realcryptocap

Live crypto prices, real market cap rankings and AI market briefs from RealCryptoCap, free with no API key. Real market cap ranks native crypto only: stablecoins, wrapped/staked receipts and tokenized assets are left out. Three tools (rcc_price, rcc_top, rcc_market_brief), a /crypto slash command for an instant price table with no model call, and a bundled skill that tells the agent to use live data instead of quoting prices from memory. Disclosure — HTTPS GET requests to realcryptocap.com only (/api/cg, /api/market-analysis, /api/news); an optional REALCRYPTOCAP_API_KEY, read through Hermes's secret scope, is sent as a Bearer header to realcryptocap.com only; rcc_market_brief sends the fetched market data (prices, analysis, headlines, no conversation content) to the user's active model through ctx.llm. No shell, no file writes, no background processes, no telemetry, no stored credentials. Standard library only. Market data, not financial advice.

About

RealCryptoCap for Hermes Agent

Live crypto prices, real market cap rankings and AI market briefs inside Hermes. Free, no API key, no account.

Ask Hermes "what's BTC at?", "top 20 coins" or "give me a crypto morning brief" and it answers from live RealCryptoCap data instead of guessing from memory or running a slow web search.

Real market cap ranks native crypto only. Stablecoins (USDT, USDC), wrapped and staked receipts (WBTC, stETH) and tokenized assets are left out, so the Top 10 is ten actual cryptocurrencies.

What you get

| | |
|---|---|
| rcc_price | Price, rank, real market cap, 24h change, 24h high/low and volume. Takes tickers (BTC), names (Solana) or CoinGecko ids. |
| rcc_top | Top coins by real market cap (up to 50 free, 500 with a key). |
| rcc_market_brief | A short trader brief: bias, key levels, movers and headlines, written by your own Hermes model from live data via ctx.llm. If no model is available it returns the data for the agent to summarise. |
| /crypto | Instant price table with no model call: /crypto btc eth sol, /crypto top 20. |
| Skill | realcryptocap:realcryptocap tells the agent which tool to use and to never quote prices from memory. |

Results are cached for 60 seconds. Errors come back as JSON, never as crashes.

Install

hermes plugins install jamesparser/realcryptocap-hermes
hermes plugins enable realcryptocap

Or copy this folder to ~/.hermes/plugins/realcryptocap/ and run hermes plugins enable realcryptocap.

Optional: RealCryptoCap API key

Everything above works free. A Pro or Ultra key from realcryptocap.com/api raises rcc_top to the Top 500. Set it in Settings → Plugins → realcryptocap in Hermes Desktop, or add REALCRYPTOCAP_API_KEY=... to your Hermes .env. Pro/Ultra also includes the full RealCryptoCap API, CLI and MCP server (signals, Fear & Greed, derivatives, ETF flows).
