OpenAPI Specification

openapi: 3.2.0
info:
  title: Domainee Service API
  version: 1.0.0
  summary: Custom domains, domain registration, and DNS diagnostics for SaaS products.
  description: 'Domainee lets your product attach your customers'' own domains to their accounts:

    one call to connect a hostname, automatic SSL issuance and renewal, DNS health

    monitoring, webhooks, and domain registration across 500+ TLDs.


    ## Authentication


    Every `/v1` endpoint except `/v1/tools/*` takes a Bearer token in the

    `Authorization` header. Two kinds work interchangeably:


    - **API keys** (`sk_live_…`), created at https://domainee.dev/developers

    - **OAuth access tokens** (`dmn_oat_…`), issued by the flow described in

    the `/.well-known/oauth-authorization-server` document.


    Both are workspace-scoped: a token only ever sees its own workspace''s data.


    ## Rate limits


    Authenticated endpoints allow 60 requests per minute per key and answer `429`

    with `{"error":"rate_limited"}` beyond that. The free tools are limited per IP

    at 30/minute and 500/day.


    ## Idempotency


    Send an `Idempotency-Key` header on any POST to make a retry safe: the first

    response for a given key is replayed instead of performing the work twice.


    ## Errors


    Failures return the same envelope at every status code:

    `{ "error": "not_found", "message": "Domain not found" }`.
