OptionalallowSend filters without checking their FilterNames and dropdown codes against the
category's columns, and so without the one filterColumns() request per category that
check costs. Default false: a name the category doesn't have, or a code its dropdown
doesn't list, is a MastrValidationError, because the register ignores an unknown name
(the unfiltered set) and answers an unknown code with 0 rows. The shape check and the
name normalisation apply either way.
OptionalbaseBase URL of the API. Defaults to the canonical marktstammdatenregister.de base. A value that breaks a rule of validateBaseUrl (blank, whitespace or control characters, not an absolute http(s) URL, a query or fragment) throws a MastrValidationError.
OptionaldefaultExtra headers sent on every request; names must be tokens, values follow the userAgent rule.
OptionalmaxHard cap on response body size in bytes (defends against memory exhaustion from a hostile/buggy endpoint), a non-negative integer. Defaults to 100 MiB; set to 0 for no limit.
OptionalmaxNumber of automatic retries for transient (429/503) responses and reset
connections (isTransientNetworkError), an integer
0..MAX_RETRIES (10); defaults to 2. Each waits retryDelayMs * attempt, or the
response's Retry-After when that is longer. A Retry-After above
MAX_RETRY_AFTER_MS waits that cap (30 s) and then retries.
OptionalonCalled once per retry, right before the backoff sleep, for each retried status and reset connection; never when there is no retry. A throw is swallowed.
OptionalretryBase backoff between retries in milliseconds (grows linearly: retryDelayMs * attempt),
an integer 0..MAX_RETRY_AFTER_MS (30 000). Defaults to 200. It is also the floor: a
Retry-After can make a wait longer, never shorter.
OptionalsleepInjectable sleep, primarily for deterministic tests.
OptionaltimeoutTime limit per request in milliseconds, covering the whole response body, not
only idle gaps: an integer 0..MAX_TIMEOUT_MS (2^31 - 1 ms); 0 disables.
Defaults to 30000.
OptionaltransportSwappable transport. Defaults to the built-in node http/https transport.
OptionaluserValue of the User-Agent header: not blank, Latin-1 without control characters (tab is fine), else a MastrValidationError.
Options for the MaStR client: the engine options (the API needs no auth) plus one of its own.
