Limits

Per-Account Throttle api-key
varies
see Nasdaq Data Link operational guidance
Historical Quandl tiers were 50/day anonymous and up to 50,000/day authenticated; current Nasdaq Data Link numbers must be re-verified in the docs portal before use.

Policies

Authentication Required
Anonymous access is heavily throttled; authenticated requests using a Nasdaq Data Link API key receive substantially higher quotas.
Backoff Strategy
Clients should apply exponential backoff with jitter when receiving 429 responses; premium dataset entitlements are enforced separately from request-rate throttling.
