Both ``from_ts`` and ``to_ts`` are required. A reversed time window (``from_ts`` after ``to_ts``) is rejected with 422. The underlying scan is capped at 50,000 matching spans, so metrics over a very large window may be based on a truncated set. Results are narrowed to traces the caller is authorized to read. ## OpenAPI ````yaml https://api.sgp.scale.com/openapi-versions/v5/openapi.json post /v5/spans/metrics openapi: 3.1.0 info: title: EGP API V5 description: >- This is the parent API for all EGP APIs.

Multiple terms are ANDed, and UUID-shaped terms match trace IDs instead. Substring means mid-word fragments match, while an inflected form such as a plural matches only where it appears literally. A span must match every non-UUID term, and each term may match any of the searched fields. UUID matches are ORed onto the text match. Each term must be at least 2 characters. For exact trace ID lookup, use the `trace_ids` filter. Accounts still served by the legacy trace store match differently until migrated: terms match as stemmed whole words rather than substrings, only input and output are searched, the 2-character minimum is not enforced, and characters like `:`, `|`, or `!` inside a term may be interpreted as query operators or cause an error. items: type: string type: array extra_metadata: title: Extra Metadata description: Filter on custom metadata key-value pairs additionalProperties: true type: object application_variant_ids: title: Application Variant Ids description: Filter by application variant IDs items: type: string type: array assessment_types: title: Assessment Types description: Filter to spans that have at least one assessment of these types items: type: string type: array acp_types: title: Acp Types description: Filter by ACP types items: type: string type: array agentex_agent_names: title: Agentex Agent Names description: Filter by Agentex agent names items: type: string type: array agentex_agent_ids: title: Agentex Agent Ids description: Filter by Agentex agent IDs items: type: string type: array min_duration_ms: title: Min Duration Ms description: >- Minimum span duration in milliseconds (inclusive).
