Spans

Get a span within a trace

Retrieve the full span payload using its complete trace-scoped identity.

Use this endpoint when both identifiers are known; GET /v5/spans/ remains available for callers that have only a span id. Reads use the account’s configured source, the legacy trace store or the tracing service, with fallback to the legacy trace store outside strict mode. Access is authorized against the trace, and an unknown span or a span belonging to another trace returns 404. input_tokens and output_tokens carry the token usage the span’s producer reported at ingest, and are absent both for a span that reported none and for every span served from the legacy trace store, which keeps no token counts.
