Supported Inputs

PDF bytes

from awb_extractor import AWBExtractor

extractor = AWBExtractor(api_key="sk-ant-...")

with open("label.pdf", "rb") as file:
    result = extractor.from_bytes(file.read())

Local PDF file

from awb_extractor import AWBExtractor

extractor = AWBExtractor(api_key="sk-ant-...")
result = extractor.from_file("label.pdf")

PDF URL

from awb_extractor import AWBExtractor

extractor = AWBExtractor(
    api_key="sk-ant-...",
    http_headers={"Authorization": "Bearer token"},
)

result = extractor.from_url("https://example.com/awb.pdf")

You can pass request-specific headers with extra_headers:

result = extractor.from_url(
    "https://example.com/awb.pdf",
    extra_headers={"X-Request-ID": "request-123"},
)

Multiple URLs

from_urls() returns a list of dictionaries with url, data, and error. Failed URLs do not stop the whole batch.

from awb_extractor import AWBExtractor

extractor = AWBExtractor(api_key="sk-ant-...")
results = extractor.from_urls([
    "https://example.com/good.pdf",
    "https://example.com/bad.pdf",
])

Publishing

GitHub Actions builds and publishes the package to PyPI on every push to main.

The repository must define this GitHub secret:

PYPI_API_TOKEN

PyPI does not allow replacing an existing version. If a commit on main does not bump project.version in pyproject.toml, the publish step skips the existing distribution.
