Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.02496 |
| Opus 5.5 | $0.00050 | $0.00998 |
| Sonnet 5.5 | $0.00025 | $0.00499 |
| Haiku 4.5 | $0.00012 | $0.00250 |
Grade A, and why
coingecko scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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).

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 211 lines · 124 tokens per session scan A b6f1743c3e81
coingecko is a skill published in the GitHub repository coingecko/skills (33 stars, last pushed 2mo ago), licensed MIT. It adds 124 tokens to every session and 2,496 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
