We use a credits system for enforcing limits and metering usage.

Every request you make has a cost stated in the credit schedule on our [pricing page](/pricing/). Most endpoints are charged per request. The Time/Distance Matrix API is charged per element, so its cost scales with the size of the matrix.

These are counted against your plan's monthly credit allowance and, if you have opted in to additional usage, billed at the rate specified in your plan once you exhaust your credit pool.
