Each series is one version on one chain, keyed by protocol, version and chain. Category fields are null where a deployment has no such trading, so pass selections. One row per spot DEX deployment, one protocol version on one blockchain, keyed by protocol, version and chain: name, protocol, version, exchange type, chain and network slug. The id is the series key of the spot-dex-protocols-by-chain timeseries model. | | | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------ | | Access | Projects\_protocols\_unified | | Tabular model | `spot-dex-protocol-chains`: primary key `id`, identifiers `slug` | | Timeseries model | `spot-dex-protocols-by-chain`: intervals `1d`, series key `id` (Protocol Version Chain ID), every series available in one call | ## Endpoints One page of rows with per-column filters, sorting and pagination. Every series in one request, or the named ones. One series over a time window, keyed by its Protocol Version Chain ID. ## Metrics 16 metrics. Use the `Field` value in `selections`; every point starts with the timestamp and continues in this order. | Field | Name | Type | Unit | Description | | -------------------------------------- | ------------------------------ | ------- | ---- | ------------------------------------------------------------- | | `volume-usd` | Volume (USD) | float64 | | Total spot trading volume in USD. | | `correlated-volume-usd` | Correlated Volume (USD) | float64 | | Volume between correlated assets (wash-adjusted view) in USD. | | `trade-count` | Trade Count | float64 | | Total trade count. | | `aggregator-volume-usd` | Aggregator Volume (USD) | float64 | | Volume routed through aggregators in USD. | | `platform-volume-usd` | Platform Volume (USD) | float64 | | Volume traded directly on the platform in USD. | | `aggregator-trade-count` | Aggregator Trade Count | float64 | | Trades routed through aggregators. | | `platform-trade-count` | Platform Trade Count | float64 | | Trades executed directly on the platform. | | `category-nativestablecoin-volume-usd` | Native Stablecoin Volume (USD) | float64 | | Volume in native stablecoin pairs in USD. | | `category-chaintoken-volume-usd` | Chain Token Volume (USD) | float64 | | Volume in chain token pairs in USD. | | `category-foreigntoken-volume-usd` | Foreign Token Volume (USD) | float64 | | Volume in foreign token pairs in USD. | | `category-stablecoinswaps-volume-usd` | Stablecoin Swaps Volume (USD) | float64 | | Volume in stablecoin-to-stablecoin swaps in USD. | | `category-lstswaps-volume-usd` | LST Swaps Volume (USD) | float64 | | Volume in liquid staking token swaps in USD. | | `category-composites-volume-usd` | Composites Volume (USD) | float64 | | Volume in composite token pairs in USD. | | `category-tokenizedassets-volume-usd` | Tokenized Assets Volume (USD) | float64 | | Volume in tokenized asset pairs in USD. | | `category-projecttokens-volume-usd` | Project Tokens Volume (USD) | float64 | | Volume in project token pairs in USD. | | `category-memes-volume-usd` | Memecoin Volume (USD) | float64 | | Volume in memecoin pairs in USD. | ## Columns Use the `Field` value in `selections`, `sortBy`, and as the base of a filter parameter (`Field` plus one of its `Filters` suffixes). | Field | Type | Filters | Sort | Description | | ----------------- | ------ | --------------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `id` | string | `Eq`, `IsOneOf` | | The series key of the spot-dex-protocols-by-chain timeseries model, the protocol, version and chain joined with underscores (uniswap\_v3\_arbitrum). (primary key) | | `name` | string | `Eq`, `IsOneOf`, `Contains` | default | The display name of the deployment, the protocol's short name followed by its version (uniswap v3). | | `slug` | string | `Eq`, `IsOneOf` | yes | The protocol's project slug; null for venues without a project record. (identifier 1) | | `exchangeID` | string | `Eq`, `IsOneOf` | yes | The protocol's short name, the id in spot-dex-protocols (uniswap). | | `exchangeVersion` | string | `Eq`, `IsOneOf` | | The version label of the deployment (v2, v3, settler). | | `exchangeType` | string | `Eq`, `IsOneOf` | | The exchange design (for example concentrated-liquidity, constant-product, rfq, orderbook or bonding-curve). | | `chain` | string | `Eq`, `IsOneOf` | | The short name of the chain the deployment runs on (ethereum, arbitrum, solana). | | `networkSlug` | string | `Eq`, `IsOneOf` | | The chain's slug in the blockchains model (arbitrum-one). | ## Example ```bash curl theme={null} curl "https://api.blockworks.com/query/timeseries/spot-dex-protocols-by-chain/1d/0x%20API_settler_arbitrum?timeframe=7d&selections=volume-usd,correlated-volume-usd" \ -H "X-Blockworks-API-Key: $BLOCKWORKS_API_KEY" ``` See [Get Spot DEX Protocol Chain timeseries](/api-reference/data-api/spot-dexes/timeseries-spot-dex-protocols-by-chain-by-id) for the response and the errors.
