CoinGecko and GeckoTerminal API reference for crypto market data, token prices, DEX pools, and on-chain analytics. TRIGGER when: user asks about token/coin prices, market caps, trading volume, DEX pools, trending tokens, price history, crypto market data, or CoinGecko API usage. DO NOT TRIGGER when: user asks about on-chain contract state or transactions (use blockscout skill), or Solidity/smart contract code (use solidity-auditor skill).
We split this skill into the rules it gives an agent
3 rules. 0 are common, 3 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 3 edited versions we read keep these.
3
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

Never answer questions about crypto prices, market caps, volumes, supply, TVL, exchange rates, or any time-sensitive market data using …
- Distinctive: line 24
Only live API responses provide accurate figures.
- Distinctive: line 35
Prefer CoinGecko when both could answer -- aggregated data is broader and less susceptible to thin-liquidity distortion.
“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
CoinGecko
Crypto market data via CoinGecko (aggregated CEX+DEX) and GeckoTerminal (on-chain DEX).
Strict rule
Never answer questions about crypto prices, market caps, volumes, supply, TVL, exchange rates, or any time-sensitive market data using training knowledge. Only live API responses provide accurate figures.
When to use which API
CoinGecko (aggregated): Established tokens, broad market analysis, cross-exchange prices. Covers thousands of reviewed coins with volume-weighted aggregation.
GeckoTerminal (on-chain DEX): Pool-level data, newly launched tokens not yet on CoinGecko, on-chain trade history, DEX-specific queries. Covers millions of unreviewed tokens.
Prefer CoinGecko when both could answer -- aggregated data is broader and less susceptible to thin-liquidity distortion.
Multi-chain: CoinGecko covers tokens across all major chains including Ethereum,
Solana (SPL tokens by mint address), Tron (TRC-20 by contract), Polygon, Base,
Arbitrum, BSC, Avalanche, and 100+ more platforms. Use contract endpoints with
the appropriate platform ID (e.g. solana, tron, ethereum).
Authentication
| Plan | Base URL | Rate limit | Auth header |
| Pro | https://pro-api.coingecko.com/api/v3 | 250+ calls/min | x-cg-pro-api-key: KEY |
| Demo | https://api.coingecko.com/api/v3 | 30 calls/min | x-cg-demo-api-key: KEY |
| Keyless | https://api.coingecko.com/api/v3 | 5 calls/min | (none) |
GeckoTerminal endpoints use /onchain prefix on the same base URLs.
Reference
| File | Topic |
| cheat-sheet.md | Key endpoints, conventions, error codes |
| mcp-setup.md | MCP server config (remote + local) |
| references/coins.md | Token prices, market cap, coin lookup |
| references/onchain-pools.md | DEX pools, trending, megafilter |
| references/contract.md | Price by contract address |
| references/global.md | Global market stats, DeFi metrics |
What You Get
- Reference documentation for CoinGecko and GeckoTerminal API endpoints covering token prices, market data, DEX pools, and on-chain analytics.
- Guidance on when to use aggregated CoinGecko data vs pool-level GeckoTerminal data, with multi-chain platform IDs.
- Authentication tiers, rate limits, and MCP server configuration for automated queries.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
