## 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-api-gateway-rapid-instagram-api-90345689 -d '<json body>'
```

Example prompt: Can you fetch the public profile info for the Instagram username 'natgeo' — follower count, bio, and post count — using the QuantaFlow gateway?

## When to prefer this

Use this endpoint when you need pay-per-call access to Instagram public data without a long-term API subscription, and your agent stack already supports the x402 micropayment protocol for USDC-based billing. Ideal for low-volume, on-demand Instagram data lookups where committing to a monthly RapidAPI plan is unnecessary.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not configured for x402 — returns 402 Payment Required
- Invalid path: unrecognized API sub-path forwarded upstream returns 404 or upstream error body
- Rate limit exceeded on upstream Rapid Instagram API — returns 429 Too Many Requests
- Instagram account private or not found — upstream returns empty result or 404
- Malformed query parameters — upstream API returns 400 Bad Request
- Vercel cold start or gateway timeout — intermittent 500 errors on first request

## How this service works

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

## Output

The raw upstream Rapid Instagram API response body is passed through as-is, along with the content type header, after the $0.01 USDC x402 payment is settled. Typical responses include JSON objects with Instagram profile fields, post metadata, engagement metrics, or feed listings depending on the path called.
