Dnv Rate Limits

DNV does not publish per-second/per-minute rate limits for its Maritime customer APIs. Access is gated by a signed API contract and OAuth 2.0 client credentials issued via Azure AD B2C. Access tokens are valid for ~20 minutes and should be reused across requests. Effective limits are governed by the contract and fair-use review.

Effective limits are governed by the contract. No public RPS/RPM numbers are published.

Policies

Token Reuse
OAuth 2.0 access tokens (Azure AD B2C) are valid for ~20 minutes and should be reused across HTTP requests rather than re-acquired per call.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429/503 responses.
Contracted Access
A DNV API contract must be signed; the named technical contact receives client_id / client_secret.
