USAspending Federal Contract Awards Watch

Monitor new or modified US federal contract awards using the official USAspending.gov API (no API key). Each scheduled run returns awards that are new or changed since the previous run, filtered to your NAICS, PSC, agency, recipient, amount, and state criteria. State is stored in the named key-value store usaspending-awards-watch-state.

Use alongside SAM.gov Contract Opportunities Watch to watch both pre-award solicitations and post-award spending for the same NAICS niche.

Sample run vs. monitoring

Mode	emitAll	What you get
Sample / first look	true	Up to maxResults matching awards (changeType new, updated, or unchanged) so you can inspect the feed.
Scheduled monitoring	false	Only awards that are new or updated since the last successful run. Second run with the same filters typically emits zero rows.

Turn emitAll off after your first run when scheduling daily or hourly checks.

Pricing

Pay per event: $4.00 per 1,000 dataset items returned, plus $0.003 per Actor start (1 GB default memory).
