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

Compared with the WeChat Articles User Profile API, this call also gives bio, verified, followers, following and posts.

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

Bilibili User Profile API: paging and billing.

One call returns one object, with no pages, for 2 credits.

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 Bilibili User Profile API.

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.

Bilibili User Profile API: questions.
Short answers.

All Bilibili data APIs
Do I need a Bilibili account or Bilibili's own API access?
No. You only need a SocialToAI key. The call returns content and account information publicly visible on Bilibili; you never sign in to Bilibili or apply for anything there.
What does one call cost in dollars?
2 credits: $0.0067 at 300 credits per dollar (purchases from $10), $0.004 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 2 credits.
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.
