# Criar embeddings

`POST https://ai.inovacc.dev/v1/embeddings`

Transforma um ou mais textos em vetores, no formato de embeddings da OpenAI.

## Parâmetros do corpo

- `input` (string | array), obrigatório: Uma string não vazia ou um array de strings. Volta um vetor por string, na mesma ordem.
- `model` (string): Um id de rota de embeddings de `GET /v1/models`. `auto`, ou nenhum valor, usa a rota padrão da sua organização.
- `encoding_format` (string): Repassado ao modelo quando a rota oferece suporte; ignorado caso contrário.
- `dimensions` (integer): Repassado ao modelo quando a rota oferece suporte; ignorado caso contrário.
- `user` (string): O id do seu usuário final. Antes de sair da Inovacc, é substituído por um valor derivado da sua organização.

## Cabeçalhos

- `Authorization` (string), obrigatório: Bearer <chave de API>
- `X-Operation-Id` (string), obrigatório: um id único que você escolhe, em toda chamada exceto GET
- `Content-Type` (string), obrigatório: application/json, em uma chamada com corpo
