## 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-endpoint-f249b4fa -d '<json body>'
```

Example prompt: Look up the Instagram profile info and recent posts for the account 'natgeo' — I need follower count, bio, and the latest 10 post captions.

## When to prefer this

Choose this endpoint when you need Instagram social data (profiles, posts, metrics, hashtags) and want to pay per-call via x402 USDC micropayments without managing a separate RapidAPI subscription or API key. Ideal for AI agents with a crypto wallet that need occasional Instagram lookups without committing to a monthly API plan. Not suitable for high-volume scraping or when you need guaranteed SLA.

## Known failure modes

- Payment failure: insufficient USDC balance or invalid x402 payment header returns 402 Payment Required
- Invalid path: unrecognized API path below upstream origin returns 404 or upstream error
- Malformed query/body: upstream API rejects bad parameters, returns upstream error code
- Rate limiting: upstream Instagram data provider throttles requests, returns 429
- Instagram data unavailable: private accounts or deleted content return empty or error responses
- Network timeout: upstream service unreachable returns 504 or connection error
