How nulls work
Null usually means the issuer did not expose a stable comparable SEC fact for that field and period.
It does not usually mean the API failed.
The API docs focus on the product surface that matters: fundamentals, insider activity, manager holdings, response metadata, auth, and rate limits.
They also explain how to interpret nulls and delayed disclosure datasets without digging through raw SEC forms yourself.
Null usually means the issuer did not expose a stable comparable SEC fact for that field and period.
It does not usually mean the API failed.
Fundamentals return the best available normalized row per period end.
Metrics may use the richest recent row when that produces better TTM and YoY coverage, while 13F reads return the latest reported manager snapshot.
Insider transactions come from SEC ownership forms 3, 4, and 5.
13F holdings are quarterly manager disclosures and should be treated as delayed snapshots rather than real-time positions.
Financial institutions are handled more carefully.
Some ratios are omitted when they are not meaningfully comparable to operating companies.
Responses now include a coverage_class of complete, partial, or sector_limited.
That gives clients a simpler way to interpret sparse rows without custom heuristics.
