# Citiview PDF Form Tool

> Citiview PDF Form Tool is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Lists fillable fields of any PDF, fills them (text, checkboxes, dropdowns) with optional flattening, or merges up to 10 PDFs into one, returning the result as base64.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability citiview-pdf-form-tool-6f38d716
```

Example prompt: List all the fillable fields in this PDF form: https://example.com/application.pdf — then fill in the 'FirstName' field with 'Jane', 'LastName' with 'Doe', and check the 'AgreeToTerms' checkbox, then flatten it and give me the finished PDF.

## When to prefer this

Choose this endpoint when you need to programmatically inspect, fill, or merge PDF forms without a full document-processing pipeline. Ideal for automating form submissions, populating PDF templates with dynamic data, or combining multiple PDF documents server-side. Prefer this over general document-to-text endpoints when the output must remain a PDF (not plain text or HTML).

## Known failure modes

- Invalid or inaccessible PDF URL returns an error
- Malformed fields JSON causes a parsing failure
- More than 10 PDFs specified for merge exceeds limit
- Field names that don't exist in the PDF are silently ignored or error
- Non-PDF URLs may fail to parse as a form
- Network timeout on large PDFs

## How this service works

PDF forms: list the fillable fields of any PDF, fill them (text, checkboxes, dropdowns) and optionally flatten, or merge up to 10 PDFs into one. Returns the finished PDF as base64. Also callable as GET with the same fields as query parameters.

## Output

Returns a base64-encoded PDF string representing the result: a list of field names (for 'list' action), a filled and optionally flattened PDF (for 'fill' action), or a merged PDF combining up to 10 inputs (for 'merge' action).
