Response
Resource not found (market / order / token).
Structured error response for all API v1 endpoints.
error is the stable machine-readable code and message is human
prose. SDK consumers must branch on error (or the identical
X-Polysim-Code header), never on message. Diagnostic details
and the in-body request_id are added only when callers opt in with
X-Polysim-Verbose: true; X-Request-Id is always present.
Stable machine-readable error code; also returned in X-Polysim-Code.
Human-readable error description. Never branch on this value.
Additional context populated for verbose responses.
Support correlation id; always returned in X-Request-Id.
