How this service works
FastAPI Declared dependencies: Live PyPI declared dependencies for FastAPI. Package name can be overridden.
Output

Example use cases
Auditing FastAPI dependency chain
“Can you pull the live declared dependencies for the fastapi package from PyPI so I can review what it requires?”
Checking dependencies for a custom Python package
“Look up the declared PyPI dependencies for the 'starlette' package — I want to see exactly what it officially declares as its requirements.”
Comparing dependency lists across releases
“Fetch the current declared dependencies for the 'pydantic' package on PyPI so I can compare them against the ones we have pinned in our project.”

Endpoint
POSThttps://market.datapackvibe.com/x402/demand-next-package-pypi-fastapi-dependency-list?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, up-to-date declared dependency information for a specific PyPI package (especially FastAPI by default) and want to avoid scraping PyPI yourself. Prefer it over static documentation or local package inspections when you need the canonical, currently published dependency list from PyPI.
Side effects
- Package not found on PyPI — returns an error or empty response
- PyPI API unavailable or rate-limited — request may time out
- Malformed or missing dependency metadata in the package's PyPI record
- Invalid package name input causes lookup failure
