# required_params_not_supported

> HTTP 400 — No provider supports all required parameters.

## HTTP status

`400 invalid_request_error`

## Typical cause

The `require_parameters` constraint lists parameters that no single available provider supports for the requested model.

## Resolution

Relax the required parameters list, or choose a model whose providers support the needed parameters.
