Crypto Market Data 🪙

Query cryptocurrency prices, charts, exchange data, categories, trending searches, and news through AIsa's CoinGecko-backed API.

Use this skill when you need current or historical crypto market data, token lookup by contract address, market-cap screening, exchange research, or category-level analysis.

Compatibility

Works with any agentskills.io-compatible harness, including:

Claude Code and Claude
OpenAI Codex
Cursor
Gemini CLI
OpenCode, Goose, OpenClaw, Hermes
and other tools that implement the Agent Skills specification

Requires Python 3, a POSIX shell, and AISA_API_KEY from aisa.one.

News and trending

Inputs and outputs

Input: coin IDs such as bitcoin, ethereum, and solana; fiat or crypto vs_currency codes such as usd, eur, and btc; category IDs; exchange IDs; or 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. Depending on the command, outputs include price dictionaries, coin or exchange objects, arrays of timestamped [ts, value] pairs for charts, [ts, o, h, l, c] tuples for OHLC, ticker arrays, and news or trending 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 such as ethereum, binance-smart-chain, or polygon-pos.
You need exchange-level data such as trust scores, volumes, and per-pair tickers.
You want to screen categories like 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 order-book depth on prediction markets 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
