CoinMarketCap from the command line
Crypto prices, market metrics, news and on-chain data.
gbrain.io
Crypto prices, market metrics, news and on-chain data. GBrain gives CoinMarketCap, and every other application you connect, a command line.
One price for one person: CoinMarketCap and every other application GBrain connects, from a terminal or any AI. Cancel any time.
CoinMarketCap 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 CoinMarketCap command, once CoinMarketCap is connected gbrainio tool help coinmarketcap
CoinMarketCap tracks prices and market data for cryptocurrencies. Connected to a workspace, GBrain can answer “how has ETH dominance moved this month, and what is driving it?” or pull the latest news on a token before a meeting.
The connection only reads.
Each terminal reaches CoinMarketCap at the level set for it in the browser: Off, or Read, which only reads, as CoinMarketCap describes its tools. A terminal reads its level and never raises it.
Each of CoinMarketCap'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 CoinMarketCap 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 coinmarketcap reads it back.
CoinMarketCap's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once CoinMarketCap is connected, gbrainio tool help coinmarketcap 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 CoinMarketCap at its own server, mcp.coinmarketcap.com. On CoinMarketCap'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 CoinMarketCap 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.
