# List traces

`POST /api/traces/list/`

Retrieve a paginated list of traces matching your filters. Supports the filter payload documented in the Filters API. Metadata keys beginning with `_` are reserved for platform use and are omitted from customer-facing span and trace responses, so they do not round-trip through read APIs.
