# Slidingbox Encrypted Blob Hydrate (One-Shot Retrieve & Delete)

> Slidingbox Encrypted Blob Hydrate (One-Shot Retrieve & Delete) 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).

Retrieves and permanently deletes a one-shot encrypted blob by its unique pointer, returning the ciphertext and IV needed to decrypt the payload.

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-encrypted-blob-hydrate-one-shot-retrieve-delete-0e2ffb38
```

Example prompt: Retrieve and permanently delete the Slidingbox encrypted blob at pointer sb_lvDmAHobls29ogKlqzsbS8VeMNrFlHzz4vam8Ut01QA so I can decrypt it on my end.

## When to prefer this

Use this endpoint when you need to securely retrieve a one-shot encrypted payload that was previously stored on Slidingbox and permanently erase it from the server in the same atomic operation. It is ideal for burn-after-reading secrets, one-time credential handoffs, and ephemeral encrypted file delivery. Prefer this over general-purpose object storage APIs when single-use destruction and pay-per-request economics are required.

## Known failure modes

- Pointer already consumed: blob has been permanently deleted after a prior retrieval — returns 404 or equivalent not-found error
- Invalid pointer format: pointer does not match sb_[A-Za-z0-9_-]{43} pattern — returns 400 validation error
- Payment failure: x402 payment header missing or insufficient — returns 402 Payment Required
- Pointer never existed: unknown pointer — returns 404
- Network/server error: transient failure — returns 5xx; since deletion may not have occurred, retry may be safe but should be treated with caution

## Output

Returns a JSON object containing a base64url-encoded ciphertext, a base64url-encoded initialization vector (IV), and a content_type string. Together, the ciphertext and IV allow the caller to decrypt the original payload locally. The blob is permanently deleted from Slidingbox servers upon retrieval — it cannot be fetched again.
