How this service works
Fill a PDF form using facts found in supporting documents. Also: fill a PDF form from DOCX, spreadsheets, images, JSON, or other documents; pre-fill a government form from supporting paperwork; complete an application from a resume or company details; extract answers from context documents into a form. Price scales with page count; this 402 carries the exact amount for the PDF sent.
Output
Returns a JSON object containing a job_id (UUID), a quote_id (UUID), and a status_url pointing to the job status endpoint where the completed filled PDF can be retrieved once processing finishes.
Example use cases
Automated contract generation for SaaS
“I have a standard NDA PDF and a list of client details — company name, address, and signatory — can you fill out the NDA form for each client and return the completed PDFs?”
Government form submission prep
“Take this IRS W-9 PDF form and fill it in with my vendor's details: business name TechCorp LLC, tax classification S-Corp, and EIN 98-7654321, then give me the filled form.”
Insurance application document flow
“We have an insurance application PDF and the applicant's information from our database — can you populate all the form fields and return the finished application document?”

Side effects
- Invalid or non-fillable PDF input returns an error
- Missing required body fields (type, method, bodyType, body) cause a 400 validation error
- Payment not completed or insufficient funds results in a 402 response
- Large or complex PDFs may take longer and status must be polled via status_url
- Malformed JSON body type causes parsing failure
- Unsupported HTTP method (not POST/PUT/PATCH) rejected
