Alpha Vantage Rate Limits
Alpha Vantage limits its free tier to 25 API requests per day and 5 requests per minute. Premium tiers raise the per-minute cap to 75, 150, 300, 600, or 1,200 requests per minute (no daily cap). Throttled requests return a JSON body with Note or Information indicating the limit, rather than HTTP 429.

Soft Throttling
Throttled responses return HTTP 200 with a JSON body containing a Note or Information field; clients must inspect the body, not just the status code.
Backoff Strategy
Implement exponential backoff with jitter when Note/Information is returned.
