nullFields X cannot give

X gives every field of this call. Where one item lacks a value, that field is null.

Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format

What to expect.

One call returns the first page only, up to 20 items, with no cursor, for 5 credits.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 5 credits.
On this call X cannot tell a post that does not exist from one with no data: both come back as empty, and both are charged.

1 call per second per key, 5 after a purchase; going over is not charged. Rate limits

A failed call costs 0 credits and is never retried on its own. Error codes

Once connected over MCP, these questions use it.

Questions.
Short answers.

Everything on X
Do I need a X account or X's own API access?
No. You only need a SocialToAI key. The call returns content and account information publicly visible on X; you never sign in to X or apply for anything there.
Can I get the next page?
No. On X this interface gives its first page only (up to 20 items): the response carries no cursor, and page.has_more is always false.
