What the API does for you

Every number has a URL

Statement endpoints return the NSE xbrl_url and filing_date per period. Audit any figure back to the original filing PDF in one click.

ii.

Missing data is visible, not silent

Every ratio series returns null for periods we don't have, plus a coverage: {total, present, missing} block. No guessing what's there.

iii.

Source disagreements surfaced

When primary XBRL and Screener.in differ on a balance sheet, we flag bs_source: both_disagree with per-column diff_pct. You see the conflict, we don't hide it.
