# 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) | GeckoTerm
