Guide to buying credits and understanding SonJJ's credit system

In this article, we will guide you on how to purchase credits from the system wallet, explain in detail the credit calculation mechanism for each type of API request, and share cost optimization strategies.

1. Introduction to SonJJ's credit system

SonJJ's credit system is the main payment unit for all API requests. This is one of the most outstanding features of SonJJ compared to other API services in the market:

• Credits never expire - You can buy and use them anytime, without worrying about usage time limits
• Charges only on success - Credits are only counted when the request returns status code 200
• Fair cost - Each type of endpoint has a different cost, reflecting the actual value it provides
• Attractive bonuses - Save up to 35% when buying larger credit packages

"Credits do not expire. And it comes in cheap, if you buy larger plans."

2. Simple guide to creating an API Key

You just need to log in to the system management area through this link https://my.sonjj.com/. Then you only need to select the menu item named API

You will see a button called "Change API KEY", click on it and you will get an API Key to use.

3. In the "Buy Credits (does not expire)" section, choose the credit package that fits your needs
4. Click on the "Buy Now" button

Saving tip: If you plan to use the API for a long time, choosing Plan-3 with a 35% bonus will help you save significant costs. With 133,650 credits (including bonus), you can make millions of requests to low-cost endpoints.

4. Credit calculation mechanism for each API request

SonJJ applies a smart credit calculation mechanism: only counting credits for successful requests (returning status_code=200). This ensures you only pay when you actually receive value from the API.

"Cost of each successful request (status_code=200)"

Credit costs are allocated based on the value and complexity of each endpoint:

Explaining cost differences

There are clear differences in costs between endpoints:

• Simple endpoints (0.05 credits): Inbox query endpoints have the lowest cost due to simple processing
• Standard endpoints (1-2 credits): Message, list, and create endpoints have average costs
• Complex endpoints (>10 credits): Endpoints like check_index have the highest cost (14 credits) due to their high value and complex processing

Special note: Costs will vary between plan packages. The above pricing applies to PLAN-1. With higher packages that include bonuses, the actual cost for each request will be lower.

5. Benefits of SonJJ's credit system

SonJJ's credit system brings many benefits to users:

Fair cost

You only pay based on the actual value received. Simple endpoints have low costs, while endpoints providing higher value will have correspondingly higher costs. This ensures a balance between cost and benefit.

Easy budget forecasting

With fixed credit costs for each type of request, you can easily estimate the API budget for your project. For example, if you know you will make 1,000 requests to the inbox endpoint daily, you will spend 50 credits/day (1,500 credits/month).

Savings with scale

The more credits you buy, the more you save. With the 35% bonus from Plan-3, the actual cost for each request will decrease significantly. This is a major advantage for businesses using the API with high frequency.

No worries about deadlines

Credits never expire, allowing you to buy in large quantities to take advantage of bonuses without worrying about having to use them all within a specific time period.

6. API cost optimization strategies

To optimize costs when using SonJJ's API, you can apply the following strategies:

Choose low-cost endpoints when possible

For example, if you only need to check if there are new emails, use the /inbox endpoint (0.05 credits) instead of /message (1-2 credits). Only use expensive endpoints when absolutely necessary.

Focus on credit packages with high bonuses

Plan-3 with a 35% bonus will help you save significant costs in the long run. Instead of buying Plan-1 multiple times, consider investing in Plan-3 from the start.

Optimize API call frequency

Instead of calling the API continuously, set up reasonable intervals between calls. This not only saves credits but also reduces load on your system.

Cost optimization example:

A company needs to check 10,000 emails monthly:

• Option 1: Using Single API /v1/check_index (14 credits/request) = 140,000 credits/month
• Option 2: Combining inbox checks (0.05 credits) and only using message checks (1 credit) when needed = ~20,000 credits/month

→ Savings: 120,000 credits/month (equivalent to over $120 with Plan-1)
