Insight API: Unified Token Transfers with Metadata

Arsenii

We’ve improved the Insight API to support unified access to all token transfers — both NFTs (ERC721/ERC1155) and fungible tokens (ERC20) — through a single, consistent endpoint 🚀

• You can now fetch NFT and ERC20 transfers in one call.
• Transfer responses include metadata for both NFTs and ERC20 tokens.
• Added support for a new "burn" transfer type when tokens are sent to the zero address.
• Introduced filtering by token type (erc20, erc721, erc1155) via query parameters.

This change simplifies integration and improves performance when querying mixed token transfers — especially useful for clients who need a single endpoint to track all token activity.
