### `buscar_promocoes`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Lista produtos em promoção no Mercado Livre Brasil, com preço atual, preço de tabela, percentual de desconto e o cupom aplicável quando existe. Use para responder perguntas como 'o que está barato em eletrônicos' ou 'promoções acima de 50% de desconto'.
```

### `melhor_cupom`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Dado um link ou MLB id de produto do Mercado Livre, devolve o cupom com maior chance de funcionar, o quanto economiza e se o desconto é verificável ou condicional. Cupom 'conditional' depende de restrição que não dá para verificar de fora (itens selecionados, marca, assinatura) e NÃO deve ser apresentado como desconto garantido.
```

### `quedas_de_preco`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Lista produtos cujo preço caiu de forma relevante nas últimas horas, incluindo os que atingiram o menor preço já registrado desde que passaram a ser monitorados.
```
