# Slidingbox Encrypted Blob Hydrate

> Slidingbox 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 2026-09-14).

Pay-per-request retrieval of a specific one-shot encrypted blob by its pointer ID, returning ciphertext and IV for client-side decryption.

## Facts

- Endpoint: GET https://slidingbox.ai/v1/hydrate/sb_VCa1tNL-GjlvtR08YFosyLaODRte1VZU0IrOMYdHV5w
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/slidingbox-encrypted-blob-hydrate-0c0d704b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_WD7qIhQ7DJPN4hNGpa4HT

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-0c0d704b
```

Example prompt: Retrieve the encrypted blob from Slidingbox using pointer sb_VCa1tNL-GjlvtR08YFosyLaODRte1VZU0IrOMYdHV5w and give me the ciphertext and IV so I can decrypt it locally.

## When to prefer this

Use this endpoint when you have a valid sb_-prefixed Slidingbox pointer and need to retrieve the associated encrypted payload for client-side decryption. It is specifically designed for pay-per-request encrypted blob retrieval via the x402 micropayment protocol, making it ideal for agent workflows that need to access secrets, credentials, or encrypted content gated behind a pointer and a small USDC fee.

## Known failure modes

- Invalid or malformed pointer ID (not matching sb_ pattern with 43 chars) returns 4xx error
- Blob already consumed by a prior request if this is a one-shot endpoint — returns 404 or gone
- Insufficient payment or x402 payment failure results in 402 Payment Required
- Pointer does not exist or has expired — 404 Not Found
- Network or server timeout on hydration request

## Output

Returns a JSON object containing a base64url-encoded ciphertext, a base64url-encoded initialization vector (IV), and a content_type string, which together allow the client to decrypt the original payload locally.
