## 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-instagram-rapid-endpoint-4f395f5b -d '<json body>'
```

Example prompt: Pull the public profile data for the Instagram account 'natgeo' — I need follower count, bio, and recent post count — and pay the $0.01 USDC fee per the x402 protocol.

## When to prefer this

Choose this endpoint when you need to access Instagram public data programmatically and prefer paying per-call in USDC via the x402 protocol rather than managing OAuth credentials or RapidAPI subscriptions. Ideal for agents with crypto wallets that need lightweight, pay-as-you-go Instagram data access without subscription overhead.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid or unsupported Instagram API path returns upstream 404
- Rate limiting from upstream Instagram/RapidAPI returns 429
- Malformed query parameters result in upstream validation errors
- x402 facilitator unavailable causes payment processing failure
- Private Instagram accounts return empty or restricted data

## How this service works

## Output

The raw upstream Instagram API response body is passed through after successful x402 micropayment verification — typically JSON containing Instagram profile, post, or media data depending on the path queried.
