Stock market data infrastructure
Company profiles and fundamentals API
Retrieve listing identity, descriptive company fields, completeness signals, and calculated metrics without assuming every field is populated.
Documentation revised
Identity before enrichment
The company detail response includes ticker, exchange, name, classification, and available business profile fields. Description, website, employees, and headquarters are nullable enrichment fields. Preserve listing identity as the join key rather than matching only a company name.
Separate profile and metric inputs
Market snapshots and reporting statements update on different schedules. The metrics summary route calculates ratios from available inputs; null can reflect a missing input or a metric that cannot be calculated meaningfully. Formula definitions are available through /api/v1/formulas.
Inspect quality signals
Use data_completeness, has_price_data, and latest_financials_date as starting signals. A completeness score describes populated fields; it is not an audit opinion or a guarantee of accuracy. Refresh temporary profile_markdown_url values from the profile response when needed.
