What is Keyvalue?
Keyvalue is a minimal REST API that stores and retrieves data using key-value pairs without additional features or configuration.
It supports developers who need lightweight, temporary storage during early-stage application prototyping and testing.
What you can build with Keyvalue
Prototype session storage
Quickly persist user session tokens or flags across stateless serverless functions during early app testing without setting up a database.
Temporary config sharing
Store environment-specific configuration values that multiple team members or services can read while iterating on a new feature branch.
Lightweight feature flags
Toggle experimental features on or off by updating simple key values, allowing instant changes visible to all prototype clients.
Get started with Keyvalue
- 1Send a POST request to the store endpoint with your key and value in the JSON body
- 2Use a GET request with the key in the path to retrieve the stored value
- 3Issue a DELETE request to remove a specific key when no longer needed
- 4Check the API root or /docs endpoint for the exact URL structure and response formats
- 5Integrate the calls directly into your prototype code using any HTTP client
