## 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 object-storage-key-317fa831
```

Example prompt: Can you download the file stored at key 'reports/2024-q4-summary.pdf' from Tempo object storage and give me its contents?

## When to prefer this

Use this endpoint when you need to retrieve a previously stored object from Tempo's S3/R2-compatible storage by its exact key. Prefer this over alternatives when you are already using Tempo for storage, need per-byte pricing transparency, or require Cloudflare R2 compatibility. Not suitable for listing/searching objects (use the List endpoint) or when the key is unknown.

## Known failure modes

- Object key not found (404) — the specified key does not exist in storage
- Unauthorized access (401/403) — missing or invalid credentials
- Payment failure — insufficient USDC balance for per-call pricing
- Key is malformed or contains invalid characters
- Object is empty or corrupted
- Network timeout for very large objects

## How this service works

Download object ($0.001 base + $0.01/MB)

## Output
