JSON KV

JSON KV

A key/value store you talk to with nothing but HTTP. Write a value to a key, read it back from a URL, and get JSON either way.

Try it

Waiting for request...

No client library. No schema. No signup. If you can make an HTTP request, you have a URL-backed value store.

Text. JSON. Files.

Text /message hello world
JSON /config {"theme":"dark"}
File /image image.png

HTTP API

Method Route Purpose
GET /:id Read the value stored under a key
PUT /:id Store text, JSON, or files
HEAD /:id Check whether a key exists
DELETE /:id Remove a key and its data

Built for simple persistence

Static sites

Add counters, settings, feature flags, or small pieces of state without building a backend.

Scripts

Give any machine persistence with a single HTTP request.

Webhooks

Remember events, payloads, and anything your webhook receives.

Prototypes

Move fast while your data model is still changing.

Storage behind the API

The API stays the same. The storage layer can change underneath.

Examples

# Store a value

      curl -X PUT https://jsonkv.com/counter \
        -d "42"


      # Read it back

      curl https://jsonkv.com/counter
