Wintel API – Asset Change Detection

Choose this endpoint when you need to detect and rank what has actually changed for a specific asset over a recent period, rather than getting a static snapshot of scores or a full AI narrative report. It is ideal for event-driven workflows, change monitoring pipelines, and alerting systems where you care about movement and delta rather than absolute values. Prefer it over the full AI analyst report endpoint when you need lightweight, fast signals rather than a full narrative, and over the score endpoint when you specifically want to know what changed, not just what the current score is.

• Invalid or unrecognized asset_id — returns 404 or empty result
• Payment not received or insufficient — x402 protocol returns 402 Payment Required
• Rate limit exceeded — too many calls in a short period
• No changes detected for asset in current period — returns empty changes array
