Financial Knowledge Graph API
Graph returns the connected view of a name: its sector, ETFs, peers, suppliers, leadership, and macro exposures, plus the related tickers worth checking alongside it.
What it returns
The response returns known, a relationships map keyed by relation type, a flattened connected node list (type, human relation, entity), related_symbols (peers plus names sharing an ETF or sector), a narrative, a trust block, and a source/storage indicator of seed versus live+seed.
Relation types include in_sector, in_industry, held_by_etf, peer_of, supplied_by, led_by, exposed_to, recent_filing, and traded_by_congress.
When to use it
Use Graph to answer 'what else should I be looking at?' for a name: its cohort, supply chain, and macro drivers. It is the primitive other engines lean on, and related_symbols is the direct 'cross-check these tickers' answer.
On each call it best-effort hydrates live edges (Polygon peers and sector, SEC EDGAR industry and recent filings, congressional trades via FMP) when keys or flags are set; offline it uses the seed graph unchanged.
Notes and honesty
Offline this is a curated seed of well-known relationships plus derived edges, clearly labeled as seed in source. Live sources merge over the seed via the same register_edges contract when configured. The graph describes relationships in the data, never a buy or sell view, and records nothing.
- relationships: sector, ETFs, peers, suppliers, leadership, macro
- connected: flattened node list with human-readable relations
- related_symbols: tickers worth cross-checking
- narrative: plain-language summary of the neighborhood
- source/storage: seed or live+seed
- trust envelope (deterministic, ungrounded when no edges)

Questions
Is the graph data live?
Offline it is a curated seed of well-known relationships, labeled as seed. When Polygon, SEC EDGAR, or FMP are configured, live peers, sector, filings, and congressional trades merge over the seed and source reads live+seed.
What is related_symbols?
The tickers worth checking alongside this one: its peers plus names that share an ETF or a sector. It is the 'what else should I look at?' answer other engines reuse.
Does the graph give trading views?
No. It describes structural relationships in the data only, never a buy or sell view, and it records nothing.
