Data Sources & Cadence
Every record on GovBizOpps traces back to a public federal source. We don't synthesize. We don't speculate. We normalize agency codes, link related solicitations across modifications, and resolve recipient parent–subsidiary relationships using the SAM.gov UEI graph.
SAM.gov Opportunities API v2
Endpoint: https://api.sam.gov/prod/opportunities/v2/search
Cadence: 1 call per day at 5am ET. We pull modifiedSince=yesterday to capture all new and updated VA IT opportunities. Public/basic SAM.gov API keys are limited to 10 calls per day; our pipeline budgets 1 call for the daily sync and reserves the other 9 for audit lookups and backfills.
Filters applied at ingest: Agency 036 (Department of Veterans Affairs). NAICS 541511, 541512, 541519, 518210. PSC D-series (IT services) and 70-series (information technology equipment).
USAspending.gov API
Endpoint: https://api.usaspending.gov/
Cadence: nightly full sync. No authentication required. Covers federal awards back to FY09. We filter by Agency 036 and the same NAICS set above.
FPDS-NG ATOM Feed
Endpoint: https://www.fpds.gov/ezsearch/
Cadence: daily reconciliation. No authentication. Contract action level detail — we use it to resolve modifications, set-aside categories, and discrepancies that USAspending sometimes carries.
SAM.gov Entity API + GSA eLibrary
Used for enrichment: UEI to parent-company resolution, schedule-holder lookups, and socio-economic certification records.
What we don't store
- Personal information beyond what's in public federal records (e.g., a Contracting Officer's published name is on file; their personal contact is not).
- Document contents. We index SOW PDFs by metadata only; the documents themselves stay on SAM.gov.
- Any data more than 17 years old (the limit of USAspending coverage).
