Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent product update. Have there been any significant changes to the API or related systems in the past month?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, a minor update was pushed two weeks ago. Impact on approach: If confirmed, we'd focus on that update as a primary suspect.

• Considering user segments, I'm curious if this decline is uniform across all clients. Can you provide a breakdown of the API usage decline by client type or industry?

Why it matters: Segmented data helps identify if the issue is global or specific to certain users. Expected answer: The decline is more pronounced in the financial services sector. Impact on approach: We'd investigate sector-specific factors and tailor our solution accordingly.

• Given the nature of financial data, I'm wondering about any recent market events. Have there been any major financial news or market shifts that could impact the demand for our data?

Why it matters: External events can significantly influence financial data consumption. Expected answer: No major market events, but there's been a slight downturn in fintech investments. Impact on approach: We'd consider market trends as a contributing factor, but not the sole cause.

• Thinking about system health, I'm concerned about potential technical issues. Have we observed any unusual error rates or performance metrics in our API infrastructure?

Why it matters: Technical problems can directly impact API usage. Expected answer: Error rates have remained stable, but there's been a slight increase in response times. Impact on approach: We'd investigate the performance degradation as a possible contributor to the usage decline.
