Fund Data API
Positions, NAV, risk, and fees — read-only
Twelve GET endpoints, one per real analyst tool. Every response is redacted at the edge, fail-closed — the same posture as Nyx Analyst.
Fund Overview
The fund's base currency, inception date, AUM target, share classes, and latest NAV summary.
Requires an Authorization: Bearer <API key> header (a nyx_dk_… developer key, minted from Settings → Developer). Reflects Nyx's shadow NAV, reconciled against your fund administrator.
No parameters — call it with no query string.
