What it does & execution pool

Start 2-step email registration on a dedicated FullPool device context using your own residential/mobile proxy (Scale+). Executes `/passport/user/check_email_registered, /passport/email/send_code/` on the caller-owned Connected Workspace session (`account_id`), preserving 1:1 hardware identity, cookie state, `X-Cylons` session binding, and city-level egress.

Runs exclusively on a Connected Workspace account_id you own: Executes on the dedicated 1:1 mobile hardware fingerprint, persistent MSSDK sec_device_token, cookie jar, and city egress bound to your own account_id (connected via session import, email OTP login, or Scale+ BYO-proxy email registration). Never an SMM panel: Tikultra never executes likes, follows, comments, DMs, or uploads from shared or internal pool accounts. Passing an unowned or corpus account_id returns 403 account_forbidden.

How to use it (2-Step Scale+ Email Registration with BYO Proxy)

Register a brand-new account on a fresh FullPool hardware profile routed strictly through your own residential or mobile proxy, verify the email OTP, and immediately configure the profile.

Step	Endpoint	Purpose
1	`GET /v1/user/check-username`	Check desired @username availability: Verify your target handle is free with GET /v1/user/check-username (2 credits) before starting registration.
2 ★	`POST /v1/account/register/email/send`	Bootstrap device & send registration code: Pass email, password, birthday (YYYY-MM-DD), region/city, and your residential/mobile proxy URL. Save the returned context_id.
3	`POST /v1/account/register/email/verify`	Verify email OTP & persist account_id: Submit the 6-digit email code along with the exact same context_id and proxy URL to finalize registration and mint account_id.
4	`POST /v1/account/profile/username`	Claim @username & set bio/avatar: Set your handle (/v1/account/profile/username), bio (/v1/account/profile/update), and avatar (/v1/account/profile/avatar).
5	`POST /v1/account/warm/niche`	Calibrate initial For You niche: Warm the newly registered session with organic topic searches and feed dwells via POST /v1/account/warm/niche.

What it returns

Returns `200 OK` `application/json` decoded from `/passport/user/check_email_registered`. Field names (`aweme_id`, `uid`, `sec_uid`, `unique_id`, `room_id`, `product_id`) are consistent across all 200+ endpoints so outputs pipe directly into follow-up calls. If TikTok returns an upstream timeout, empty challenge, or 5xx error, the gateway surfaces a structured error `code` and sets `x-credits-cost: 0`. Every response carries x-credits-cost, x-credits-tier and x-credits-remaining. Error codes
