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.

Alpha Vantage Rate Limits is the machine-readable rate-limit profile for Alpha Vantage on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 7 rate-limit definitions, measuring requests_per_day and requests_per_minute.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Policies

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.
