The ARN (and its EUIN) is screened against AMFI's suspended, terminated, and terminated-EUIN lists; a hit sets `registration_status` to `SUSPENDED`/`TERMINATED`, `negative_list_hit` to `true`, and `verified` to `false`. **Credits:** 0.25 per successful verification. ## OpenAPI ````yaml /api-reference/openapi.yaml post /v1/verify/mfd openapi: 3.1.0 info: title: CAS Parser - Track Portfolios from CDSL, NSDL, CAMS, KFintech description: >- API for parsing and analyzing CAS (Consolidated Account Statement) PDF files from NSDL, CDSL, and CAMS/KFintech, with a unified response format version: 4.0.0 contact: name: Sameer Kumar email: sameer@casparser.in servers: - url: https://api.casparser.in description: Production server - url: https://portfolio-parser.api.casparser.in description: Legacy production server (still supported) - url: http://localhost:5000 description: Local development server security: [] tags: - name: CAS Parser description: Endpoints for parsing CAS PDF files from different sources. - name: CAS Generator description: >- Endpoints for generating new CAS documents via email mailback (KFintech and CAMS). - name: CAS Fetch description: | Endpoints for fetching CAS documents with instant download. Currently supports CDSL via OTP authentication. - name: Email Import description: > Endpoints for importing CAS files directly from user email inboxes. **Supported Providers:** - **Gmail** (`gmail`, default) — `@gmail.com` and Google Workspace domains - **Microsoft** (`outlook`) — personal Microsoft accounts: `@outlook.com`, `@hotmail.com`, `@live.com`, `@msn.com`, and localised variants such as `@hotmail.co.uk`, `@live.in`, `@hotmail.fr`. Any other address registered as a personal Microsoft account also works, including custom domains. - **Zoho Mail** (`zoho`) — Zoho-hosted mailboxes, including custom domains **How it works:** 1. Call `POST /v4/inbox/connect` to get an OAuth URL 2. Redirect user to the OAuth URL for consent 3. User is redirected back to your `redirect_uri` with an encrypted `inbox_token` 4. Use the token to list/fetch CAS files from their inbox (`/v4/inbox/cas`) 5. Files are uploaded to temporary cloud storage (URLs expire in 24 hours) **Security:** - Read-only access (we cannot send emails) - Tokens are encrypted with server-side secret - User can revoke access anytime via `/v4/inbox/disconnect` - name: Inbound Email description: > Create dedicated inbound email addresses for investors to forward their CAS statements. **Use Case:** Your app wants to collect CAS statements from users without requiring OAuth or file upload. **How it works:** 1. Call `POST /v4/inbound-email` to create a unique inbound email address 2. Display this email to your user: "Forward your CAS statement to ie_xxx@import.casparser.in" 3. When user forwards a CAS email, we verify sender authenticity (SPF/DKIM) and call your webhook 4. Your webhook receives email metadata + attachment download URLs **Sender Validation:** - Only emails from verified CAS authorities are processed: - CDSL: `eCAS@cdslstatement.com` - NSDL: `NSDL-CAS@nsdl.co.in` - CAMS: `donotreply@camsonline.com` - KFintech: `samfS@kfintech.com` - Emails failing SPF/DKIM/DMARC are rejected - Forwarded emails must contain the original sender in headers **Billing:** 0.2 credits per successfully processed valid email - name: Contract Note Parser description: >- Endpoints for parsing Contract Note PDF files from various SEBI brokers like Zerodha, Groww, Upstox, ICICI etc. - name: Authorization description: | Endpoints for checking API quota and credits usage. These endpoints help you monitor your API usage and remaining quota. - name: Portfolio Connect description: > Endpoints for managing access tokens for the Portfolio Connect SDK. Use these to generate short-lived `at_` prefixed tokens that can be safely passed to frontend applications. Access tokens can be used in place of API keys on all v4 endpoints. - name: Agent Auth description: > Endpoints for coding agents to obtain API keys via a browser-based approval flow. **How it works:** 1. Agent generates a random token locally (e.g. `openssl rand -hex 32`). No API call needed. 2. Agent asks the user to open `https://app.casparser.in/agent-auth?token=&client_name=` 3. User signs in via the browser and clicks Approve. 4. Agent polls `GET /v1/agent-auth/token/{token}` every 5 seconds until the key is delivered. **Security:** - Token must be 16-128 characters (recommended: 64 hex chars / 256 bits) - Approved keys are delivered once (one-shot) and then deleted - Tokens expire after 10 minutes if not approved - name: KYC description: > Endpoints for verifying KYC (Know Your Customer) status of Indian investors. **Data source:** CVL KRA public inquiry portal (cvlkra.com), which aggregates records from all five SEBI-registered KRAs: CVL, NDML, CAMS, Karvy, and KFin. **Status normalization:** Raw CVL portal strings are normalized into clean enums. See the `kyc_status` property on `KycPanStatusResponse` for the full list. **Credits:** 0.25 per successful lookup. Failed lookups are not billed. - name: Verification description: | Verify the regulatory registration of a financial intermediary — a yes/no check rather than a directory search. - **`/v1/verify/sebi`** — any SEBI-registered intermediary (Investment Adviser, Research Analyst, Portfolio Manager, Stock Broker, Mutual Fund, AIF, and more). Send a `registration_number` and the category is auto-detected from its sequence; or send a `name` with an explicit `type`. - **`/v1/verify/mfd`** — AMFI mutual-fund distributors by ARN, including a screen against AMFI's suspended / terminated / terminated-EUIN lists. A "not found" result is a successful verification (HTTP 200, `verified: false`) and is billed. Upstream failures surface as 5xx and are not billed. **Credits:** 0.25 per successful verification. paths: /v1/verify/mfd: post: tags: - Verification summary: Verify an AMFI mutual-fund distributor (ARN) description: | Verify a mutual-fund distributor by ARN.
