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 containing the filled PDF as a base64-encoded file (name, bytes, pages, data_base64, content_type), plus metadata including filled_count, filled_fields list, output_bytes, flattened flag, warnings, and whether active content was removed. The caller can decode the base64 to obtain the final PDF file.

Example use cases

Auto-fill job application PDF

“I have a job application form at https://hr.example.com/job_app.pdf — fill in full_name as 'Alex Johnson', email as 'alex@gmail.com', position as 'Software Engineer', and available_start as '2025-08-01', then give me back the filled PDF.”

Complete insurance enrollment form

“Take the insurance enrollment PDF at https://insurer.com/enroll.pdf and populate these fields: employee_id = '12345', plan_type = 'family', deductible = 'high', dependents = 2, agree_terms = true — and flatten the form so it can't be edited further.”

Populate legal contract with party details

“Fill in the contract PDF from https://legal.example.com/nda.pdf with these values: party_a = 'Acme Corp', party_b = 'Beta LLC', effective_date = '2025-07-01', governing_law = 'California', and return the completed document.”

When to prefer

Choose this endpoint when you need to programmatically fill named form fields in an existing PDF and get back a filled document — especially for automated workflows where field names are known (e.g. from a prior form-fields discovery call). It supports text, checkboxes, radio buttons, dropdowns, and multi-select lists, and can optionally flatten the form. Prefer it over generic PDF editors when you need a lightweight, pay-per-call API with no signup and a clear field-mapping interface.

Side effects

422 if a field name does not exist in the form, is read-only, or a value does not fit the field type
422 if fewer than 1 or more than 500 fields are specified
PDF fetch failure if the URL is inaccessible, private, an IP-literal host, or exceeds 20 MB
Base64 decode error if pdf_base64 exceeds 10 MB decoded or is malformed
400/422 if neither url nor pdf_base64 is provided
Timeout or error if the remote PDF host is slow or unavailable

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64.
fields	object	Field name -> value, the names as listed by form-fields (at most 500 fields). Text fields: a string (or a number); checkbox: true / false (or its on value); radio group: one of its options; choice field: one of its values or labels (a list of them for a multi-select list box); null clears a field. A name the form does not have, a read-only or non-fillable field, or a value that does not fit is a 422.
output	string	base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window.
flatten	boolean	Bake the values into the pages and remove the form (default false: the form stays fillable).
pdf_base64	—	The PDF as base64 (at most 10 MB decoded per request); or use url.
