• [NEW] Transfer Insights endpoints now allow filtering by transaction type label (mint, burn, sale, transfer). In addition, these endpoints now return a list of the transaction type labels associated with the transfer for both Ethereum and Polygon. With this update, we have soft-deprecated the transferType attribute on the Transfer Insights endpoints.

• [NEW] Owners count by contract endpoint has been released for Polygon

• [NEW] Transfer Insights endpoints have been released for both Ethereum and Polygon. Check our migration guide with comparison of Transfer Insights to the old Transfers endpoints.
• Along with this release, we have soft-deprecated old Transfer endpoints. We remain committed to our promise of backwards-compatibility and will continue supporting the deprecated endpoints until all clients fully migrated.

• Collections API and Pricing API aggregative endpoints now allow to group data by 15 minutes chunks. Full list of improved methods include:
  • Collections API / Owners count by contract
  • Collections API / Token supply by contract
  • Pricing API / Prices by contract
  • Pricing API / Sales volume by contract

Top collections by X endpoints now returns contract_name in addition to the address. Contract name (a.k.a collection name) is derived from the name() method of each contract on the blockchain.

[NEW] Polygon APIs are released.

• Transfer responses now contain all fungible transfers from the same transaction, which enables a more accurate NFT price estimation.
• eth_transfers is introduced in the GetTransfersBy* responses. Read more in the Advanced Transfers documentation.
• nft_transfers_quantity field in the GetTransfersBy* responses is soft-deprecated in favor of a more detailed breakdown of all transfers within the same transaction. Read more in the Advanced Transfers documentation.

• types field is added in the GetContractDetails response and request to enable filtering by multiple types to support polymorphic contracts.
• type field in the GetContractDetails response is soft-deprecated in favor of polymorphic contracts implementing multiple types.

• [NEW] Collection Analytics and Pricing APIs are released. Read more at https://www.mnemonichq.com/blog/mnemonic-ga-launch.
• block_number field in the MintEvent of the GetTokensByContract and GetTokensByMinter endpoints is soft-deprecated in favor of tx_hash, log_index and block_timestamp.

• Added new endpoint GetTokensByMinter. This endpoint simplifies the search for the creator of a specific collection.
• Added block_timestamp_gt filter in the GetTokensByMinter, which allows filtering by minimal block timestamp, using "greater" comparison. This filter exludes rows matching given timestamp exactly.
