Object Storage API — free mock REST API for testing

Practice object metadata, base64 content, checksums, Range requests and resumable upload state.

The Object Storage API is a small S3-shaped surface: PUT an object, GET it back, and verify it. It is the only place in the catalog that serves HTTP 206 Partial Content for a Range request and 416 when that range cannot be satisfied — plus checksum validation and resumable uploads, the three things object-storage clients get wrong most often.

Base URL: https://funapi.dev/api/storage/v1 · 4 endpoints · OpenAPI 3.1 spec and Postman collection available. New here? Read the getting started guide.

What you can practise here

• Request a byte range and read the 206 together with its Content-Range header.
• Ask for a range past the end of the object and handle the 416.
• Upload with a deliberately wrong checksum and confirm the object is rejected, not silently stored.
• Start a resumable upload, interrupt it, and resume from the offset the API reports.
