GET /v1/domains/{domainId}/seo-metrics
Get a domain's SEO authority metrics.
Authentication
Send an API key as a bearer token. This endpoint does not state a specific permission in the specification, so give your key the least it needs and check the response rather than assuming.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X GET https://api.zinndigital.com/v1/domains/{domainId}/seo-metrics \
-H "Authorization: Bearer zdk_live_…"Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
The **cached** authority reading for this domain — Trust Flow, Citation Flow, referring domains and backlinks. Included on every Footprint-Free plan. This never calls the upstream provider, so it is free to render and poll. Use the refresh endpoint to fetch a new reading; each refresh consumes provider allowance. `state` distinguishes three cases that must not be conflated: `measured` (numbers, which may legitimately be zero), `not_in_index` (the provider answered and has never seen this domain), and `never_fetched` (nothing has been requested yet). Individual metrics are nullable — `null` means the provider did not supply that figure, `0` means it measured zero.

state | string<measured, not_in_index, never_fetched> | Yes | `measured` — the provider returned figures (which may be zero, a real measurement). `not_in_index` — the provider answered and has never crawled this domain. `never_fetched` — n… |
measured_at | string | No | When the stored reading was taken. Null when never fetched. |
