November 2022

DEX Liquidity & Events Dataset
Spice now features DEX Liquidity and Events Dataset where users can access indexed liquidity data from UniSwap [V2, V3] and SushiSwap liquidity pools, within seconds.
Data is available both historically and in real time, providing unparalleled visibility on DEX liquidity pools.
ENS (Preview) You can now preview the new dataset for Ethereum Name Service events, available by querying eth.ens. Within the dataset, you’ll find that each ENS event will have its own table as immutable data.
This also includes the new dataset, which is updated in real-time to have the latest eth_address whenever a transfer or name-registered event happens
Read more on the Spice AI blog.
  • Prices dataset now out of preview
  • Added export to CSV results format in addition to existing formats JSON and Apache Arrow, for easy use with apps, ML, or libraries like NumPy and Pandas
  • Added performance improvements for faster queries across existing datasets including eth.traces

October 2022

Spice now has prices dataset in preview.
  • Query historical High-Low-Open-Close (HILO) prices to minute precision
  • Join with other real-time and historical web3 data to do calculations and conversions back to USD
  • Initial data sources include Gemini, Coinbase, SushiSwap, and UniSwap (a mix of CEX, DEX, and third parties)

June 2022

This update includes a new Javascript/Typescript SDK for Node.js, an improved Python SDK, and performance improvements for Ethereum tokens and NFT datasets.
Ethereum Name Service (ENS) support is also available in beta with the new dataset.
Read more on the Spice AI blog.
  • Improved Python SDK
  • ENS support in beta
  • Improved performance for eth.tokens_ and eth.nft_ prefixed tables

May 2022

Spice now has some of the best automated token standard detection for erc20, erc721, and erc1155 tokens available. Tokens are detected by their signatures and as they emit events over time, so Spice provides a probability of standards compliance to each contract. Along with this support are now token-specific tables like eth.tokens_erc1155 and eth.token_transfers_erc20. See the entire list Tokens Tables.
Performance is now even better, especially for larger queries, and for results over the HTTP API. We still recommend the Apache Arrow Flight API that's easily accessible via the Python SDK for production use though.
WebSocket support is now available in private preview to Design Partners - get in touch if you are interested in custom limits, early access features, and dedicated support.


  • Improved Ethereum standard detection for erc20, erc721, and erc115 tokens
  • Added new token specific tables
    • eth.tokens_erc20
    • eth.tokens_erc721
