CoinGecko Tokens by Category Scraper

Pulls every token listed in a CoinGecko category (DeFi, meme, AI, L1, ecosystem tags, etc.) with current price, market cap, 24h volume, rank, and price change. Uses the free public CoinGecko API — no API key required.

How to use

Pass a JSON input with a category array of CoinGecko category slugs.
Category slugs come from the category_id field of the /coins/categories/list endpoint — they are not human-readable names.

{
  "category": [
    "layer-1",
    "meme-token",
    "decentralized-finance-defi",
    "artificial-intelligence",
    "gaming",
    "ethereum-ecosystem",
    "solana-ecosystem"
  ]
}

Field	Type	Default	Description
category	string[]	["layer-1","meme-token","artificial-intelligence"]	One or more CoinGecko category slugs. Invalid slugs are skipped gracefully.

Each category returns up to 100 tokens ordered by market cap descending.
Large categories (e.g. ethereum-ecosystem has 4000+ tokens) are intentionally truncated to the top 100 — buyers want the leaders, not the long tail.

Known slug quirks

• polygon-ecosystem- has a trailing dash (CoinGecko's bug, not ours).
• CoinGecko deprecated some legacy slugs in 2025 — if a slug returns 0 results, verify it against /coins/categories/list.

Pricing

Event	Cost
dataset-item — per token row returned	$0.001

A run over 3 categories averaging 80 tokens each costs $0.24.

Buyer

• Portfolio trackers monitoring which tokens dominate a sector (AI coins, RWA, L2s) without a CoinGecko Pro subscription.
• Quant researchers seeding a watchlist from an entire category in one API call.
• Trading bots that need a refreshed universe of tokens per sector on a schedule.
• DeFi dashboards displaying sector-level market cap and volume aggregates.
• Crypto journalists snapshotting category leaders at publication time.
