Build with FastVision
REST API, six SDKs, and an interactive reference generated straight from the OpenAPI schema. Everything below works identically self-hosted.
Quickstart
Zero to extracted text in three steps
1
Create an account & API key
Register, then mint a key from Dashboard → API keys. Keys look like fv_live_… and are shown once — store them like passwords.
export FASTVISION_API_KEY="fv_live_yourkeyhere"2
Submit your first document
POST a file to /api/v1/ocr/image. The API responds instantly with 202 and a job resource.
curl -X POST https://api-production-5bb4.up.railway.app/api/v1/ocr/image \
-H "X-API-Key: $FASTVISION_API_KEY" \
-F "file=@receipt.png" -F "doc_type=receipt"3
Fetch the result
Poll the job until status is succeeded, or register a webhook and let job.completed come to you.
curl https://api-production-5bb4.up.railway.app/api/v1/jobs/{id}/result \
-H "X-API-Key: $FASTVISION_API_KEY"Guides
