Dtn Rate Limits
DTN does not publish numeric per-second/per-minute rate limits across its developer portal catalog. Effective limits are governed by the subscription tier and API key, and feed-style endpoints expect periodic (not high-frequency) polling aligned with the underlying data update cadence.

Subscription-bound API access api-key
see DTN subscription / contact sales
Endpoint scope (forecast horizon, observation retention) and effective rate are bound to the subscription tier.
Policies
Subscription Permissions
API key permissions vary with subscription tier; some endpoints (e.g. 15-day forecast) are gated by tier.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429/503 responses.
Polling Cadence
Forecast and observation endpoints update on a defined cadence; clients should align polling with the data update frequency rather than continuous polling.
