Crypto market data API

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

What a crypto market data API does

Most "crypto price" feeds hand you a single number per symbol and leave the rest — cap, volume, supply, ATH — to stitch from other calls. This reads the markets table, so every row already carries the columns an analysis joins on, in the vs_currency you asked for rather than a USD figure you then convert.

The source is CoinGecko's aggregate across exchanges, not one venue's order book, so the price is a market view rather than a single exchange's. You pass coin ids, a category slug like stablecoins, or nothing at all for the ranking; up to 250 coins come back in one run, each stamped with the time CoinGecko last updated it.

What one coin looks like

Every delivered coin carries these fields. Nullable means the source did not publish it — the field stays empty instead of being guessed.

Field	Type	What it holds
`rank`	integer	Row order as returned.
`id`	string	CoinGecko coin id.
`symbol`	string	Ticker symbol (uppercase).
`name`	string · nullable	Coin name.
`price`	number · nullable	Current price in vs_currency.
`currency`	string	Quote currency (uppercase).
`market_cap`	number · nullable	Market capitalization.
`market_cap_rank`	integer · nullable	Global market-cap rank.
`volume_24h`	number · nullable	24h trading volume.
`change_24h_pct`	number · nullable	24h price change %.
`high_24h`	number · nullable	24h high.
`low_24h`	number · nullable	24h low.
`circulating_supply`	number · nullable	Circulating supply.
`total_supply`	number · nullable	Total supply.
`ath`	number · nullable	All-time high price.
`ath_date`	string · nullable	All-time high date.
`image`	string · nullable	Coin icon URL.
`last_updated`	string · nullable	Data timestamp.

Inputs

The whole request. Anything you leave out falls back to the default shown in the catalog.

Input	Type	Required	What it does
`vs_currency`	string	no	Quote currency (usd, eur, btc…).
`coin_ids`	array	no	Specific CoinGecko ids (bitcoin, ethereum…). Empty = ranking order.
`category`	string	no	CoinGecko category slug, e.g. stablecoins, meme-token.
`order`	string	no	Sort order (default market_cap_desc). One of: `market_cap_desc`, `market_cap_asc`, `volume_desc`, `volume_asc`, `id_asc`, `id_desc`.
`max_results`	integer	no	How many coins to deliver at most (1–250). You pay only for delivered coins.

What people build with the crypto market data API

Three shapes of work this endpoint was designed around.

Portfolio valuation

Price a holdings list in one call by passing its coin ids, each row already denominated in your reporting currency via vs_currency.

Market dashboards

Rank the top coins by market cap or volume and read change, high and low for a movers board without a second request.

Category screening

Pull a category such as stablecoins or meme-token and compare cap, volume and supply across only that segment.

Crypto market data API versus rolling your own

The differences that actually cost time when you build this in-house.

	DIY scraper	This collector
Per row	One price number per call	Price, cap, volume, supply, 24h range and ATH together
Quote currency	USD you convert yourself	Any vs_currency, priced at read time
Selection	One coin per request	Ranking, an id list, or a category in one run

FAQ

Questions we get about the crypto market data API.

Something else? Ask us →

Is this real-time or a snapshot?

Each row carries CoinGecko's last_updated timestamp, so you read the latest aggregate it publishes and can see how fresh each coin is. It is a poll of the markets endpoint per run, not a streaming socket.

Can I price in EUR or BTC instead of USD?

Yes. vs_currency takes usd, eur, btc and the other quotes CoinGecko supports, and every numeric field — price, market cap, volume, ATH — comes back already denominated in it.

How do I read just the coins I hold?

Pass their CoinGecko ids in coin_ids (bitcoin, ethereum, solana…). Leave it empty for the market-cap ranking instead, or add a category to scope that ranking to one segment.

Is there a free crypto market data API?

Every account gets $2 of credit every month with no card, which is about 10,000 delivered coins on this endpoint at $0.0002 each. It renews monthly, and a run that delivers nothing is never billed — so a failed or blocked attempt does not eat the allowance.

How much does one run cost?

Multiply the rows you actually receive by $0.0002. A run capped at 250 coins — the maximum for this collector — costs $0.05 if every row comes back, and less when the source has fewer. Volume tiers take up to 30% off, and GET /v1/scraper/collectors returns the price your key actually pays.
