Registry Verification

Overview

Registry Verification confirms a financial intermediary’s regulatory registration against the official public registers. Two endpoints, one job — a yes/no answer you can gate onboarding on:

POST /v1/verify/sebi — any SEBI-registered intermediary (Investment Adviser, Research Analyst, Portfolio Manager, Stock Broker, Merchant Banker, RTA, Mutual Fund, AIF, and more).
POST /v1/verify/mfd — an AMFI Mutual Fund Distributor by ARN, screened against AMFI’s suspended, terminated, and terminated-EUIN lists.

What you get:

A single verified boolean to gate on
A normalized registration_status (ACTIVE, EXPIRED, SUSPENDED, TERMINATED, NOT_FOUND)
The registrant’s name, validity, and category — straight from the regulator’s register

What you need:

A registration number (SEBI) or an ARN (AMFI). That’s it — the category is auto-detected.

A “not found” result is a successful verification: you get HTTP 200 with verified: false and registration_status: NOT_FOUND. It’s billed like any other lookup. Only genuine service errors return 5xx (and those are free).

Verify a SEBI intermediary

Send the registration number — the category is detected from its sequence. No need to tell us whether it’s an adviser, broker, or portfolio manager.

import requests

response = requests.post(
    "https://api.casparser.in/v1/verify/sebi",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={"registration_number": "INA000000888"},
    timeout=30,
)

data = response.json()

if data["verified"]:
    print(f"{data['name']} — {data['category_label']}, {data['registration_status']}")
else:
    print(f"Not verified — {data['registration_status']}")

Categories & auto-detection

/v1/verify/sebi covers every SEBI intermediary register. When you send a registration_number, the character after IN selects the category automatically — no type needed:

Prefix	Category	`type` slug
`INA`	Investment Adviser (RIA)	`investment-adviser`
`INH`	Research Analyst	`research-analyst`
`INP`	Portfolio Manager (PMS)	`portfolio-manager`
`INM`	Merchant Banker	`merchant-banker`
`INR`	Registrar & Share Transfer Agent	`registrar-transfer-agent`
`INB` `INE` `INF` `INZ`	Stock Broker	`stock-broker`

The remaining registers don’t encode a category in the number (funds, FPIs, trusts, etc.), so pass type explicitly. These are all supported:

`type` slug	Category
`mutual-fund`	Mutual Fund
`alternative-investment-fund`	Alternative Investment Fund (AIF)
`credit-rating-agency`	Credit Rating Agency
`custodian`	Custodian
`debenture-trustee`	Debenture Trustee
`venture-capital-fund`	Venture Capital Fund
`foreign-venture-capital-investor`	Foreign Venture Capital Investor
`foreign-portfolio-investor`	Foreign Portfolio Investor (FPI)
`kyc-registration-agency`	KYC Registration Agency (KRA)
`infrastructure-investment-trust`	Infrastructure Investment Trust (InvIT)
`real-estate-investment-trust`	Real Estate Investment Trust (REIT)
`esg-rating-provider`	ESG Rating Provider
`vault-manager`	Vault Manager

Short aliases are accepted anywhere a type is expected: ria, ia, ra, pms, broker, rta, mf, aif, cra, vcf, fvci, fpi, kra, invit, reit. type is also how you search by name (there’s no number to detect from), or override detection:

# Search by name — type is required when there's no registration number
requests.post(
    "https://api.casparser.in/v1/verify/sebi",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={"name": "Motilal Oswal", "type": "portfolio-manager"},
    timeout=30,
)

The registration number is authoritative. If you send both registration_number and name, the name is ignored — we never let a mismatched name turn a real registration into a false “not found”.

SEBI response

{
  "status": "success",
  "verified": true,
  "authority": "SEBI",
  "category": "investment-adviser",
  "category_label": "Investment Adviser (RIA)",
  "registration_number": "INA000000888",
  "name": "360 ONE Investment Adviser and Trustee Services Limited",
  "registration_status": "ACTIVE",
  "valid_from": "2014-01-22",
  "valid_till": null,
  "is_perpetual": true,
  "address": "IIFL Centre, Kamala Mills, Lower Parel, MUMBAI, MAHARASHTRA, 400013",
  "email": "advcompliance@example.com",
  "telephone": "0912345678",
  "contact_person": "Compliance Officer",
  "detected_by": "registration_number"
}

Every key is always present on a 200 response — null when it doesn’t apply (e.g. a NOT_FOUND result carries the same keys with nulls). Use verified as your gate.

