Crypto market data API

The crypto market data API returns one row per coin from CoinGecko's public markets endpoint — current price in your quote currency, market cap and rank, 24-hour volume, change, high and low, circulating and total supply, the all-time high with its date, plus icon and update time. Take the market-cap ranking as is, or narrow to specific coins or a category.

You choose the quote currency with vs_currency, filter to a set of coin_ids or a CoinGecko category slug, or leave both empty to walk the ranking. One run returns up to 250 coins. It reads CoinGecko's own public endpoint over the TLS tier — no browser — and stamps every row with last_updated so you always know how fresh the snapshot is.

$0.0002 per delivered coin, up to 250 coins per run. Nothing delivered means nothing charged.

How the crypto market data API works

You optionally set vs_currency (usd, eur, btc…), a list of coin_ids or a category, an order, and a max_results up to 250. With no filter it returns the market-cap ranking; with filters it returns just those coins, priced in your currency.

Worth knowing:

Inputs

Every input is optional. vs_currency sets the quote currency (default usd). coin_ids restricts to specific CoinGecko ids; category restricts to a sector slug; leave both empty for the market-cap ranking. order sets the sort, and max_results caps delivery at 250 coins.

What one coin looks like

Each coin is one flat row. price, market_cap, volume_24h, high_24h/low_24h and ath are all in currency; market_cap_rank is the global rank; change_24h_pct is the 24-hour move; circulating_supply/total_supply and ath_date round out the fundamentals. last_updated stamps the snapshot time and image is the coin icon.

What the Crypto market data API costs

$0.0002 per delivered coin ($0.20 per 1,000). Nothing delivered means nothing charged, and the $2 monthly free credit covers roughly 10,000 coins here. Volume tiers take up to 30% off.

$0.0002 per delivered coin, $0.20 per 1,000 — the cheapest tier on the menu. A full 250-coin ranking is five cents; refreshing a 50-coin watchlist every minute for a day is roughly 72,000 rows, about

4. You pay per coin returned, so a tight coin_ids filter is proportionally cheaper than pulling the whole board.

The $2 monthly allowance (no card) covers about 10,000 delivered coins, and volume tiers take up to 30% off. GET /v1/scraper/collectors returns the price your key pays.

Crypto market data API vs CoinGecko's own API

Being straight about this: CoinGecko publishes its own API, and it is the first-party source this collector reads. CoinGecko offers a free demo tier with a modest monthly call budget and per-minute rate limit, plus paid plans with higher throughput and a dedicated key. If CoinGecko data is all you need and your volume fits the demo tier, calling them directly is a perfectly good option — we will not pretend otherwise.

Where this collector earns its place is integration and scale: it delivers CoinGecko rows under the same QuantumProxies key as your other collectors, on the same per-row billing, with rotating exits so a burst of polling is not capped by a single IP's rate limit. You trade a first-party key you would otherwise manage for one pipeline and one bill.

Versus calling CoinGecko yourself

CoinGecko's endpoint is clean JSON, so the DIY cost is not parsing — it is operating it at volume:

  • Rate limits are per IP. Poll a large board frequently from one address and you hit the per-minute cap and start getting throttled. Rotating residential exits spread the calls out so a high-frequency job keeps flowing.
  • One key, many sources. If you are already pulling search, social and e-commerce rows through QuantumProxies, adding crypto here avoids standing up and rotating a separate CoinGecko credential and its own quota accounting.
  • Typed, stamped rows. You get a flat schema with last_updated on every row rather than mapping the raw response yourself each time the shape shifts.

If your only need is CoinGecko at low volume, their demo tier may be enough; at scale, or alongside other collectors, this and our residential proxies are the operational win.

What people build with it

Watchlist and portfolio snapshots

Pass a fixed coin_ids list and poll on an interval to record price, market cap and 24h move over time — a clean time series without running a streaming feed.

Sector and category screens

Filter by a CoinGecko category like stablecoins or a meme-token sector to pull just that basket, then rank by cap or volume for a screener.

Dashboards and alerts

Diff price or change_24h_pct between runs to fire threshold alerts, using last_updated to guard against acting on a stale snapshot.

Limits, freshness and the legal bit

One run returns up to 250 coins. The data is a snapshot stamped with last_updated, not a live tick stream — freshness is set by how often you re-run. Values are denominated server-side in vs_currency, and fields CoinGecko does not populate for a coin come back null rather than guessed. Runs parallelise up to your plan's rate limit — 60 a minute on pay-as-you-go, up to 1,200 on the top tier — which is also how you poll faster than one IP against CoinGecko could.

Legally: this is public market data, and reading it is broadly lawful, but CoinGecko's terms govern use of their endpoint and market data is not investment advice. Background only — not financial or legal advice.

FAQ

Is the crypto market data API free?

$2 of usage a month with no card, which at $0.0002 per coin is about 10,000 delivered coins. CoinGecko also runs its own free demo tier with a monthly call budget; this collector is worth it mainly when you want the data alongside other collectors or at higher polling rates.

Do I need a CoinGecko API key?

No. Your QuantumProxies API key is the only credential — the collector reads CoinGecko's public endpoint for you, so there is no separate CoinGecko key or quota to manage on your side.

Is the data real-time?

It is a point-in-time snapshot, stamped on every row with last_updated. There is no websocket or per-tick stream; you keep data fresh by polling on an interval, and rotating exits let you poll faster than a single IP's rate limit would allow.

Can I get just specific coins?

Yes. Pass a coin_ids list for a fixed watchlist, or a category slug for a sector; leave both empty to walk the market-cap ranking. You pay per coin returned, so a narrow filter costs proportionally less.
