What is the DexPaprika API?

DexPaprika is a free API with no key covering decentralised exchange activity across dozens of blockchain networks. Endpoints expose networks, DEXes, liquidity pools, tokens, prices and OHLCV series.

Centralised exchange APIs cannot see on-chain trading, and on-chain data is fragmented across networks that each have their own explorers and conventions. DexPaprika normalises that: one interface covering dozens of networks with the same pool and token shapes throughout. The networks endpoint is the right starting point, because it returns the exact `id` strings every other endpoint expects.

Interpret the aggregates with care. `volume_usd_24h` and `pools_count` cover everything on a network, and on-chain volume can be inflated by wash trading, self-routing and pools with negligible real liquidity — a large number does not mean a large market. Values also come back as full-precision floats rather than rounded strings, so format for display rather than dumping them raw, and label prices derived from thin pools accordingly.

Parameters

Parameter	Type	Required	Description
`/networks`	path	Required	Lists supported networks with their ids and headline aggregates.
`/networks/{network}/pools`	path	Optional	Liquidity pools on a network, paginated. `ethereum`
`/networks/{network}/tokens/{address}`	path	Optional	Token detail by contract address.
`/pools/{network}/{address}/ohlcv`	path	Optional	OHLCV candles for a specific pool.
`limit / page`	query	Optional	Pagination on the collection endpoints. `50`

Response fields

[].idstring: Network identifier such as `ethereum` or `base` — the exact string other endpoints expect.
[].display_namestring: Human-readable network name for display.
[].volume_usd_24hnumber: 24-hour DEX volume across the network in US dollars, as a full-precision float.
[].txns_24hinteger: Swap transaction count over 24 hours.
[].pools_countinteger: Number of tracked liquidity pools on the network.

Common errors and how to fix them

404 on a network path

The network id is wrong.

Fix: Take the `id` value from `/networks` rather than guessing. Display names and ids differ — `Ton` versus `ton`.

Empty pools list

The network has no tracked pools, or the page is past the end.

Fix: Check `pools_count` from the networks endpoint before paging.

Unwieldy numbers in the UI

Values are full-precision floats.

Fix: Round for display. A volume figure carrying twelve decimal places is noise, not precision.

DexPaprika API — frequently asked questions

Is DexPaprika free to use?

Yes, the public endpoints need no key or registration. Caching is worth doing anyway, since network and pool listings change slowly.

How many blockchains does it cover?

Dozens, and the list changes. Call `/networks` for the current set with the exact ids every other endpoint expects, rather than hard-coding a list.

Is DEX volume comparable to centralised exchange volume?

Not directly. On-chain volume can include wash trading, self-routing and activity in pools with negligible real liquidity, so a headline figure overstates genuine market depth.

Can I get historical price data?

Yes. The OHLCV endpoint returns candles for a specific pool, addressed by network and pool address. Prices from thin pools are volatile and should be labelled as such.
