Get one domain
const url = 'https://api.nsin.cloud/reseller/v1/domains/1';const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url https://api.nsin.cloud/reseller/v1/domains/1 \ --header 'Authorization: Bearer <token>'The domain row as stored, handed straight from what tenantGuard already resolved — no second query, and therefore no plan, subscription or traffic data; those are GET /services?client_id= and the analytics endpoints. Remember that suspended, not status, is what decides whether the site is being served.
{domainId} is numeric on this whole surface. The guard parses it as an integer before any handler runs, so GET /reseller/v1/domains/example.com is a 404 rather than a lookup — even though the delegated per-domain routes below are the customer panel’s own handlers, which address a domain by name and would happily resolve one.
A domain that is not in your tenancy answers 404, deliberately indistinguishable from one that does not exist; the 403 is for a caller who is not a reseller at all.

NS-delegation state, driven by the checker — not a billing state.
moved means the nameservers stopped pointing at NSIN.
Billing/administrative stop. This, not status, is what decides
whether the site is served. Set by the negative-balance ladder, or
manually via POST /domains/{domainId}/disable.
WHY the domain is suspended. Empty when suspended is false.
Read this before offering a resume button. Only manual can be
lifted with POST /domains/{domainId}/enable; the other two are
the system’s own and that call returns 409:
manual— you switched it off. Nothing auto-resumes it, which is the point: a client suspended for not paying must not come back online because a quota period rolled over.quota_exceeded— the client used up his plan’s included traffic. A reseller’s client has no pay-as-you-go, so this is his hard stop. Resolve it by moving him to a bigger plan; the quota sweep then resumes the domain by itself.negative_balance— a wallet stayed negative past its grace window. On a client’s domain that is usually yours, not his: the tenancy sweep suspends every domain under a reseller who is in debt, and a client’s own balance has nothing that can drive it below zero. Top your balance back up and billing resumes the domains it suspended.
Example
{ "name": "example.com", "status": "pending", "suspended_reason": "", "dns_mode": "managed"}Authenticated, but the target does not belong to you — or you are not a reseller at all.
This is the response the tenant-isolation matrix asserts on. Every route in this document is called with reseller B’s credential against reseller A’s ids, and must answer 403 or 404 with none of A’s data in the body.
Every error body carries error, a human-readable sentence. Some also
carry code, a stable machine-readable reason — branch on that, never on
the sentence, which is prose and gets reworded.

Present only on the failures worth branching on, and deliberately not an exhaustive enum: treat a code you do not recognise as if it were absent and fall back to the status code.
The ones that exist today:
credit_limit_reached— 402 fromPOST /servicesandPOST /services/{serviceId}/change-plan. Your wallet, not the client’s: funding the purchase would take you past your overdraft (default0, i.e. past zero). Top up; do not credit the client.domain_disabled— 409 from a configuration write on a disabled domain (records, rules, cache, SSL, members, settings). The domain is read-only untilPOST /domains/{domainId}/enable.unknown_rule_type— 404 from the rules paths whenruleTypeis not one of the documented values. You get this rather than an empty array, so a typo cannot read as a rule set that happens to be empty.rate_limited— 429 from any route. Keyed per credential, so one runaway integration cannot lock its owner out of the dashboard.session_check_failed— 503, and only on calls made with a dashboard session JWT. The session could not be verified, which is not the same as knowing it is revoked, so it is retryable and the session survives. Machine tokens never see this.
Example
{ "error": "forbidden", "code": "credit_limit_reached"}No such resource.

Example
{ "error": "forbidden", "code": "credit_limit_reached"}Something failed on our side. The body carries a human sentence and never
an internal detail — a live sweep of this API once returned
dial tcp 127.0.0.1:9000: connect: connection refused, which is our
topology rather than an error message. That is now impossible.
Distinguish it from 503. A 503 means a dependency is down and the
identical request will succeed later, so retry it. A 500 means the request
hit a genuine fault: retrying it unchanged will fail the same way, and it
should be reported with the X-Request-Id from the response header.
Declared on every operation because every operation can reach it. It was previously declared on exactly one, which left a generated client with no branch for the answer it is most likely to be surprised by.
