Welcome Developers,

Welcome to the Pagefreezer Website Archiving API, where you will find programming instructions, standards, and secure communications for seamlessly integrating your products and services with Pagefreezer’s website archiving capabilities for compliance or legal purposes.

The Pagefreezer API allows developers to send a webpage URL and receive an accurate, SHA-256 digitally signed and full-text searchable PDF of that webpage in return.

pdf example

The Pagefreezer API can add specific value to provide a more extensive compliance or legal coverage by capturing URLs mentioned in social media posts, email messages or digital documents.

api stepsThe PageFreezer API platform has been especially developed for use by our partners. To use the platform, we require authentication through an access token.Register as a partner to get an API access token. You can do this by:
Signing up for a partner account

API Lifecycle

Once you have received your access token you can make API calls to our service.The API lifecycle looks like this:
  1. Send an API request to capture a URL. The API supports either request for a single URL or a bulk request with up to 100,000 URLs at a time. Response: a Task ID (for a single URL) or a Request ID (for a list of URLs)
  2. Check the status of the task/request Response: queued, running, canceled or complete
  3. When complete: download the PDF with task/request ID
  4. Clean up (optional) The PageFreezer API server will keep all PDFs for 30 days if not deleted by request.

APIs

MethodResourceDescription
POST/utils/v1/pdf/convertMake a conversion request
GET/utils/v1/pdf/status/request/:request_idReturn the current status of a conversion request (per request).
DELETE/utils/v1/pdf/status/request/:request_idDelete tasks linked to the request_id.
GET/utils/v1/pdf/status/task/:task_idReturn the current status of a conversion task (per URL).
DELETE/utils/v1/pdf/status/task/:task_idDelete a task linked to the task_id.
GET/utils/v1/pdf/download/task/:task_id.EXTDownload PDF binary file. EXT = pdf or png.
DELETE/utils/v1/pdf/download/task/:task_idDelete rendered PDFs linked to the request_id.
DELETE/utils/v1/pdf/download/request/:request_idDelete a rendered PDF linked to the task_id.
  • Notice
  • Request vs Task
  • For any individual conversion through /utils/v1/pdf/convert, request and task are the same, but for a bulk upload, it gives one request ID as a representative ID for the job and each individual conversion of the bulk job has its own task ID.

 

POST /utils/v1/pdf/convert

Batch Job

  • Prepare a text file (urls.txt) containing multiple URLs. (please make sure the URLs in the file must be validated beforehand.)
$ curl -i -X POST -H “Content-Type: multipart/form-data” \ -F “file_0=@urls.txt” \ -F “url=_file_upload_” \ -F “account_name=demo” \ -F “access_token=0000baa08755a1cd1ad750442e68de7” \ http://pdf.pagefreezer.com/utils/v1/pdf/convert
  • Response (It returned just one request_id because it is a batch job.)
{ “status”: “ok”, “tasks”: [], “access_token”: “0000baa08755a1cd1ad750442e68de7”, “type”: “group”, “request_id”: “23fa6654ec9c6c99fb8d2c5632478f5b_1452641921”, “task_size”: 3 }
  • Get the status on all tasks in the request
curl -X GET -H “Content-Type: application/json” \ -d ‘{“account_name”:”demo”, “access_token”:”0000baa08755a1cd1ad750442e68de7″}’ \ http://pdf.pagefreezer.com/utils/v1/pdf/status/request/23fa6654ec9c6c99fb8d2c5632478f5b_1452641921
