# SlidingBox One-Shot Encrypted Blob Hydrate

> SlidingBox One-Shot Encrypted Blob Hydrate is a paid API for AI agents from slidingbox.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Retrieves and permanently deletes a one-shot encrypted blob using a pointer, invalidating the pointer immediately upon success.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability slidingbox-one-shot-encrypted-blob-hydrate-0c0b8292
```

Example prompt: Retrieve the one-shot encrypted secret stored at the SlidingBox pointer sb_o41Tn-c8uC3aOlG8peCg1tpcAThSziqrv5x3qKjOadY — it's a burn-after-reading blob, so fetch it now and show me the contents before the pointer gets invalidated.

## When to prefer this

Use this endpoint when you need to retrieve a secret or payload that must be destroyed immediately after a single read — such as burn-after-reading messages, one-time credentials, or ephemeral configuration. This is specifically suited for scenarios where the non-repeatability guarantee is a security requirement. Prefer this over general blob storage retrieval when the one-shot deletion semantic is essential and when the x402 pay-per-request model fits your cost structure.

## Known failure modes

- 404 if the pointer has already been consumed (even on a previously paid call)
- 404 if the pointer never existed or was mistyped
- Payment failure via x402 protocol if USDC balance is insufficient
- Network timeout if the service is temporarily unavailable
- Pointer invalidated mid-request if a race condition occurs with a concurrent hydrate

## How this service works

Pay per request (x402) to retrieve and permanently delete a one-shot encrypted blob by pointer. The pointer is invalidated the instant this call succeeds; a second hydrate against the same pointer always 404s, paid or not.

## Output

Returns the decrypted contents of the one-shot encrypted blob associated with the given pointer. Upon a successful response, the pointer is permanently invalidated and any subsequent request to the same pointer will return a 404, regardless of payment. The response is the raw blob payload.
