Canonical company and security
A company is the legal issuer. An instrument is a security traded on an exchange. One company can have multiple securities, symbols or exchange listings, so responses retain both company_id and security_id where applicable.
Resolution behavior
- →Symbols and exchanges are normalized to uppercase.
- →Provider-specific IDs are never accepted as canonical identity.
- →An unresolved reference returns
404; Marked does not silently choose a near match.
