Build chart-ready EVM OHLC candles plus a recent trade tape from supported DEX event sources, including Uniswap v2-style swaps, Uniswap v3/v4, and Aerodrome Slipstream.
COMMON USER ASKS:
- Base Uniswap v2-style swap candles
- Base Uniswap candles
- Base Uniswap v4 candles
WHEN TO USE:
- You need OHLC candles for supported EVM event-derived price sources.
- You want a candle chart and recent trades instead of scalar time-series buckets.
- You want a Dexscreener-style pool chart with hover-ready candle metadata and a trade tape.
DON'T USE:
- You only need counts or scalar metrics over time.
- You want a simple activity chart for a network rather than pool candles.
EXAMPLES:
- Base Uniswap v2-style swap candles: {"network":"base-mainnet","source":"uniswap_v2_swap","pool_address":"0x<pool-address>","duration":"1h","interval":"5m","price_in":"auto","include_recent_trades":true}
- Base Uniswap candles: {"network":"base-mainnet","source":"uniswap_v3_swap","pool_address":"0x<pool-address>","duration":"1h","interval":"5m","price_in":"auto"}
- Base Uniswap v4 candles: {"network":"base-mainnet","source":"uniswap_v4_swap","pool_id":"0x<pool-id>","duration":"1h","interval":"5m","price_in":"auto","include_recent_trades":true}
- Base Aerodrome Slipstream candles: {"network":"base-mainnet","source":"aerodrome_slipstream_swap","pool_address":"0x<pool-address>","duration":"1h","interval":"5m","price_in":"token1"}
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| network | string | no | EVM network name (default: base-mainnet) |
| pool_address | string | no | Pool/pair contract address for address-keyed sources like Uniswap v3, Slipstream, or Sync-derived CPMM pools. |
| pool_id | string | no | Uniswap v4 pool id (bytes32). Optional when you provide the full v4 pool key instead. |
| pool_manager_address | string | no | Uniswap v4 PoolManager address. Optional on networks with a built-in official Uniswap deployment mapping. |
| source | string | no | Which event source to build candles from. Prefer swap-derived sources for factual trade prices and volumes. Uniswap v4 uses PoolManager Swap events filtered by pool_id, not a per-pool contract address. |
| interval | string | no | Candle interval. auto uses chart-friendly defaults like 1h→5m and 24h→1h. |
| duration | string | no | How much recent history to cover. Accepts compact durations like "1h" or natural phrases like "past 30 minutes". |
| mode | string | no | Execution depth. Defaults to complete requested-window analysis; the optional fast value is only for explicitly bounded previews. |
| price_in | string | no | Choose which token the displayed price should be expressed in. auto picks the more human-readable quote side. |
| base_token | string | no | Legacy orientation input. Prefer price_in instead. |
| include_recent_trades | boolean | no | Include a recent trade tape for swap-derived sources when factual per-trade amounts are available. |
| recent_trades_limit | integer | no | Maximum number of recent trades to return in the trade tape. |
| currency0_address | string | no | Optional Uniswap v4 currency0 address. Use with currency1_address, fee, and tick_spacing to derive pool_id factually. |
| currency1_address | string | no | Optional Uniswap v4 currency1 address. Use with currency0_address, fee, and tick_spacing to derive pool_id factually. |
| fee | integer | no | Optional Uniswap v4 LP fee in hundredths of a bip, e.g. 3000 for 0.30%. |
| tick_spacing | integer | no | Optional Uniswap v4 tick spacing. Required with the rest of the pool key when deriving pool_id. |
| hooks_address | string | no | Optional Uniswap v4 hooks contract address. Defaults to the zero address when omitted. |
| token0_symbol | string | no | Optional token0 symbol label for summaries |
| token1_symbol | string | no | Optional token1 symbol label for summaries |
| token0_decimals | number | no | Optional token0 decimals for human-readable prices |
| token1_decimals | number | no | Optional token1 decimals for human-readable prices |
| token0_address | string | no | Optional token0 address to infer known decimals |
| token1_address | string | no | Optional token1 address to infer known decimals |
| cursor | string | no | Continuation cursor from a previous candle page |
