## What it does

This skill connects agents to CoinGecko and GeckoTerminal endpoints for crypto market data. It enforces a strict rule: the assistant must never answer price questions from training memory. Every figure requires a live API call. The skill inspects the user tier before writing code or running requests. Free tiers cannot pull historical data beyond 365 days, so catching this early prevents error `10012`.

The workflow accounts for environment boundaries. In Claude, it directs users to allow `api.coingecko.com` and `pro-api.coingecko.com` in capability settings. Because `fetch` calls fail inside artifacts, the skill defaults to `curl` through the terminal. Keyless calls are capped at 5 requests per minute. Checking credentials upfront keeps the agent from hitting rate walls during multi-step analysis.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add coingecko/skills --skill coingecko -a claude-code
```
```bash
npx skills add coingecko/skills --skill coingecko-coingecko -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/coingecko-coingecko/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/coingecko-coingecko/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add coingecko/skills --skill coingecko-coingecko -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/coingecko-coingecko/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add coingecko/skills --skill coingecko-coingecko -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/coingecko-coingecko/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install coingecko/skills coingecko-coingecko
```

2. **Manually: put the files in place**

```bash
npx skills add coingecko/skills --skill coingecko-coingecko -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/coingecko/skills
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/coingecko-coingecko/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add coingecko/skills --skill coingecko-coingecko -a opencode
```

### Claude.ai

**Claude.ai**

  Use this skill for any request involving cryptocurrency market data, coin prices,
  trading volume, market cap, OHLC charts, historical data, exchanges, derivatives,
  NFTs, DeFi, on-chain token data, liquidity pools, DEX data, or anything powered
  by CoinGecko or GeckoTerminal APIs. Trigger this skill whenever the user asks
  about crypto prices, token data, market trends, or wants to call any CoinGecko
  or GeckoTerminal endpoint — even if they don't explicitly say "CoinGecko". Also
  trigger when the user asks about API keys, rate limits, or authentication for
  these APIs.

# CoinGecko Skill

## When to use

Trigger this skill when the user's request matches **any** of the following:

### Crypto market data queries
- Coin/token prices, market caps, trading volume, price changes
- Historical price data, OHLC charts, time-range queries
- Circulating or total supply data
- Global crypto market stats (total market cap, BTC dominance, DeFi TVL)
- Trending coins, top gainers/losers, newly listed coins

### Token and contract lookups
- Looking up a token by its contract address (e.g. `0x...`)
- Token metadata, categories, or platform info
- Comparing multiple coins or tokens

### Exchange and trading data
- Exchange listings, volume, tickers, trust scores
- DEX-specific data (Uniswap, PancakeSwap, etc.)
- Derivatives exchanges and tickers (futures, perpetuals)

### On-chain / DeFi data (GeckoTerminal)
- Liquidity pool data, trending/new pools, pool search
- On-chain token prices, holder data, top traders
- OHLCV candles or trade history for specific pools or tokens
- DEX and network discovery (supported chains, DEXes)
- On-chain pool categories and filtering

### NFT data
- NFT collection prices, floor prices, market data
- NFT collection charts and tickers

### Other triggers
- Building dashboards, visualizations, or apps with crypto data
- Questions about CoinGecko or GeckoTerminal API capabilities, endpoints, or rate limits
- API key setup, authentication, plan tiers, or pricing questions
- "What crypto data is available?" or similar exploratory questions
- User mentions CoinGecko, GeckoTerminal, or shares a CoinGecko URL
- Investment calculators, portfolio trackers, or ROI calculations involving crypto
- Public company/institution crypto treasury holdings (e.g. "how much BTC does MicroStrategy hold?")

---

You have access to the CoinGecko API (aggregated data) and the GeckoTerminal API
(on-chain DEX data). Together they cover virtually all crypto market data needs.
Both APIs share the same API key and plan tier. GeckoTerminal endpoints use the
same base URL as CoinGecko plus an `/onchain` path prefix (details in `references/core.md`).

## STRICT RULE — All market data must come from live API calls

**Never answer questions about crypto prices, market caps, volumes, supply, TVL, exchange
rates, or any time-sensitive market data using training knowledge.** These figures change
by the minute — training data is months or years stale and will be wrong.
