# Slidingbox Hydrate — One-Shot Encrypted Blob Retrieval

> Slidingbox Hydrate — 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 2026-09-15).

Retrieves and permanently deletes a one-shot encrypted blob by pointer; the pointer is invalidated immediately on success, making this a single-use read operation.

## Facts

- Price: $0.02/call
- Payment: x402

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-hydrate-one-shot-encrypted-blob-retrieval-8870f94d
```

Example prompt: Retrieve the one-shot encrypted blob at pointer abc123xyz on Slidingbox — consume it now and give me whatever's inside; it'll self-destruct the moment you read it.

## When to prefer this

Use this endpoint when you need to securely retrieve a secret, credential, or sensitive payload that must be provably destroyed after a single read — such as burn-after-reading messages, one-time passwords, or ephemeral handoff tokens. Prefer this over standard secret stores when the key guarantee is that no second retrieval is possible, not even by the sender.

## Known failure modes

- Pointer already consumed: returns 404 because the blob was already retrieved and deleted
- Invalid or malformed pointer: returns 404 or 400 if the pointer string is not recognized
- Payment failure: x402 payment not accepted or insufficient, access denied
- Network timeout: blob not returned, but pointer invalidation state may be ambiguous
- Blob never existed: pointer references a payload that was never stored, returns 404

## 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 encrypted blob associated with the given pointer. After a successful retrieval, the pointer is permanently invalidated and any subsequent call with the same pointer returns a 404. The response contains the stored payload data.
