# provider_not_in_allowlist

> HTTP 400 — No provider in the allowlist supports this model.

## HTTP status

`400 invalid_request_error`

## Typical cause

The `providers` allowlist parameter restricts routing to providers that do not serve the requested model.

## Resolution

Add a provider that supports the model to the allowlist, or remove the allowlist constraint.
