}FAQ
01
What is seekdb.D0?
seekdb.D0 is a free trial entry point for seekdb. No signup, no setup — create a real, MySQL-compatible seekdb database instance via API. Ideal for developers and teams looking to evaluate features, validate prototypes, follow tutorials, or run demos.
02
Do I need to sign up or add a credit card?
No. Create an instance via the API and get a ready-to-use connection string immediately — no account or payment details required.
03
How do I create and use an instance?
Use POST https://d0.seekdb.ai/api/v1/instances to create a new instance. Once created, you receive a connection string and can connect over MySQL/TLS to start running SQL immediately.
04
What are the usage limits and TTL?
Each instance has a hard spending limit of $0.20 and lasts up to 7 days. When it expires, credentials are revoked and the database is securely deleted.
05
What are seekdb's core capabilities?
seekdb supports hybrid search (vector search + full-text search + relational queries), multiple vector index types, multi-model data (relational / vector / full-text / JSON / GIS), and in-database AI functions (AI_EMBED, AI_COMPLETE, AI_RERANK, etc.). In D0 trial instances, AI functions are disabled for security reasons.
06
How do I fork a table or instance?
Table fork: Run FORK TABLE source_table TO destination_table; directly in the database to create an independent copy based on a consistent snapshot. Reads and writes to either table do not affect the other.
Instance fork: Call POST https://d0.seekdb.ai/api/v1/instances/{id}/fork to fork an existing instance into an independent new instance. A successfully forked instance receives a new 7-day TTL.
Note: In D0 trial instances, forking may fail due to resource limitations.
07
Can I use it for AI agent memory?
For persistent AI agent memory, we recommend using seekdb.M0 (https://m0.seekdb.ai).
08
Data security and service guarantees
Data is stored in data centers in Singapore or Kuala Lumpur. Instances are fully isolated from each other. Connections are encrypted via TLS, and data is securely deleted after expiration. If your data is subject to regulations such as GDPR, please assess compliance on your own and avoid storing regulated sensitive data in trial instances. seekdb.D0 is a free trial service with no SLA guarantees and no liability for data loss or service interruptions. It is not recommended for production data.
09
What is the relationship between seekdb.D0 and seekdb?
seekdb is an open-source project (https://github.com/oceanbase/seekdb). seekdb.D0 is its free trial experience. For long-term use or full functionality, please follow the seekdb open-source community and official releases. Note: documentation and community discussions may appear in both Chinese and English. If you find seekdb useful, please consider giving it a ⭐ on GitHub — it really helps!
