CustomDomain (customdomain.ai, styled CustomDomain™) provides custom-domain onboarding for SaaS platforms whose customers bring their own domain: it detects the customer's DNS provider and auto-configures records across 25+ DNS hosts (or shows them), issues SSL automatically, and runs an edge proxy that serves the traffic. It offers a REST API with webhooks, a drop-in connect widget and SDK, and an MCP server so AI agents can connect domains, aimed at site builders, e-commerce platforms, creator tools and agencies.
CustomDomain publishes 25 API contracts indexed on the APIs.io network, including Agents API, Analytics API, Applications API, and 22 more. Tagged areas include Company, Custom Domains, DNS, SSL, and Edge Proxy.
The CustomDomain catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
CustomDomain’s developer surface includes changelog, sandbox, authentication, documentation, API reference, getting-started guide, engineering blog, and 44 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:

Agent readiness — checks not met, largest first (exact, from this profile):
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks Ask about this →
Pagination+5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs Ask about this →
Agentic Commerce Well-Known Document+5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's Ask about this →
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
