# Preflight an SSL request

`POST /v1/ssl/preflight`

## Request

- Base URL: `https://developers.servera.co.uk`
- URL: `https://developers.servera.co.uk/v1/ssl/preflight`
- Auth: HTTP bearer

Check, at **zero cost and without touching Let's Encrypt**, how a certificate
would be issued for each domain: which validation method we would auto-pick (hosting
AutoSSL, DNS-01, edge, or a delegated/HTTP-01 fallback), whether wildcards are
supported, and your remaining weekly issuance budget. Only domains you own are
accepted. **Always preflight (or dry-run) before issuing.**

## Request body

- SslPreflightBody
  - `domains` string[], required: Domain(s) to check. Use *.example.com for a wildcard.

## Response `200`
