Account & Login

A: Please make sure there are no extra spaces before or after your username or password.
If you need to reset your password, please contact BD. Q: On subsequent logins, I forgot my password or received an incorrect password error. What should I do?
A: Please make sure there are no extra spaces before or after your username or password,
or click “Forgot Password” to reset it.

​
Account & Billing

Q: Will the service stop immediately if my account is overdue?
A: Once your account is overdue, API requests will not return results.
We will send balance reminders and notify you in the group chat.
If you have confirmed your purchase but payment is delayed,
we can arrange a small top-up to keep your business running without interruption. Q: Are all API calls charged at the same rate?
A: All single calls have the same unit price. For batch calls,
the cost depends on the number of addresses you submit.
For example, submitting 50 addresses in one batch equals 50 single calls. Q: Can I set a limit for my API key?
A: No, each account has a single API key, and the quota cannot be split.

​
API Access & Security

Q: If I don’t set an IP whitelist, can any IP access the service?
A: No. You must configure an IP whitelist. If it’s not set,
the API will return an unauthorized message. Q: Where is the Bitrace service hosted?
A: In Hong Kong.

​
API Performance & Capacity

Q: Can you provide API performance metrics (SLA)?
A: Please refer to the SLA documentation.
Key metrics include:
  • Availability: Calculated based on HTTP status codes (e.g., 5xx), excluding planned maintenance
  • Performance: 95% of requests respond within ≤ 500ms, actual speed may vary due to transaction volume, chain depth, and real-time processing
  • Incident Handling: P1 incidents resolved within 1 hour, P2 incidents within 4 hours
Q: What are the API capacity and security limits?
A:
  1. QPS limit: 100 QPS (per IP + API), based on token bucket algorithm
  2. Daily call limit: 100,000 calls/day (calculated by calendar day)
  3. Over-limit requests will return HTTP 429 (Too Many Requests)
Q: How long does it take to get asynchronous results for kya-api-getriskscore?
A:
  • Average response time: under 2 seconds
  • Maximum response time: less than 10 seconds
  • Factors affecting response speed:
    1. Querying an address that interacts with a very large set of other addresses
    2. Service overload and task queue backlog
