Query Parameters
Maximum items per page (1-100). Accepted but currently ignored; no-op until this handler supports the parameter.
Cursor for next page. Accepted but currently ignored; no-op until this handler supports the parameter.
Optional area filter (e.g., "NAVAREA IV", "Persian Gulf").
Optional JMESPath expression applied server-side to project or reduce the JSON response before it is returned (mirrors the MCP jmespath argument). Invalid expressions, expressions larger than 1024 UTF-8 bytes, or projections that exceed the 256 KB output cap return HTTP 400 with a {_jmespath_error, original_keys} envelope. Grammar and worked examples: https://www.worldmonitor.app/docs/mcp-jmespath.
