Quickstart ​

Three steps to a birth certificate's data as JSON.

1. Create an API key ​

In the panel, under API Keys, create a key for your workspace. Keep it like a password: it goes in the Authorization header of every request. See Authentication.

2. Make your first call ​

This code sends the sample certificate we host, with fictitious data. Put your key in the DOCSOCR_API_KEY environment variable and run:

bash
#!/usr/bin/env bash
# Your first call: extract the hosted sample certificate (fictitious data).
# Needs DOCSOCR_API_KEY in the environment; create a key in the panel.
set -euo pipefail

REQUEST_ID="first-call-$(date +%s)-$RANDOM" # one id per document

# The API answers within 90 s
curl -sS --max-time 120 https://api.docsocr.com/api/v1/documents/birth-certificate \
  -H "Authorization: Bearer $DOCSOCR_API_KEY" \
  -H "Content-Type: application/json" \
  --data-binary @- <<EOF
{
  "imageType": "url",
  "imageUrl": "https://docsocr.com/samples/certidao-nascimento-exemplo.jpg",
  "requestId": "$REQUEST_ID"
}

Rather not write code? Use the reference's Try it or the Postman collection.

3. Read the answer ​

The extraction answers with status 201 and a JSON body:

  • success: true when the answer carries the certificate's data;
  • data: the certificate's fields, with Portuguese, accented keys such as dados_pessoais.nome_completo and filiação.genitor_1.nome_completo. They are all in Response fields;
  • engine: the engine that answered;
  • creditsCharged: what the request cost.

With success: false, no engine could answer: the errorCode says why, and nothing was charged. An image that cannot be used is refused with 422, also at no charge. The codes are in Errors.
