# invalid_keyword

> Invalid keyword. HTTP 400, not retryable.

**HTTP 400: Invalid keyword.** Retrying the same request gives the same error. Errors never cost API credits.

A keyword is 1 to 100 characters after trimming. Send each keyword as its own `q` parameter.

**What to do:** Send keywords of 1-100 characters.

```json Response theme={null}
{
  "type": "https://docs.alura.io/errors/invalid_keyword",
  "title": "Invalid keyword",
  "status": 400,
  "code": "invalid_keyword",
  "detail": "Invalid keyword",
  "suggestion": "Send keywords of 1-100 characters.",
  "retryable": false,
  "request_id": "req_01JQ5W3H8M2N4P6R8T0V2X4Z6B"
}
```

The response is `application/problem+json` (RFC 9457) and has a `Request-Id` header with the same `request_id`. See [all errors](/api-reference/errors).
