# Pre-check a carrier registration

`POST /v1/messaging/sms/registrations/preflight`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/messaging/sms/registrations/preflight`
- Auth: HTTP bearer

Dry-run of `POST /v1/sms/registrations` for 10DLC: validates and
composes the exact brand/campaign payloads a submission would store
(branding, disclosures, auto-replies), runs deterministic compliance
lints plus an AI reviewer over them, and returns the findings WITHOUT
creating anything. Use it to fix issues before submitting; `block`
severity findings indicate a near-certain carrier rejection.


**Billing:** Request; paid actions are priced in credits (see GET /v1/messaging/prices) · **Rate limit:** 60/min

## Headers

Completed

- object

  - `tag` string, nullable: Your X-Tag, if sent
  - `created_at` string, date-time
  - `completed_at` string, date-time, nullable
  - `output` object: Operation result (see each operation). While a Studio render is processing: `stage` (queued · transcribing · downloading · preparing · cleaning_voice · mixing_audio · rendering · finishing), `phase` (the engine's: download · prepare · voice · audio · encode · qa · upload, or null), `progress` (a percent, 0–100) and `progress_fraction` (0–1), `eta_seconds` (seconds left, never below 0) and `estimate_seconds`
    - `verdict` 'pass' | 'warn' | 'fail' | 'unreviewed'
