Routing

Provider Routing

Select and filter serving providers.

The provider object uses OpenRouter field names and semantics.

Field	Type	Effect
`order`	string[]	Try these providers first in order, then other eligible providers.
`only`	string[]	Allow only these providers.
`ignore`	string[]	Exclude these providers.
`sort`	string or object with `by`	Sort by `price`, `throughput`, or `latency`.
`allow_fallbacks`	boolean	With `false`, use only the ordered providers or the first host.
`data_collection`	string	`deny` keeps hosts marked as denying collection.
`zdr`	boolean	`true` keeps zero data retention hosts.
`quantizations`	string[]	Keep listed quantizations; `unknown` matches an unset value.
`max_price`	object	Maximum `prompt` and `completion` prices in USD per 1M tokens.
Default config order pins the first host for each model, plaingateway only.
A filter that leaves no host returns 404 with routing details.
