CoinGecko markets without the rate-limit wall

CoinGecko's free API is the most-cited crypto market data source for a reason — no key on the public endpoints, deep coverage, clean JSON. The catch is the rate limit: hammer it from a shared datacenter IP and you are looking at 429s faster than you can paginate. For a one-off pull it is fine; for a standing dashboard feed it gets annoying.

CoinGecko Markets — Crypto Data API runs that pull for you on Apify's infrastructure, with politeness built in. Top markets by cap, specific tickers, or what is moving right now:

// top coins by market cap
{ "mode": "markets", "vsCurrency": "usd", "perPage": 50, "page": 1 }

// specific tickers
{ "mode": "coins", "vsCurrency": "usd", "coinIds": ["bitcoin", "ethereum", "solana"] }

// what is trending
{ "mode": "trending" }

Each record: id, symbol, name, image, current_price, market_cap, market_cap_rank, total_volume, price_change_percentage_24h, ath, atl, and the rest. All string-typed so the dataset column model stays happy.

The point isn't the data, it's the cadence

CoinGecko's numbers are a free API call away — the value here is the schedule. A standing run every few minutes gives you a time-series you own: price and volume snapshots you can diff, chart, or feed to an agent without standing up a worker, a cron, and a rate-limit backoff of your own. Trending mode is the morning watchlist.

Clean by construction

Every value is stringified and nulls collapse to empty strings, so a run that hits a partial response still produces a valid typed dataset. Pair it with the Dataset Drift & QA actor to watch your own crypto feed for gaps.
