Corporate debt
/companies/{id}/debt returns disclosed obligations and their evidence.
/debt/issuers groups bonds by company, largest market cap first by default.
/debt/instruments screens the held instrument registry; a selected instrument
has a detail route. Filter by as-of date, currency, kind and query, and use the
revision-bound cursor when paging instruments. include_matured=true includes
matured instruments with their evidence; the default omits them. A prior disclosure does not establish that
the obligation remains outstanding today.
MCP get_company_debt and screen_corporate_bonds, plus astreus debt, cover
these reads. Source documents use /companies/{id}/debt/sources/{sourceId}.
Native-currency amounts must not be summed across currencies without an explicit
conversion policy. Market yields or valuations require the relevant data rights.
Ownership and management
/ownership, /ownership/transactions, /ownership/insider-history and
/ownership/nationality-history cover different ownership concepts. Keep the
reported share class, date and denominator with a percentage. Transaction
filters can bound dates and owners. /management supplies management and board
information with its associated source events.
Use get_ownership and get_management over MCP. astreus ownership and
astreus management retain their formatted views; the complete operation
interface reaches the history endpoints. Public filings are evidence of a
reported position, not a live beneficial-ownership guarantee.
Supply chains and counterparties
/companies/{id}/supply-chain lists disclosed relationships; /{edgeKey}
retrieves the supporting detail. Keep the relationship role, date, disclosed
amount or concentration, and primary evidence. Absence from held disclosures
does not establish that a supplier/customer relationship does not exist.
Use MCP get_supply_chain or astreus supply-chain. Full parameter schemas
and endpoint-to-tool mappings are in the tool reference.
