How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns a JSON object listing all interactive form fields found in the PDF. Each field includes its name, page number, type (text, checkbox, radio, choice), current value, required and read-only flags, optional description, and for choice/radio fields the available options. Also includes top-level flags: whether the PDF uses XFA, whether it has any form at all, total field count, page count, input byte size, and whether the output was truncated.
Example use cases
Auto-fill agent form discovery
“Before filling out this PDF application form, can you tell me all the fields it contains, what types they are, and which ones are required? The form is at https://gov.example.com/permit-application.pdf”
PDF form validation pipeline
“I have a base64-encoded PDF contract form — can you extract all its form fields, their types, and current values so I can verify it's been filled in correctly before submission?”
Form inventory for document processing
“We just received a new vendor PDF form. Can you list every field in it — names, types, dropdown options, and which are mandatory — so I can map them to our internal data fields?”
Technical details
Endpoint
POSThttps://tanod.dev/v1/pdf/form-fields?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically discover the structure of a fillable PDF form before attempting to fill it, validate it, or map its fields to external data. It is purpose-built for PDF form introspection and returns rich per-field metadata including types, options, and required flags — unlike generic PDF text extractors which don't surface form field semantics.
Side effects
- PDF URL is inaccessible, private, or points to an internal/IP-literal host — request refused
- PDF exceeds 20 MB (URL) or 10 MB decoded (base64) size limit — rejected
- Neither url nor pdf_base64 provided — validation error
- PDF is not a valid or parseable PDF — parsing error
- PDF has no interactive form fields — returns has_form: false with empty fields array
- Network timeout fetching the PDF URL — fetch error
