FAQ

When should I choose a credit-based model over a subscription?

If you need AIS data on a regular, ongoing basis, a subscription plan is typically more cost-effective. If your usage is occasional or ad hoc, the credit-based model offers greater flexibility and can be more economical.

How frequently is position data updated?

Position data is refreshed every few seconds. However, not every vessel will transmit a new position in each update cycle — the frequency depends on the vessel’s movement and AIS transmission behavior.

How often can I make API requests?

• Credit-based services: You can make requests as often as needed. You are only charged for the data returned.
• Subscription-based services: Request frequency depends on your specific subscription agreement.
