Integrate the documented FRED V1 observation shape
Map FRED series observations and metadata while distinguishing V1 fixtures, the newer V2 offering, daily vintages and series-specific usage rights.
Integrate World Bank Indicators V2 without inventing release history
Interpret the response envelope, annual periods, country metadata, null observations and retrieval-based availability in a bounded adapter.
Integrate SEC company facts with accounting context intact
Select entity, taxonomy, concept, unit and period explicitly while preserving filing-date precision and accession ambiguity.
Compare provider interfaces by the evidence they actually expose
Use a technical fit matrix for history, identity, timing, errors and rights instead of ranking APIs by a single speed or field-count score.
