Release Notes

4 March 2026

Added search filters to GET /v2/transactions: filter by token symbol (t, repeatable), transaction category (cf), DeFi protocol (p), and transaction hash (h). Added sort (date, value, fee) and order (asc, desc) parameters. When h is provided, all other filters are ignored.
Added GET /v2/transactions/date-bounds endpoint — returns the earliest and latest transaction dates in the portfolio, useful for constructing date-filtered queries.
Added GET /v2/transactions/metadata endpoint — returns available DeFi protocol names for the portfolio, useful for discovering valid p filter values.
MCP Server updated to v1.1.0: added node40_get_transaction_date_bounds and node40_get_defi_protocols tools; updated node40_search_transactions with new filter parameters.

Added subType field to the V2 transactions response.
MCP server is now available on npm as @node40/mcp-server. Using npx is now the recommended setup method — it keeps your server automatically up to date as new tools are added. See the MCP Server page for updated configuration instructions.

Added MCP Server for AI agent integration (Claude Code, Claude Desktop).
Redesigned docs with modern sidebar navigation.
Added dedicated API Clients and MCP Server pages.
Updated all code examples to current V2 endpoints.
Added complete Node.js and Python request-signing examples.
Added downloadable Postman and Insomnia collections with automatic request signing.
Added deprecation notice for V1 endpoints (sunset 2026-06-30).

Added optional lastModifiedDate parameter to the timeline endpoint, enabling retrieval of transactions modified from a specified date onward (including deleted transactions).

Added sourceGuid to the source field in the timeline response. This identifier remains stable for a given ledger's source.
