Query Parameters
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.
Response
Successful response
True when the seeded snapshot or release calendar is unavailable; callers should render the response as degraded rather than treating it as current.
