# `Nous.Errors.ProviderError`
[🔗](https://github.com/nyo16/nous/blob/v0.17.1/lib/nous/errors.ex#L56)

Error from an LLM provider.

Raised when a provider API call fails.

## Fields

  * `:provider` — provider id atom (e.g., `:vertex_ai`)
  * `:status_code` — HTTP status when applicable
  * `:retry_after_ms` — server-suggested backoff in milliseconds, parsed
    from the response body (`google.rpc.RetryInfo`) or `Retry-After`
    header. `nil` when the failure is not retry-hinted (e.g. daily quota
    exhaustion deliberately omits `RetryInfo` per Google's spec).
  * `:details` — raw error payload from the HTTP layer

# `t`

```elixir
@type t() :: %Nous.Errors.ProviderError{
  __exception__: true,
  details: any(),
  message: String.t(),
  provider: atom() | nil,
  retry_after_ms: pos_integer() | nil,
  status_code: integer() | nil
}
```