Verify an AMFI distributor (ARN)

import requests

response = requests.post(
    "https://api.casparser.in/v1/verify/mfd",
    headers={"x-api-key": "YOUR_API_KEY"},
    json={"arn": "89762"},
    timeout=30,
)

data = response.json()
print(data["registration_status"])   # ACTIVE / SUSPENDED / TERMINATED / NOT_FOUND

The ARN — and the EUIN attached to it — is screened against AMFI’s adverse lists. A distributor who has been suspended or terminated for cause is reported as such, not merely “not found”:

{
  "status": "success",
  "verified": false,
  "authority": "AMFI",
  "category": "mutual-fund-distributor",
  "category_label": "Mutual Fund Distributor (ARN)",
  "arn": "89762",
  "name": null,
  "euin": null,
  "kyd_compliant": null,
  "registration_status": "SUSPENDED",
  "valid_from": null,
  "valid_till": null,
  "is_perpetual": false,
  "address": null,
  "pincode": null,
  "negative_list_hit": true,
  "negative_list": { "type": "suspended", "since": "May 26, 2006" }
}

Only an exact ARN matches. A partial or non-existent ARN returns NOT_FOUND — we never resolve a fuzzy search to some other distributor’s record.

An active distributor returns verified: true, kyd_compliant, and the ARN’s valid_from/valid_till. negative_list_hit is false and negative_list is null.

Adverse-list screening

Every ARN is checked against three AMFI lists. A hit populates negative_list and overrides registration_status:

`negative_list.type`	Source list	`registration_status`
`suspended`	ARN suspended from mutual fund business	`SUSPENDED`
`terminated`	ARN terminated	`TERMINATED`
`euin_terminated`	The EUIN attached to the ARN was terminated	`TERMINATED`

negative_list.since carries the effective date AMFI published (e.g. "May 26, 2006"). On an active record, three AMFI-specific fields matter:

kyd_compliant — the distributor’s Know Your Distributor (KYD) status. true when compliant.
euin — the Employee Unique Identification Number of the individual under the ARN.
valid_from / valid_till — the ARN’s current validity window (ARNs are renewed, never perpetual).

`registration_status` values

Status	Meaning	`verified`
`ACTIVE`	Currently registered and in good standing	`true`
`EXPIRED`	Registration validity end date has passed	`false`
`SUSPENDED`	On AMFI’s suspended list (see `negative_list`)	`false`
`TERMINATED`	On AMFI’s terminated / terminated-EUIN list	`false`
`NOT_FOUND`	No current registration in this register	`false`

SUSPENDED and TERMINATED are MFD-only. SEBI’s register lists current registrations, so a lapsed or cancelled SEBI registration simply reads NOT_FOUND.

Credit usage

Operation	Credits
Successful verification (found or not found)	0.25
Failed lookup (any 5xx)	0

Both endpoints bill under a single verify feature. The register the lookup hit (SEBI vs AMFI) is recorded on the usage event, so you can still break usage down by source.

Error handling

HTTP status	Cause	Action
`400`	Missing input, unknown `type`, or `name` without `type`	Fix the request body
`401`	Invalid or missing API key	Check the `x-api-key` header
`403`	`verify` not enabled on your plan, or quota exhausted	Check your plan / top up
`422`	Category couldn’t be detected from the registration number	Pass an explicit `type`
`500`	The verification service is temporarily unavailable	Retry with backoff

try:
    r = requests.post(
        "https://api.casparser.in/v1/verify/sebi",
        headers={"x-api-key": "YOUR_API_KEY"},
        json={"registration_number": "INA000000888"},
        timeout=30,
    )
    r.raise_for_status()
    data = r.json()
except requests.exceptions.HTTPError as e:
    if e.response.status_code == 500:
        print("Register unavailable — retry in a few seconds")
    else:
        raise
