OptionalfetchOptionalrequestClient-wide server timeout in seconds (1–300), sent as X-Request-Timeout to every
operation that accepts it. A per-call requestTimeout overrides it. Omit to use each
operation's server default (trade 5 s, read 10 s, change 15 s, history 30 s,
maintenance 60 s).
OptionalretryOverride individual retry-policy fields.
OptionalscopesOptionaltimeoutMinimum client deadline per request in milliseconds, covering token acquisition,
the request and the response body. Defaults to 30 seconds. For operations with a
server timeout the deadline is extended automatically to that timeout plus 30 s,
so the server's Timeout / OutcomeUnknown / Busy answer is received rather
than cut off by a local abort.
Inject a custom fetch implementation (testing / Bun / Node polyfill).
