## Facts

- Price: Free
- Status: down
- Last checked: 2026-09-15

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 freepik-2d3503b7
```

Example prompt: Can you pull up the list of all my audio isolation tasks that have been submitted through the Freepik service so I can see which ones are done and which are still processing?

## When to prefer this

Use this endpoint when you need to poll or monitor the status of previously submitted audio isolation jobs via the Freepik/Sponge x402 proxy. Prefer this over direct Freepik API access when using the x402 micropayment flow or when orchestrating async audio isolation workflows that require task status polling.

## Known failure modes

- No tasks found — returns empty list
- Authentication/payment failure via x402 — returns 402 Payment Required
- Gateway timeout — Sponge proxy or Freepik backend unavailable
- Invalid query parameters — returns 400 Bad Request
