Milo FedSpend API

One normalised JSON wrapper over USAspending.gov contract awards and the Federal Register of proposed and final rules. Built on US federal open data — free to integrate, billed per call via RapidAPI.

Why this API

The raw USAspending.gov REST surface is real and public — but it is a multi-step POST API with awkward payloads and inconsistent field names, and it ships nowhere on RapidAPI. The Federal Register public API exists but exposes raw schema with no normalisation. This wrapper gives you both behind one auth, one JSON shape, one bill.
