# List observability runs

> Filterable run list via the contract's ``list_traces``, paged with the
reader's ``limit`` / ``page``. Time range plus the neutral advanced filters
(tags / status / cost / token / latency ranges) and sort.

List- or dict-typed query params are JSON-encoded in the query string
(``tags`` may be a JSON list ``["a","b"]`` or a comma-separated string).
