Errors

Every refusal has one shape: a code, a message saying what happened and a hint saying what to do.

On this page

Shape

Every error, including sign-in refusals, pages that aren't open yet and every API read, answers in one shape:

{"error": {"code": "…", "message": "…", "hint": "…"}}

The message says what happened and the hint says what to do next. Match on code; the words may change.

Status	Meaning
`400`	The request, an identifier, a query parameter or a cursor is not valid.
`401`	Credentials or a signature are missing or could not be verified.
`403`	The caller may not read this.
`404`	Nothing is there, or it is hidden. Hidden and missing records answer the same.
`409`	The request conflicts with current state, such as a sign-in with no wallet.
`422`	A Credits history cursor or body is not valid.
`429`	Past a request limit; see Limits.
`503`	A service the answer needs could not be reached; try again in a minute.

Each page lists the codes its own requests answer.
