GET`/api/v1/market-intelligence/deltas`

Get Deltas

Incremental delta endpoint - frontend polling 15-30s pattern. SCAFFOLD : returns empty delta list. Real implementation will query `screener_asset_latest WHERE updated_at > :since LIMIT 200` and emit only changed fields (compact payload ~160 bytes/asset). Anti-pattern interdit (brainstorm §5.6) : PAS de SSE Top 200 global push 5s pour 1K users (fragile FastAPI sans Redis). Polling 15-30s suffit au MVP.

Authentication

This endpoint requires the X-API-Key header or a valid Clerk JWT. Accepted schemes: APIKeyHeader, HTTPBearer.
