Provider

When multiple model providers are available, optionally indicate your routing preference.

Fields

Field	Type	Required	Description	Example
allow_fallbacks	OptionalNullable[bool]	➖	Whether to allow backup providers to serve requests - true: (default) when the primary provider (or your custom providers in "order") is unavailable, use the next best provider. - false: use only the primary/custom provider, and return the upstream error if it's unavailable.
require_parameters	OptionalNullable[bool]	➖	Whether to filter providers to only those that support the parameters you've provided. If this setting is omitted or set to false, then providers will receive only the parameters they support, and ignore the rest.
data_collection	OptionalNullable[models.DataCollection]	➖	Data collection setting. If no available model provider meets the requirement, your request will return an error. - allow: (default) allow providers which store user data non-transiently and may train on it - deny: use only providers which do not collect user data.	deny
zdr	OptionalNullable[bool]	➖	Whether to restrict routing to only ZDR (Zero Data Retention) endpoints. When true, only endpoints that do not retain prompts will be used.	true
enforce_distillable_text	OptionalNullable[bool]	➖	Whether to restrict routing to only models that allow text distillation. When true, only models where the author has allowed distillation will be used.	true
order	List[models.Order]	➖	An ordered list of provider slugs. The router will attempt to use the first provider in the subset of this list that supports your requested model, and fall back to the next if it is unavailable. If no providers are available, the request will fail with an error message.
only	List[models.Only]	➖	List of provider slugs to allow. If provided, this list is merged with your account-wide allowed provider settings for this request.
ignore	List[models.Ignore]	➖	List of provider slugs to ignore. If provided, this list is merged with your account-wide ignored provider settings for this request.
quantizations	List[models.Quantization]	➖	A list of quantization levels to filter the provider by.
sort	OptionalNullable[models.Sort]	➖	The sorting strategy to use for this request, if "order" is not specified. When set, no load balancing is performed.	price
max_price	Optional[models.MaxPrice]	➖	The object specifying the maximum price you want to pay for this request. USD price per million tokens, for prompt and completion.
