## Frequently asked 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 works on every endpoint on this page: 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 2026-09-18 16:45 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?

Streaming over server-sent events is in preview. /sse/transactions pushes swaps on a pool or token as they land. Access is described at docs.dexpaprika.com/streaming/showcase-streams, and a running price stream is on dexpaprika.com/streaming/ethereum.

### 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.
