The open tier runs twelve months behind
This page is what the type field of the error points at. Every answer this API refuses carries one, and it is a stable address rather than a version of the docs.
The refusal
outside-the-open-window- When it happens
- The date asked about falls inside the last twelve months, or knownOn asks what was known after the cut, which is a question about today.
- What to do
- Send a key, or ask about a date the open tier covers: the answer names the most recent open period, or says there is none. Everything older is also published as files, with no key.
The shape of the answer
RFC 9457Problem details: type, title, status and detail, plus whatever the individual failure can usefully add. The detail is written for the person reading the log, and names the parameter or the id that caused it.
| type | This page’s address. Stable. |
|---|---|
| title | The open tier runs twelve months behind |
| status | 402 |
| detail | What went wrong, in this request. |
The full list of failures, with the schema, is in the API documentation.
Where a key comes from
HTTP 402A key is attached to an account rather than handed over once, so losing it is not an incident: sign in and it is there.
