​
How it works

1

Create a project

A project is a persistent container for processed results and semantic search. Provision one via POST /api/open/v1/projects and wait for its status to become ready (typically 1–2 minutes).
2

Create a job and upload files

Create a processing job inside your project, upload your PDF or document files, then call the complete endpoint to kick off processing.
3

Poll for completion

Poll GET /api/open/v1/jobs/{jobId} until the job status reaches completed or completed_with_errors. Subscribe to a webhook URL on job creation to receive push notifications instead.
4

Retrieve results

Fetch the normalized JSON result from GET /api/open/v1/jobs/{jobId}/result. Query extracted sheets, regions, specifications, and docs through the project entity endpoints, and run semantic search across all processed sources.

​
Key features

Drawings & Specs

Extracts sheets, drawing regions, and specification sections from PDFs — with bounding boxes, labels, and raw text.

Semantic Search

Run natural-language queries across all project sources or search globally across your organization’s projects.

Flexible Uploads

Choose multipart form upload for simplicity or signed direct/multipart uploads for large files and API clients.

Scoped API Keys

Create keys with granular scopes (jobs:read, jobs:write, artifacts:read) and optional expiration dates.
