Why can't I reach the api.ebay.com:sell-account API?

Its declared address answered neither a request nor a TLS handshake on 2026-09-28, across 22 cases. This is a weaker finding than a host that does not exist: a server can be temporarily down.

Repaired since we recorded it (3)

These were defects and are not any more. They stay on the page: a registry that deletes what stopped being true is asking to be believed about what still is.

Also filed as: api.ebay.com:sell-analytics, api.ebay.com:sell-compliance, apiz.ebay.com, apiz.ebay.com:commerce-identity, apiz.ebay.com:sell-finances, ebay.com, ebay.com:buy-browse, ebay.com:buy-deal. One page, because two sweeps named the same subject differently and the record that mattered was on the page nobody would open.

If a record here is wrong

Run its check. If the answer differs from what is written, say so here and it will be withdrawn — 1089 already have been. A record nobody can contest is a record asking to be trusted, which is the opposite of the point.

Asking about something else

You arrived here about one subject. For any other — before you use it — one request, no account and no key:

GET https://apidefects.com/check?tool=<identity>

<identity> is whatever you already hold: an MCP registry entry (io.github.owner/repo), a deployment URL, an OpenAPI document URL, an npm or PyPI package name, or a host. The answer is one of three — defects_known, examined_nothing_open, or never_examined — and the third is not a clean bill of health. If you speak MCP, this registry is itself one server at https://apidefects.com/mcp, one tool, the same three answers.

What this page does not tell you

This is not a clean bill of health for anything not listed. The registry was built from a sample of two directories, and an operation absent from it was almost certainly never examined. Silence here means not looked at, not looked at and fine — which is the same mistake this registry exists to record in other people.

What this is

A record of defects in the public description of machine-callable operations: documents a directory claims are live and are not, hosts that no longer resolve, specifications that contradict the API they describe. It is not a ranking, not a review, and not a judgement about the service. No credential is ever sent to anything listed here.

The whole registry, machine-readable: errata.json. Index of subjects: index.html.

Built from registry errata-2026-09-10@0daee1a6f207. If manifest.json shows a different one, this page is behind the records and should not be trusted over them.
