🚨 API v2 – Breaking Changes in Release 9.1.0

New fields have been introduced in several REST API response objects:

Token Transfer → new token_type field (ERC-20 / ERC-721 / ERC-1155 / ERC-404)
Transaction → new is_pending_update flag (true / false)
Block → new is_pending_update flag (true / false)
Address, Token → new reputation field (null / ok / scam)
Smart Contract → new conflicting_implementations field

Removed Endpoints

Public tags - related endpoints have been removed:
- /api/v2/user/public_tags
- /api/v2/user/public_tags/:id - /account/public_tags_request

🚨 Breaking Changes in the JSON RPC API

txlist endpoint → new methodId field has been added to the response
