Inputs and Outputs

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

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, etc.).
• You need exchange-level data — trust scores, volumes, per-pair tickers.
• You're screening across categories (DeFi, AI, L1s, etc.) or surfacing trending coins.

Do NOT use when:

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

Requirements

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