Obter chave de API

Documentação / Primeiros passos

Início rápido

Obtenha uma chave de API, busque um medicamento e leia o resultado. Leva cerca de cinco minutos.

1. Obtenha uma chave de API

Crie uma chave na página de cadastro. Ela começa com mf_live_ e funciona imediatamente para todos os países. Obtenha sua chave de API.

Armazene-a em uma variável de ambiente no seu servidor:

export MEDIFONTIS_API_KEY="mf_live_…"

Chame GET /v1/drugs com um código de país e um termo de busca:

GET /v1/drugs 
curl -G https://api.medifontis.com/v1/drugs \
  -H "Authorization: Bearer $MEDIFONTIS_API_KEY" \
  --data-urlencode "country=br" \
  --data-urlencode "q=dipirona sodica"

3. Leia a resposta

Cada resultado é um registro de uma fonte. Os campos que você mais vai usar são name, identifiers, sourceId e kind, data e licence.

4. Percorra as páginas de resultados

nextOffset é o offset da próxima página, ou null na última. Passe-o como offset para ler a próxima página:

Node.js 
async function* searchAll(country, q) {
  let offset = 0
  while (offset !== null) {
    const params = new URLSearchParams({ country, q, limit: '50', offset: String(offset) })
    const response = await fetch(`https://api.medifontis.com/v1/drugs?${params}`, {
      headers: { Authorization: `Bearer ${process.env.MEDIFONTIS_API_KEY}` },
    })
    if (!response.ok) throw new Error(`Medifontis ${response.status}`)
    const page = await response.json()
    yield* page.results
    offset = page.nextOffset
  }
}
