# SlidingBox One-Shot Encrypted Blob Retrieval

> SlidingBox One-Shot Encrypted Blob Retrieval is a paid API for AI agents from slidingbox.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Pay-per-request retrieval and permanent deletion of a one-shot encrypted blob identified by a unique pointer; the pointer is invalidated immediately upon successful retrieval.

## Facts

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-retrieval-8aa4eb42
```

Example prompt: Retrieve the one-shot encrypted blob at pointer sb_ABxOJfI5tlsb4jqNcUe7rTkJ1ZIfgRUr-XSDpPeXwvw from SlidingBox — pay the $0.02 USDC request fee and give me the ciphertext, IV, and content type so I can decrypt it locally.

## When to prefer this

Use this endpoint when you need to retrieve a secret or payload that was intentionally stored as a one-time-use encrypted blob — meaning it should be destroyed the moment it is read. Ideal for one-time password delivery, ephemeral key exchange, single-use credential handoff, or any scenario where the sender explicitly wants the data to be unrecoverable after the first read. The x402 pay-per-request model and irreversible pointer invalidation make it unsuitable for repeated reads of the same data.

## Known failure modes

- 404 Not Found — pointer has already been consumed or never existed; no refund on subsequent calls
- Payment failure — x402 payment not accepted or insufficient USDC balance; blob not returned
- Network timeout — blob not delivered but pointer state may be ambiguous
- Invalid pointer format — malformed sb_... identifier returns error
- Service unavailable — blob store temporarily unreachable

## 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 a JSON object containing: ciphertext (base64url-encoded encrypted payload), iv (base64url-encoded initialization vector for decryption), and content_type (MIME type of the original content). The pointer is permanently invalidated after this call — any subsequent request to the same URL will return a 404 regardless of payment.
