Web Form Extractor - Form Fields, Method & Action from URL

Web Form Extractor — every form's fields, method & action from a URL

Web Form Extractor lists every HTML form on a page with its action, method, encoding and each field's name, type, required flag and placeholder, at $0.001 per page on the Apify Free plan.

You give it	You get back	You pay (Free plan)
One URL or a list of up to 50 (25 by default)	ok, url, status, formCount, and per form: action, method, enctype, fieldCount, fields, hasPassword, hasEmail, hasFile	$0.001 per page

Pay per result only: no subscription, no start fee. An unreachable URL returns {ok:false, error} and is not charged. Paid Apify plans get Store discounts on the price above.

Example: try it in one click

The input form is already filled in with this example. Press Start and you get the output below.

{
  "url": "https://httpbin.org/forms/post"
}

Real output from that exact input (run on 2026-09-24; long arrays shortened to a few entries and long text cut for display):

[
  {
    "ok": true,
    "url": "https://httpbin.org/forms/post",
    "requestedUrl": "https://httpbin.org/forms/post",
    "status": 200,
    "formCount": 1,
    "forms": [
      {
        "action": "https://httpbin.org/post",
        "method": "post",
        "enctype": "application/x-www-form-urlencoded",
        "id": "",
        "name": "",
        "fieldCount": 12,
        "hasPassword": false,
        "hasEmail": true,
        "hasFile": false,
        "fields": [
          {
            "name": "custname",
            "type": "text",
            "required": false,
            "placeholder": "",
            "value": ""
          },
          {
            "name": "custtel",
            "type": "tel",
            "required": false,
            "placeholder": "",
            "value": ""
          }
        ]
      }
    ]
  }
]

Extract all forms on a web page with their action, method, enctype, and every field (name, type, required, placeholder, value) — plus quick flags for hasPassword, hasEmail, and hasFile. Built for security review, QA/automation mapping, and lead-form auditing. Single URL or bulk.

$0.001 per page. Failed fetches are recorded free.

What you get

• One record per page, listing every <form>.
• Per form: action, method, enctype, id, name, fieldCount, and a fields array.
• Per field: name, type, required, placeholder, value (left empty for password and hidden fields, and for fields named like a token, PIN or card number).
• Convenience flags: hasPassword, hasEmail, hasFile.
• Fail-soft: an unreachable URL returns {ok:false, error} and is never charged.

Input

{ "url": "https://github.com/login", "urls": ["https://example.com/contact"], "maxUrls": 25 }

Output (real run, 2026-08-07)

      "method": "post",
      "enctype": "application/x-www-form-urlencoded",

Pricing — $0.001 per page

$0.001 per page scanned on the Apify Free plan, billed as the page-scanned event. Paid Apify plans pay less ($0.00093 Bronze, $0.00087 Silver, $0.0008 Gold, $0.00073 Platinum, $0.00067 Diamond). No start fee. Failed fetches are recorded free. A page with no forms was scanned successfully and is charged.

Limits (honest ones)

• Reads the server HTML; forms injected by JavaScript after load are not seen (no headless browser).
• Field action is absolutized to the page URL when relative.
• maxUrls is capped at 50 per run (25 by default).

FAQ

• Does it submit forms? No — it only reads and describes them.
• Does it run JavaScript? No — server HTML only.
• Can it flag login/upload forms? Yes — hasPassword, hasEmail, and hasFile make those easy to filter.
• What about a dead URL? You get an {ok:false, error} record, uncharged.
• Does it return what users typed into a form? No. It reads the page's HTML as served, so value is only a default value written into the page, and it is left empty for sensitive fields.

Use from code or AI agents

curl -X POST "https://api.apify.com/v2/acts/EliAI~webpage-forms-extractor/runs?token=YOUR_APIFY_TOKEN" \
  -H 'content-type: application/json' \
  -d '{"url":"https://github.com/login"}'

Callable as an agent tool through the Apify MCP server (mcp.apify.com).

For AI agents

This Actor is built to be called by software, not just by people.

• Mount it directly as an MCP tool — no Store search, no ranking, just this one tool: https://mcp.apify.com/?actors=eliai/webpage-forms-extractor
• Or call it over HTTP and get the results in the same request: POST https://api.apify.com/v2/acts/eliai~webpage-forms-extractor/run-sync-get-dataset-items
• Costs are predictable before you call. Pricing is pay-per-event (see Pricing above), so an agent can budget a run in advance instead of discovering the bill afterwards.
• Send only the field you mean. If you pass the bulk field, it is used on its own; the single-value field is a fallback, never merged into your request. You are charged for the items you sent and nothing else.

Who uses it

• Penetration testers listing a site's forms, their actions and password or file fields
• QA automation engineers mapping form field names before writing end-to-end tests
• Marketing ops teams auditing lead forms across landing pages for required fields
• Accessibility reviewers finding inputs without names or placeholders
• Scraper developers learning a form's method and fields before automating submissions
