cryptologo

Python client for crypto-logo.com — the cryptocurrency logo database with 413 coins in SVG, PNG, WebP, JPEG, and ICO formats. Zero dependencies (stdlib urllib only).

Every logo is available as a scalable SVG vector and pre-generated raster derivatives in 13 standard sizes (16px to 2000px). Logos are served from Cloudflare R2 CDN with immutable cache headers for production-grade performance. The dataset is extracted from crypto-logo.com, which tracks logo assets for Bitcoin, Ethereum, Solana, and 410+ other cryptocurrencies ranked by market cap.

Install

pip install cryptologo

Quick Start

from cryptologo import CryptoLogo

client = CryptoLogo()

# List all 413 coins sorted by market cap
coins = client.list_coins()
for coin in coins[:5]:
    print(f"{coin.name} ({coin.ticker}) — rank #{coin.market_cap_rank}")
# Bitcoin (BTC) — rank #1
# Ethereum (ETH) — rank #2
# Tether (USDT) — rank #3

# Download Bitcoin logo as SVG
client.download_logo("bitcoin-btc", "svg")
# Saved: bitcoin-btc.svg

# Download Ethereum logo as 512x512 PNG
client.download_logo("ethereum-eth", "png", width=512)
# Saved: ethereum-eth-512x512.png

What You Can Do

List All Coins

The list_coins() method returns all 413 active coins with metadata including name, ticker, slug, format availability (PNG/SVG), localized search terms in 14 languages, and CoinGecko market cap ranking.

Field	Type	Description
name	str	Display name (e.g., "Bitcoin")
ticker	str	Trading symbol (e.g., "BTC")
slug	str	URL identifier (e.g., "bitcoin-btc")
has_png	bool	PNG logo available
has_svg	bool	SVG vector available
search_terms	list	Names in Korean, Japanese, Chinese, etc.
market_cap_rank	int/None	CoinGecko ranking

from cryptologo import CryptoLogo

client = CryptoLogo()
coins = client.list_coins()

# Filter coins that have SVG logos
svg_coins = [c for c in coins if c.has_svg]
print(f"{len(svg_coins)} coins have SVG logos")  # 413 coins have SVG logos

# Find a specific coin by ticker
btc = next((c for c in coins if c.ticker == "BTC"), None)
if btc:
    print(f"{btc.name}: slug={btc.slug}, rank=#{btc.market_cap_rank}")

Download Logos

Fetch logo image data as bytes or save directly to a file. SVG logos require no size parameter. Raster formats (PNG, WebP, JPEG, ICO) require a width.

from cryptologo import CryptoLogo

client = CryptoLogo()

# Get raw SVG bytes — scalable vector, ideal for web
svg_bytes = client.get_logo("bitcoin-btc", "svg")

# Get PNG at specific size — pre-generated, not resized on-the-fly
png_bytes = client.get_logo("solana-sol", "png", width=256)

# Download to file with auto-generated filename
path = client.download_logo("bitcoin-btc", "svg")
print(path)  # bitcoin-btc.svg

# Download to specific path
path = client.download_logo("ethereum-eth", "png", "logos/eth.png", width=128)

# ICO format for favicons (sizes: 16, 32, 48, 64, 128, 256)
client.download_logo("bitcoin-btc", "ico", width=32)

# OG image with white background (1200x630 for social sharing)
client.download_logo("bitcoin-btc", "png", width=1200, height=630, bg="FFFFFF")

Generate CDN URLs

Build URLs for direct embedding in HTML, Markdown, or documentation. The CDN serves pre-generated derivatives from Cloudflare R2 with Cache-Control: immutable — no Django server overhead.

from cryptologo import CryptoLogo

client = CryptoLogo()

# CDN URL for fast image display (recommended for <img> tags)
url = client.get_cdn_url("bitcoin-btc", "webp", 128)
# https://cdn.crypto-logo.com/logos/bitcoin-btc/128x128/transparent.webp

# CDN URL for SVG vector
url = client.get_cdn_url("ethereum-eth", "svg")
# https://cdn.crypto-logo.com/logos/ethereum-eth/vector.svg

# API URL (for downloads with Content-Disposition header)
url = client.get_logo_url("bitcoin-btc", "png", width=512, height=512)
# https://crypto-logo.com/api/logo/bitcoin-btc.png?w=512&h=512

Fetch Logo Variants and History

Some coins have alternate logo designs (full wordmark, diamond shape, animated) and historical versions showing brand evolution.

from cryptologo import CryptoLogo

client = CryptoLogo()

# Get a logo variant (alternate design)
full_logo = client.get_asset("versions/bitcoin-btc-full.svg")

# Get a historical logo version
old_logo = client.get_asset("history/bitcoin-btc-2009.png")

Cryptocurrency Logo Standards

SVG vs PNG — When to Use Which

Cryptocurrency projects publish official logos in SVG (vector) and PNG (raster). Choosing the right format depends on the use case.

Use Case	Recommended Format	Reason
Website/app UI	SVG	Scales to any resolution, small file size (~2-15KB)
Exchange listing	PNG 512x512	Standard requirement for CoinGecko, CoinMarketCap
Mobile app icon	PNG 128x128 or 256x256	iOS/Android require raster at specific sizes
Favicon	ICO 32x32 or SVG	ICO for legacy browsers, SVG for modern
Social media / OG image	PNG 1200x630	Open Graph standard with solid background
Print / merch	SVG	Infinite scalability without quality loss
Documentation	SVG or PNG 64-128px	SVG preferred, PNG for Markdown compatibility
Email signature	PNG 48-64px	Most email clients don't render SVG

Standard Sizes for Crypto Logos

The industry has converged on standard sizes. CryptoLogo pre-generates all 13 standard sizes for each coin.

Size	Common Use
16x16	Favicon, inline text icons
32x32	Favicon, small UI elements
48x48	Tab icons, small badges
64x64	List items, table cells
96x96	Grid thumbnails
128x128	Card previews, mobile
200x200	Profile images
256x256	Medium detail views
400x400	Large cards
512x512	Exchange listing standard
1024x1024	High-DPI displays
2000x2000	Maximum quality raster
1200x630	OG image (social sharing)

Brand Color Consistency

Each cryptocurrency has an official brand color (e.g., Bitcoin's #F7931A orange, Ethereum's #627EEA purple). CryptoLogo stores the brand_color for each coin, enabling consistent color theming in portfolio apps, dashboards, and data visualizations.

Notable brand colors:

• Bitcoin: #F7931A (orange) — designed by Satoshi-era contributor
• Ethereum: #627EEA (purple) — from the Ethereum Foundation brand kit
• Solana: #9945FF (violet) — gradient-based identity system
• Cardano: #0033AD (blue) — academic/formal positioning
• Dogecoin: #C2A633 (gold) — matches the Shiba Inu meme aesthetic
