Marine Traffic Rate Limits

Reconciled rate-limit and quota policy for the MarineTraffic AIS Data API. Unlike per-second token-bucket APIs, MarineTraffic primarily meters by credits-per-row against a prepaid credit balance, layered with a per-service refresh interval ("call frequency") that defines how often a given vessel / fleet / port can be re-queried before responses are served from cache.

Marine Traffic Rate Limits is the rate-limit profile for MarineTraffic on the APIs.io network.

The provider publishes no rate limits that could be read; the profile records that absence rather than inventing a ceiling.

An exhausted limit returns HTTP 429.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, notEnoughCredits, unauthorized, and badRequest.

Tagged areas include Maritime, AIS, Quotas, and Credits.

Policies

Cache-aware billing
Repeat requests inside the refresh window are served from cache and do NOT decrement credits.
Live vs delayed AIS
Default AIS feed is delayed by 1 hour. Real-time (1-minute) AIS access is a premium contract upgrade.
Pre-purchase credits
Buy credits in advance to absorb usage spikes — there is no monthly auto-throttle once credits are exhausted.
