Proxies paid HTTP requests to a Rapid Instagram API upstream endpoint via the x402 micropayment protocol, charging $0.01 USDC per call.

## 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-a6a33178 -d '<json body>'
```

Example prompt: Can you pull the public profile info and recent posts for the Instagram account @natgeo using the QuantaFlow paid gateway — I'm okay spending the $0.01 USDC per call.

## When to prefer this

Choose this endpoint when you need metered, pay-per-call access to Instagram public data without a long-term API subscription, especially in web3/agent contexts where x402 micropayments via USDC are the preferred payment mechanism. It is particularly useful for AI agents with onchain wallets that can autonomously authorize $0.01 USDC payments per lookup without human billing setup.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not connected returns 402 Payment Required
- Invalid path: incorrect upstream path returns upstream 404 or error JSON
- Rate limiting: upstream Instagram API quota exceeded returns 429 Too Many Requests
- Private account: attempting to fetch data for a private Instagram account returns empty or restricted response
- Malformed query: invalid query parameter format causes upstream 400 Bad Request
- Gateway downtime: Vercel or upstream service unavailable returns 503

## How this service works

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

## Output

The raw upstream Instagram API response body (JSON) is passed through directly after the x402 micropayment is processed, along with the content type header. The response contains whatever the selected Instagram API endpoint returns — profile data, post lists, media metadata, etc.
