Why it shows up like this
Unreviewed registry note: When you notice an entry labeled as LANGSMITH* OBSERVABILITY on your credit card or bank statement, it represents a payment made to LangChain Inc. for LangSmith. This platform serves software engineers and artificial intelligence developers by providing comprehensive tools for tracing, evaluating, debugging, and testing large language model applications.
Unreviewed registry note: This charge typically appears because you or a member of your development team registered for a paid subscription tier, such as the Developer plan, or incurred usage overages beyond the free monthly trace limit. Because AI applications log thousands of execution runs, prompt inputs, and token latencies, automated billing cycles frequently renew monthly on saved payment credentials.
