## 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 quantaflow-x402-gateway-instagram-stories-videos-downloader-73a67067 -d '<json body>'
```

Example prompt: Download the Instagram story or video at this URL for me: https://www.instagram.com/stories/someuser/1234567890/ — use the QuantaFlow x402 gateway to fetch it.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call Instagram story and video downloading without a subscription, especially in a web3 or crypto-native workflow using the x402 micropayment protocol. It is suitable for low-volume, on-demand media extraction where paying $0.01 USDC per request is acceptable and a traditional REST API subscription is overkill.

## Known failure modes

- Invalid or private Instagram URL returns upstream 4xx error
- Expired story URL yields empty or error response from upstream
- Payment failure in x402 protocol prevents request from reaching upstream
- Malformed path or query parameters cause upstream API rejection
- Rate limiting from the underlying RapidAPI provider returns 429
- Instagram URL format not recognized by upstream downloader

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream response body from the Instagram downloader API, passed through with its original content-type header after the $0.01 USDC x402 payment is processed. This typically includes the direct download URL or binary media content for the requested Instagram story or video.
