## Paging and failures

- One call returns a page of up to 35 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes.
- A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits.
- 1 call per second per key, 5 after a purchase; going over is not charged. [Rate limits](https://socialtoai.com/docs/credits-and-billing.md#rate-limits)
- A failed call costs 0 credits and is never retried on its own. [Error codes](https://socialtoai.com/docs/api/errors.md)

## FAQ

**Do I need a Instagram account or Instagram's own API access?**

No. You only need a SocialToAI key. The call returns content and account information publicly visible on Instagram; you never sign in to Instagram or apply for anything there.
