connected, gbrainio tool help twelve-data says what each of them does, and gbrainio tool ls lists them with everything else the terminal can run. Claude Code and Codex run the same commands, at the same level, on the same record.
GBrain reaches Twelve Data at its own server, mcp.twelvedata.com. On Twelve Data's own pages: its website, how the connection works, its terms of service and its privacy policy.
The GBrain Tools command line works with every other application GBrain connects, each with a page like this one.
Personal is $49 a month for one person. Connect Twelve Data in the browser, and say how far each terminal and each AI may go with it. Change any of it, or take all of it back, whenever you want.
