Installation

# Step 1 — create venv
python -m venv venv
.\venv\Scripts\activate   # Windows
# source venv/bin/activate  # Linux/Mac

# Step 2 — install litellm (pinned)
pip install "litellm==1.59.12" --no-cache-dir

# Step 3 — install mapper (from sibling modules3/mapper/)
pip install -e ../mapper --no-cache-dir --no-deps
pip install PyMuPDF tiktoken pydantic pydantic-settings python-dotenv tenacity requests aiohttp httpx numpy tqdm python-json-logger --no-cache-dir

# Step 4 — install extractor
pip install -e . --no-cache-dir --no-deps
pip install python-docx python-pptx openpyxl --no-cache-dir

# Verify
python -c "import pdf_autofillr_doc_upload; print('extractor ok')"
python -c "import pdf_autofillr_mapper; print('mapper ok')"

Setup

1. Copy sample configs

python -c "import pdf_autofillr_doc_upload; pdf_autofillr_doc_upload.copy_sample_configs('.')"

2. Create .env

cp .env.example .env
# Edit .env — set DOC_UPLOAD_LLM_MODEL and DOC_UPLOAD_LLM_API_KEY at minimum

Minimal .env:

DOC_UPLOAD_LLM_MODEL=openai/gpt-4.1-mini
DOC_UPLOAD_LLM_API_KEY=sk-...
DOC_UPLOAD_STORAGE=local
DOC_UPLOAD_DATA_PATH=./extractor_data
DOC_UPLOAD_CONFIG_PATH=./configs

---

Running

Interactive local runner

python -m entrypoints.local

Non-interactive (single document)

python -m entrypoints.local --document investor.pdf --schema configs/form_keys.json --output output/filled.json

CLI

doc-upload-cli --document investor.pdf --schema configs/form_keys.json --output filled.json --report

FastAPI server

doc-upload-server
# or
uvicorn entrypoints.fastapi_app:app --reload --port 8001

Then POST to http://localhost:8001/extract:

{
  "document_path": "/path/to/investor_profile.pdf",
  "schema_path": "configs/form_keys.json"
}

---

Storage backends

Value	Description
local	Local filesystem (default, for dev)
s3	AWS S3
gcp	Google Cloud Storage
azure	Azure Blob Storage

Set DOC_UPLOAD_STORAGE=s3 and the matching bucket env vars.

---

PDF Filling (mapper integration)

Set DOC_UPLOAD_PDF_FILLER=mapper and the Lambda URL:

DOC_UPLOAD_PDF_FILLER=mapper
DOC_UPLOAD_FILL_PDF_LAMBDA_URL=https://xyz.lambda-url.us-east-1.on.aws
DOC_UPLOAD_PDF_API_KEY=my-api-key

The client runs extraction and embed-file preparation in parallel, then calls fill_pdf once both complete — identical to the Lambda main.py pipeline.

---

Telemetry

Value	Description
off	Disabled (default, zero overhead)
local	Append events to ./extractor_telemetry/events.jsonl
managed	(stub) HTTP POST to DOC_UPLOAD_TELEMETRY_ENDPOINT

Field values are never included in telemetry. Only metadata (counts, latencies, file extensions) is logged. Job IDs are one-way SHA-256 hashed.

---

Entrypoints

File	Use case
entrypoints/local.py	Interactive development REPL
entrypoints/cli.py	doc-upload-cli command
entrypoints/server.py	doc-upload-server (uvicorn)
entrypoints/fastapi_app.py	FastAPI app (mount or standalone)
entrypoints/aws_lambda.py	AWS Lambda handler
entrypoints/gcp_function.py	GCP Cloud Functions handler
entrypoints/azure_function.py	Azure Functions handler

---

Programmatic API

from pdf_autofillr_doc_upload import DocUploadClient

client = DocUploadClient()

# Extract only
result = client.run(
    document_path="investor_profile.pdf",
    schema_path="configs/form_keys.json",
    output_path="output/filled.json",
)

print(result["output_flat"])   # flat dot-notation dict
print(result["output_nested"]) # nested dict matching schema

# Extract + fill PDF
result = client.run(
    document_path="investor_profile.pdf",
    schema_path="configs/form_keys.json",
    user_id="42",
    pdf_doc_id="99",
    session_id="sess_abc",
    investor_type="Individual",
)
