Check what my credential actually reaches

GET

/reseller/v1/diagnostics

const url = 'https://api.nsin.cloud/reseller/v1/diagnostics';
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/diagnostics \
  --header 'Authorization: Bearer <token>'

One authenticated round trip that reports what arrived: which credential, which reseller it resolved to, and what budget it is spending.

Point a new integration here first. Reaching it at all proves four separate things that are otherwise diagnosed one painful step at a time — that the base URL is right, that TLS completed, that the credential parsed, and that it maps to the tenancy you expected.

base_url is the origin this API is served from. If the host you called is not the one it names, that difference is the bug: the marketing site answers /api/... with a redirect and then an HTML 404, which reaches a JSON client as a parse error rather than as anything about the URL.

Missing, malformed, expired, or revoked credential.

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.

code

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 from POST /services and POST /services/{serviceId}/change-plan. Your wallet, not the client’s: funding the purchase would take you past your overdraft (default 0, 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 until POST /domains/{domainId}/enable.
unknown_rule_type — 404 from the rules paths when ruleType is 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"

403

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.

500

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.
