Vercel

Scope and credentials

The adapter adds, retrieves, lists, verifies, and removes domains for one Vercel project. It does not deploy applications, edit customer DNS, register domains, or move a domain from another project. Set VERCEL_TOKEN, VERCEL_PROJECT_ID, and optional VERCEL_TEAM_ID. Give the token only the project/team access required for domain management.

import { createDomainClient } from "@opencoredev/domain-sdk";
import { vercel } from "@opencoredev/domain-sdk/vercel";

export const domains = createDomainClient({
  provider: vercel({
    token: process.env.VERCEL_TOKEN!,
    projectId: process.env.VERCEL_PROJECT_ID!,
    teamId: process.env.VERCEL_TEAM_ID,
  }),
});
const domain = await domains.add("app.customer.com");

DNS, verification, and certificates

Routing records come from Vercel's domain-configuration recommendations; ownership challenges become ownership records. verify() calls the project-domain verification endpoint. The adapter reports active configuration without inventing certificate issuer or expiration metadata unavailable from the project-domain API.

Errors and limitations

Expired tokens map to AUTHENTICATION_FAILED; inaccessible resources map to PERMISSION_DENIED; another project/account maps to DOMAIN_CONFLICT; rate limits preserve retryAfter. Duplicate adds return current state only when projectId matches. Wildcards are not supported in v0.1.
