Query Parameters

jmespath
string

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.

unavailable
boolean

True when the upstream or seed-backed variant is unavailable; empty payload fields are graceful degradation, not confirmed zero data.

stale
boolean

True when latest_date is older than the CISS content-age budget -- the ECB series has stopped publishing (issue #3845). Consumers must not present a stale reading as current. Seeder-side detection is content-age (STALE_CONTENT in /api/health); this flag is the per-request equivalent.
