China social media data API: one key for Xiaohongshu, Douyin, WeChat (2026)

Why one key?

Joining each platform apart means separate sign-ups, top-ups, field names and errors, and a new parser for every platform. With one key and one shape, a new platform is one word in the path: the author is always in author, counts in metrics, and the next page always comes from page.next_cursor.

What to check

Where DataXAPI stands on each, to set against any other service.

One job on three platforms

Look up 防晒霜 (sunscreen): a page of Xiaohongshu search $0.0200, Douyin $0.0200 and WeChat Search $0.0200, 3 calls, $0.06, each returning the same kind of post object, ready to go into one table.

Why DataXAPI

• Steady: endpoints were available 99.9% of the last 30 days, on a public status page you can check.
• Fast: a paid call took 2.5 seconds at the median over the last 7 days (counted 2026-11-06).
• Fewer tokens: across 226 endpoints, one recorded real response each, the platform's own JSON comes to 9.2M tokens and what an AI reads through DataXAPI's MCP server to 452k, 95% fewer; the JSON of a direct API call is 90% fewer too (counted 2026-11-06). Every platform answers in one shape: the author in author, counts in metrics, the next page in page.next_cursor, so another platform needs no new parser.
• See before you pay: every endpoint's page shows a recorded real response, field by field.
• Spending you control: a failed call is not charged; each key can have a limit, X-Max-Price caps one call, and the same Idempotency-Key within 24 hours is never charged twice.
• Ready for AI: a remote MCP server listed in the official MCP registry as com.dataxapi/mcp, usable from Claude, Cursor and ChatGPT.
• Free trial of up to 333 calls, no card.

Endpoints

Each with its price; every page has the parameters, the fields and a recorded response.
