Coverage labels describe operating evidence—not confidence theater.
Retrieval and calculation are operating.
The public sample displays dated BLS observations, source links, a deterministic calculation and explicit limits.
The provider path is being proved.
Credentials or no-key access, request shape and response validation may pass while persistence, monitoring or rights remain open.
The evidence plan exists.
Market structure and candidate sources are mapped, but the source is not presented as current customer coverage.
The complete operating contract has passed.
Rights, runtime retrieval, freshness, durable storage, monitoring, failure recovery and customer-visible claims have recorded evidence.
The source plan spans the signals a market decision actually needs.
MarketKeel's connector work includes primary U.S. government and company evidence for pricing, production, orders, shipments, inventories, trade, employment, regional output, federal spending, agriculture, energy, transportation, patents, filings and operating events. Candidate providers include BLS, Census, BEA, SEC, Treasury Fiscal Data, USAspending, EIA, USDA, USGS, BTS, NHTSA, FCC, CMS, USPTO and SAM.gov.
That list is an engineering and evidence roadmap, not a claim that every provider is production-verified in every market. The public status and individual brief should always take precedence over catalog breadth.
Current means current for the source's own release cycle.
Evidence should show the observation period, publication date, retrieval date and revision state. A monthly government series, a quarterly filing and a continuously updated notice feed have different expectations. When retrieval fails, MarketKeel should retain and label the last known good record rather than substituting an undated value.
Technical access does not create redistribution rights.
Each source is reviewed for permitted retrieval, caching, transformation, model use, display and export. Public-domain status, an API key, a browser page, or a successful response does not automatically approve commercial customer delivery.
Broad market structure is available before broad live evidence.
The catalog helps define markets, submarkets, value chains, decision drivers and research plans. A mapped organization is merely in scope until primary evidence establishes a specific exposure. A market is promoted for paid use only after its commercial readiness record passes.
