238264 Exported spans aren’t guaranteed to be a complete record of your API usage. Their delivery is [best effort](https://platform.claude.com/docs/en/manage-claude/opentelemetry/api#delivery-and-health), so a span can be lost. A caller can also leave out a request’s spans by turning off the sampled flag in the request’s [`traceparent` header](https://platform.claude.com/docs/en/manage-claude/opentelemetry/api#connect-api-spans-to-your-own-traces). To track each API key’s usage, for example to spot a leaked key, use the [Usage API](https://platform.claude.com/docs/en/manage-claude/usage-cost-api#usage-api), which also counts the usage of requests without spans.
