For Agents

Generate filled PDFs from templates, collect e-signatures via data requests, and merge multiple submissions into combined documents. Authentication is HTTP Basic with an API token ID and secret.

Quickstart

Get started with DocSpring API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"generate a filled PDF from a template"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with DocSpring API API.

Generate filled PDFs by submitting JSON data against a versioned template

Combine multiple submissions into a single merged PDF via combined_submissions

Collect signatures and structured input from end users through data_requests with tokenised links

Add, move, and rename PDF templates organised in folders

Use for: I need to generate a filled PDF from a contract template with customer data, I want to collect a signature on a rental agreement and download the signed PDF, Merge five filled invoice PDFs into a single combined submission, List all submissions for a given template in the last 30 days

Not supported: Does not handle PDF OCR, scanned-document extraction, or invoice parsing — use for template-based PDF generation and e-signature collection only.

DocSpring is a PDF generation and electronic signature service that lets developers fill out, sign, and merge PDF templates programmatically. The API exposes 40 endpoints covering template management, submissions, combined submissions for batch PDF generation, data requests for collecting signatures, and folder organisation. It supports HTML-to-PDF rendering, cached uploads, and versioned templates so teams can publish changes without breaking existing integrations.

Use Cases

Patterns agents use DocSpring API API for, with concrete tasks.

★ Automated Contract Generation

Fill PDF contract templates with customer data from a CRM and return a signed, finalised document. DocSpring handles field mapping, conditional logic, and version control so the same template can be reused across hundreds of contracts. Submissions complete in seconds and the API returns a permanent download URL for the generated PDF.

POST /submissions with template_id and a data payload of customer name, address, and contract value, then poll the returned submission for state=processed and download the file_url

E-Signature Collection

Send a data request link to a client, collect their input and signature, then receive the completed PDF back. DocSpring generates a tokenised URL per recipient, tracks events like opened and signed, and finalises the submission once all required fields are completed. Useful for onboarding flows that need legally formatted PDFs.

Create a data_request for template_id tpl_123 with the recipient email, fetch the resulting tokens, and email the signing URL to the client

Batch PDF Reporting

Generate hundreds of personalised PDFs in one API call by submitting a batch. DocSpring processes submissions in parallel and exposes a single batch ID that resolves to the merged combined_submission. Common for monthly statements, invoices, and certificate runs where each output is structurally identical but data-specific.

POST /submissions/batches with an array of 200 submissions, each carrying a customer_id and statement payload, then download the batch zip when state=processed

AI Agent Document Workflow

An AI agent fills a tax form template by reading values from a user's uploaded receipts, submits it through DocSpring via Jentic, and returns the finalised PDF link in chat. The agent never handles the API token directly, calls a single mcp tool, and gets a typed response that includes the download URL.

Search Jentic for 'generate a filled PDF', load the DocSpring create-submission schema, execute with template_id and the parsed receipt fields, and return the download URL

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

DocSpring API Token ID and Secret are stored encrypted in the Jentic vault. Agents receive a scoped execution token — the raw HTTP Basic credentials never enter the agent's context, so prompt injection cannot leak them.

Intent-based discovery

Agents call Jentic search with intents like 'generate a filled PDF' or 'collect a signature' and Jentic returns the matching DocSpring operations with their input schemas, so the agent can call the right endpoint without browsing docs.

Time to first call

Direct DocSpring integration: 1-2 days for auth, schema mapping, and polling logic. Through Jentic: under 30 minutes — search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

PDFMonkey

PDFMonkey generates PDFs from Liquid HTML templates rather than fillable PDF forms

Choose PDFMonkey when the source is HTML and you want CSS-driven layout; choose DocSpring when the source is an existing PDF form with named fields.

Alternative

PDF.co

PDF.co provides PDF generation, OCR, parsing, and conversion in a single API

Choose PDF.co when the workflow needs OCR or extraction in addition to generation; choose DocSpring for clean template-based filling and signing.

Complementary

Typeform

Typeform collects structured form responses that can be piped into a DocSpring template

Use Typeform to gather the data, then forward the response to DocSpring to generate the final signed PDF.

FAQs

Specific to using DocSpring API API through Jentic.

What authentication does the DocSpring API use?

DocSpring uses HTTP Basic authentication with the API Token ID as the username and the API Token Secret as the password. Through Jentic, these credentials are stored encrypted in the vault and never enter the agent's context — the agent receives a scoped execution token instead.

Can I generate filled PDFs from a template with the DocSpring API?

Yes. POST to /submissions with a template_id and a data object whose keys match the template's field schema. The endpoint returns a submission resource that resolves to a downloadable PDF once state=processed.

What are the rate limits for the DocSpring API?

DocSpring does not publish hard rate limits in its OpenAPI spec; the documented production limit is around 50 requests per second per account, with higher quotas available on request. Batch submissions count as a single request regardless of the number of PDFs generated.

How do I collect a signature with the DocSpring API through Jentic?

Use Jentic search query 'collect a signature on a PDF', load the DocSpring data_requests schema, and execute POST /data_requests/{data_request_id}/tokens to mint a tokenised URL for each signer. Email the URL to the recipient and poll the data_request for the signed event.

Is the DocSpring API free?

DocSpring offers a free tier with a small monthly submission allowance and paid plans that scale by submissions per month. Pricing details and current limits are published at docspring.com/pricing.

How do I generate multiple PDFs at once with the DocSpring API?

POST to /submissions/batches with an array of submissions. Each item includes its own template_id and data payload, and the batch resolves to a combined PDF or per-submission downloads. This is the recommended path for monthly statement and invoice runs.
