Sample dataFull response

X (Twitter) User Profile API parameters.
3 parameters, 1 required.

Send them as a JSON body with POST. Your key goes in the Authorization header, never in the URL.

NameTypeRequiredDefaultDescription
platformstringRequired—Always "x" on this page.
idstringOne of these—X user ID, a string of digits
usernamestringOne of these—X handle, without the @

Where to get what you send.

id

X user ID, a string of digits (e.g. 11348282)

Every item these return carries its ref; send it as it is:

username

X handle, without the @ (e.g. NASA)

Every item these return carries its username; send it as it is:

X (Twitter) User Profile API response fields.
What X cannot give is marked.

FieldTypeMeaning
items[].usernamestringThe handle.
items[].namestringThe display name.
items[].urlstringA link to the profile.
items[].biostringThe bio.
items[].verifiedbooleanWhether the account is verified.
items[].followersintegerFollower count.
items[].followingintegerHow many accounts it follows.
items[].posts_countintegerHow many posts it has published.
nullFields X cannot give

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

Compared with the Reddit User Profile API, this call also gives followers and following.

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

X (Twitter) User Profile API: paging and billing.

One call returns one object, with no pages, for 1 credit.

5 calls per second per key, 20 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

“Last tested” above is the last day a real call of this interface succeeded. Each call reads from the platform, and fetched_at in the answer is when it was read. The same request sent again with the same key within 5 minutes is a replay (replayed: true): 0 credits, and the answer as first read.

Once connected over MCP, these questions use the X (Twitter) User Profile API.

  1. Look up this X account: 11348282
    user_profile {"platform":"x","id":"11348282"}
    1 credit
  2. Find X accounts about "Smithsonian", then for the first 3: look up this X account.
    search {"platform":"x","query":"Smithsonian","type":"user"}user_profile {"platform":"x","id":"<ref>"} × 3
    8 credits

How to connect
Prompt

Needed: id, username.For several, call it once for each: 1 credit each.Before you start, work out how many credits it will take in all and ask me; call it only after I agree.What usually comes next, with the ref or username it returns: user_posts (User Posts), call x.followers (User followers).If SocialToAI is not connected yet, tell me how to connect it; never ask me to paste a key into the chat.Answer with a link to every item you used, and tell me how many credits it cost.

Paste it into a chat once SocialToAI is connected over MCP. There is no key in it: Claude and ChatGPT sign in, other clients send a key in a header.

X (Twitter) User Profile API: questions.
Short answers.

All X data APIs
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.
What does one call cost in dollars?
1 credit: $0.0033 at 300 credits per dollar (purchases from $10), $0.002 at 500 per dollar (from $200). Credits never expire and there is no subscription. 100 free credits on sign-up, no card.
Am I charged when a call fails or finds nothing?
A failed call costs 0 credits and is never retried on its own.
How much does one call return?
One call returns one object, with no pages, for 1 credit.
Is there a rate limit?
5 calls a second per key, 20 a second after your first purchase. A request over the limit is told how long to wait and is not charged.
How do I use it from Claude, ChatGPT or Cursor?
Yes. In Claude or ChatGPT, add the MCP address https://mcp.socialtoai.com/mcp as a custom connector, sign in with the code we email you and press Allow; there is no key to paste. In Claude Code, run one command, type /mcp, pick socialtoai and sign in; Codex and Cursor sign in too, with their steps on the connect page. Then ask in plain words and your AI calls user_profile for you.
