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 2s-io-blob-store-get-download-blob-eab1135d -d '<json body>'
```

Example prompt: Fetch the blob with key 'user-report-2024' from the 'analytics' namespace in the 2s.io blob store.

## When to prefer this

Use this endpoint when you need to retrieve a blob that was previously stored in the 2s.io blob store using a known namespace and key. Prefer this over generic storage APIs when you are already working within the 2s.io ecosystem and paying per-call with USDC via x402, with no signup or API keys required.

## Known failure modes

- Blob not found — the namespace or key does not exist, likely returns empty or error response
- Incorrect namespace — blob stored in different namespace won't be returned
- Payment failure — insufficient USDC balance or x402 payment not processed
- Malformed request — missing required 'ns' or 'key' fields

## How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

## Output

Returns the blob data (arbitrary JSON object) stored under the given namespace and key, or an empty object if not found. The response schema is an open JSON object whose contents depend on what was originally stored.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "ns": {
   "type": "string",
   "description": "Namespace the blob lives in."
  },
  "key": {
   "type": "string",
   "description": "Key to download."
  }
 }
}
```
