New Credit Costs

What are credits?

Credits are used to measure a user's consumption of node resources. We provide users with the corresponding monthly credit usage limit according to different plans. For more information about the monthly credit usage limits for different plans, see Plan Specifications.

Characteristics of credits

We set different credit consumption levels for resources consumed when a single call is made to each API method based on the resource type (computing resource and storage resource) and API complexity. Take Ethereum as an example, sending an eth_getBlockByHash request consumes 25 credits, and sending an eth_sendRawTransaction request consumes 200 credits.
In the future, we will support more vertical scenarios and data-based value-added services. Different services have different pricing for resource consumption. We will offer a reasonable price lower than the market price and provide pay-as-you-go pricing services.

Use limits of credits

Credit/s measures the number of credits used per second for making requests. Each RPC method is weighted differently. Credit/s is more efficient than counting only the number of requests sent per second in different use cases.
For example, for the provided Free package, there is a maximum limit on the number of credits consumed per second, with a maximum consumption of 400 credits per second.

Credit pricing details

Credits are organized into 9 tiers based on method complexity and resource consumption:

Key Changes:

• Simplified from complex pricing to 9 clear tiers
• Most users will see ~21% reduction in credit consumption

Note:

• All gRPC methods follow a fixed-rate billing model, with each call consuming 50 credits.
• The subscription service no longer uses tiered pricing based on data transfer volume. All gRPC method calls are charged at a flat rate of 50 credits per call, regardless of the data payload size. Currently, only SubscribeCheckpoints is supported. Each subscription call consumes 50 credits.

Bitcoin

Avalanche

Starknet

Solana

📘

Note:

Subscription/Unsubscription requests consume a fixed 30 Credits. Subsequent push message deliveries will consume additional Credits based on the size of each push message and the subscription type:

• If the pushed message is less than 500 bytes, each push will consume 5 Credits.
• If the pushed message is greater than 500 bytes: for blockSubscribe, each pushed message consumes 100 Credits; for other subscriptions, each pushed message consumes 35 Credits.

Webhook and WebSocket Subscriptions

The pricing for Webhook and WebSocket Subscriptions on ZAN Node is based on the amount of data delivered as part of the subscription, known as bandwidth.
Typically, a webhook or WebSocket subscription event contains around 1000 bytes of data, which would consume 40 credits.
However, it's important to note that this can vary depending on the specific event.
Each subscription type is priced identically per byte:

Note:

Unlike other blockchains, Solana has a unique Credits calculation method for WebSocket Subscriptions, as detailed in Solana's Credit pricing details.
