```

**One API, any CAS format.** Send a PDF, get structured JSON. Works with all Indian depositories and registrars — CDSL, NSDL, CAMS, KFintech.

<Note>
  **Cross-depository coverage:** CDSL and NSDL eCAS statements contain holdings from **both** depositories, not just the issuing one. This consolidated view includes all demat and non-demat assets across CDSL and NSDL accounts.
