What the Curve Finance API returns

Pools

The pools the API indexes for Curve Finance, across every version on this page. A record carries both sides of the pair, current reserves, price in USD, and rolling volume and transaction counts.

Swaps

Individual transactions, newest first, with token symbols, USD prices at the time and the block they landed in. Reading them through the API needs a Dev plan or above.

Candles and streams

Historical OHLCV on any pool at the interval you ask for. Server-sent event streaming pushes swaps on a Dev plan or above, and prices run live on the Ethereum streaming page.

The data is the same shape on all 36 chains DexPaprika indexes. A query written against Curve Finance runs against any other venue once you change the network and the dex_name.

Questions

Do I need an API key to query Curve Finance data?

A free API key is the place to start. It needs no credit card and covers pools, tokens, DEXes and candles; swaps need a Dev plan or above. Register one at console.dexpaprika.com. Current quotas are on the pricing page.

Which Curve Finance version is a swap from?

Read factory_id on the transaction row: 0x98ee…af7f is Curve Twocrypto. Pool records carry dex_id directly: curve is Curve and curve_twocrypto is Curve Twocrypto.

How do I list only Curve Finance pools on Ethereum?

Call /networks/ethereum/pools/search with dex_name=curve, then with dex_name=curve_twocrypto for the other versions. Add order_by=volume_usd_24h to get the busiest first.

How fresh is the Curve Finance data?

On the free plan, data can run a short way behind the chain. Paid plans serve it in real time. The figures on this page were read from the API at 2026-11-02 22:05 UTC.

What counts as one request?

One call is one credit, including a call that returns many rows. Batch endpoints bill per item. Each streaming update also counts as one.

Can I stream Curve Finance swaps instead of polling?

Yes. /sse/transactions pushes swaps on a pool or token as they land, and it needs a Dev plan or above. The transactions streaming docs cover it, and a running price stream is on the Ethereum streaming page.

How do I send my key once I have one?

Put the key in the Authorization header on its own, with nothing in front of it.

Which host do I call?

api.dexpaprika.com with a free key. Pro and Enterprise keys go to api-pro.dexpaprika.com.
