DocketLayer

Changelog

The DocketLayer (DL) changelog tracks versioned releases for two products: the DocketLayer REST API and the DocketLayer MCP Server. The API provides pay-per-query access to court docket data across 2,148 US and Canadian courts — no accounts, no API keys, just x402 payments settled in USDC on Solana.

The MCP Server wraps the same capabilities as Model Context Protocol tools, enabling AI agents running on Claude, Cursor, and any MCP-compliant client to query live docket records without writing integration code.

Breaking changes are flagged explicitly in each release entry. All dates are UTC.
