Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get SRN statuses from My Application” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www.mca.gov.in/get_srn_statuses",
    "input": {
      "status": "Resubmission"
    }
  }'

{
  "status": "completed",
  "data": {
    "applications": [
      {
        "srn": "AB0004127",
        "form": "AOC-4",
        "company": "Acme Industries Private Limited",
        "status": "Resubmission"
      },
      {
        "srn": "AB0003958",
        "form": "MGT-15",
        "company": "Northwind Logistics LLP",
        "status": "Resubmission"
      }
    ],
    "count": 2
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

MCA21’s own options

The Ministry's help pages document no API for filers. V3 forms are filled online in the portal, saved as drafts if needed, and tracked by SRN under My Application. For XBRL filings the Ministry publishes a validation tool and a schema address for software vendors, and fees can be paid online or offline by eChallan.

Signing in to MCA21

MCA21 asks for a User ID (the CIN, LLPIN or FCRN for a company or LLP, an email address for other users) and a password. When a Business User signs in, an OTP is sent to the registered mobile and email address. With Fous you sign in once through MCA21's own sign-in with your own account: the login is sealed with AES-256, two-step sign-in by emailed code is handled, and an expired session is signed back in.

Worth knowing

Register as a Business User

A Registered User can view and file only RUN-LLP, FiLLiP, RUN-Co and SPICe forms. Other forms need the Business User category with a role, such as director by DIN or professional by PAN and membership number.

Signing a form still needs your DSC

After you submit a web form, its PDF is downloaded, you affix your DSC in Adobe, and you upload it against the SRN with Upload PDF. The DSC must be associated with your user ID.

One session per account

MCA21 ends any ongoing session for an account when that account signs in again. A scheduled run that signs in with your account ends a colleague's browser session on the same User ID.

Old V2 filings follow the old User ID

SRNs filed in V2 appear under My Application only if you sign in to V3 with the same V2 User ID and password. A new V3 account with a new email shows a blank history.
