Douyin Short UID to Sec User ID Lookup

omnial/douyin-web-encrypt-uid-to-sec-user-id

Given a Douyin account's short numeric uid, returns that account's sec_user_id -- the opaque, long-form id Douyin's profile, video, and live-stream endpoints accept as a lookup key. A sec_user_id is derived for any well-formed numeric uid, even one no account is known behind; a non-numeric uid returns an empty shell at no charge.

Pricing

Every real charge, itemised. A model that quietly omits one is a slow financial leak, so nothing here is rolled up, and a charge that only applies to some inputs says so rather than being added in.

Prices in this catalog are the provider's own list price, not your bill: Omnial MCP charges provider cost plus a platform markup on top, so what you are charged is higher than the figure shown. For the exact amount a specific call will cost, run omnial_execute with dry_run: true; that number includes the markup and is what we hold while the call runs. It is a quote, not a cap on the charge.

Charge	Rate
Per call Flat, regardless of what comes back	$0.0020475

Cost basis: Not recorded
This tool's catalog entry does not record how its final bill is determined, so we will not tell you whether its cost is fixed before the call or reported by the provider afterwards. Either way what is held is a quote rather than a cap: you are charged what the call actually costs, bounded at 2x the quote.
