crypto-data-aggregation-guide

A guide to CryptoDataPy, a Python library that combines data from more than 20 cryptocurrency sources behind one interface.

In plain words
What is it for?
It is for collecting prices, blockchain activity, social data, derivatives, and economic indicators from sources such as CoinGecko, DeFi Llama, and Binance.
Why use it?
It removes the need to learn and maintain a separate connection for each source and data format.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

crypto-data-aggregation-guide scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CryptoDataPy — Crypto Data Aggregation Guide

CryptoDataPy is a Python library that unifies 20+ crypto data sources into a single interface. One import, one API call — get prices, on-chain metrics, social data, derivatives, and macro indicators.

Supported Sources

Source Data Type API Key Required
CoinGecko Prices, market cap, volume Free tier available
DeFi Llama TVL, yields, stablecoin data No
Glassnode On-chain metrics Yes
CryptoCompare OHLCV, social stats Free tier available
Messari Asset profiles, metrics Free tier available
Dune Analytics Custom SQL queries Yes
Etherscan Gas, transactions Free tier available
Alternative.me Fear & Greed Index No
DexScreener DEX prices, pools No
Binance OHLCV, order book No
And 10+ more Various Various

Quick Start

pip install cryptodatapy
from cryptodatapy import DataRequest

# Get Bitcoin daily prices from multiple sources
dr = DataRequest(
    tickers=['BTC', 'ETH', 'SPA'],
    fields=['close', 'volume', 'market_cap'],
    freq='daily',
    start_date='2024-01-01'
)

data = dr.fetch()
print(data.head())

Data Types

Price Data

# OHLCV data
dr = DataRequest(
    tickers=['SPA', 'ETH'],
    fields=['open', 'high', 'low', 'close', 'volume'],
    freq='1h',
    source='binance'
)

On-Chain Metrics

# Active addresses, transaction count, hash rate
dr = DataRequest(
    tickers=['ETH'],
    fields=['active_addresses', 'tx_count', 'hash_rate'],
    freq='daily',
    source='glassnode'
)

DeFi Metrics

# TVL, yields, protocol revenue
dr = DataRequest(
    tickers=['sperax', 'aave', 'uniswap'],
    fields=['tvl', 'revenue', 'fees'],
    freq='daily',
    source='defillama'
)

Social Data

# Social volume, sentiment, developer activity
dr = DataRequest(
    tickers=['SPA', 'BTC'],
    fields=['social_volume', 'dev_activity', 'github_stars'],
    freq='daily',
    source='santiment'
)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

crypto-data-aggregation-guide is a skill published in the GitHub repository nirholas/three.ws (107 stars, last pushed 3d ago), licensed Apache-2.0. It adds 65 tokens to every session and 1,171 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
