Inputs and outputs

• Input: coin IDs (for example bitcoin, ethereum, solana), fiat/crypto vs_currency codes (usd, eur, btc), category IDs, exchange IDs, or supported platform + contract address pairs. Use coins list and exchanges id-map to resolve user-friendly names to CoinGecko IDs.
• Output: JSON printed to stdout, matching the CoinGecko schema for each endpoint: price dictionaries, coin and exchange objects, arrays of timestamped [ts, value] pairs for charts, [ts, o, h, l, c] tuples for OHLC, ticker arrays, and related market-data payloads.

When to use / When not to use

Use when:

• You need current or historical crypto prices, market caps, volumes, or charts.
• You need to look up a token by its on-chain contract address (ethereum, binance-smart-chain, polygon-pos, and similar supported platforms).
• You need exchange-level data such as trust scores, volumes, or per-pair tickers.
• You want to screen categories such as DeFi, AI, or L1s, or surface trending coins.

Do not use when:

• You need equities or traditional finance data — use the marketpulse skill.
• You need prediction-market order-book depth for platforms such as Polymarket or Kalshi — use prediction-market-data.
• You need on-chain wallet balances, transfers, or gas traces — CoinGecko is a pricing and market-data source, not a node RPC.

Requirements

• Python 3, curl, POSIX shell
• AISA_API_KEY — required, get one at aisa.one
