Error

Every non-2xx answer.

Every non-2xx answer. The code is stable; message and fix are written so an agent can act on them.

Fields

Field	Type	Description
`error`	string	Machine-readable code, for example ticker_not_tracked. The llms.txt reference lists every code with its HTTP status.
`message`	string	What went wrong, in one sentence.
`fix`	string	What to do next: the route or tool to call, or the input to change. Absent when there is nothing to do.
`docs_url`	url	The developer docs, where keys are created.
`details`	object	Code-specific extras: retry_after_seconds on rate_limited, symbols on invalid_symbol and unknown_symbol, cap and sent on ticker_cap_exceeded, demo_symbols on not_a_demo_symbol. Absent otherwise.
