For Agents
Send documents for e-signature, manage templates and contacts, embed signing into your app, and download signed PDFs and audit trails through BoldSign.
Use for: I need to send a contract for signature to two signers, Generate an embedded signing URL for my application, Download the signed PDF and audit log for a completed envelope, Send a reminder to a signer who has not yet signed
Not supported: Does not handle contract drafting, payment collection, or document storage outside the signature lifecycle - use for sending and managing e-signature workflows only.
BoldSign is an electronic signature platform from Syncfusion that lets businesses send, sign, and manage legally binding documents. The API exposes 84 endpoints covering documents, templates, contacts, brands, teams, sender identities, custom fields, and identity verification. Use it to send documents for signature, embed signing into your own application, build reusable templates, and download signed copies and audit trails. It also supports advanced flows like ID verification, prefill, and embedded designer URLs.
Install Jentic One Beta
Connect the BoldSign API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the BoldSign API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fboldsign.com%2Fboldsign" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fboldsign.com%2Fboldsign" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with BoldSign API.
Send a document for signature with one or more signers and an optional access code
Create reusable templates and dispatch documents from them, including merging multiple templates
Generate embedded URLs so signers can sign without leaving your application
Download the final signed PDF and the tamper-evident audit trail for compliance
Run identity verification on signers and retrieve the resulting verification report
Manage contacts, contact groups, and brands used to personalise signature requests
Send reminders, extend expiry, change recipients, or revoke a document mid-flight
Use Cases
Patterns agents use BoldSign API for, with concrete tasks.
★ Embedded Signing in a SaaS Product
Embed the signing experience directly inside your product so signers never leave the app. Create the document with /v1/document/createEmbeddedRequestUrl, render the returned URL in an iframe, and use /v1/document/getEmbeddedSignLink for subsequent signers. Removes the email round-trip and keeps users inside your branded experience.
POST /v1/document/createEmbeddedRequestUrl with one signer and the contract PDF, then return the embed URL to the frontend
Template-Driven Sales Contracts
Build a sales contract template once with placeholder fields, then dispatch personalised copies for each new deal. /v1/template/create stores the template, /v1/template/send fires it off with merged values, and /v1/template/mergeAndSend combines multiple templates into a single envelope. Sales ops teams use this to remove the copy-paste work of generating contracts.
POST /v1/template/send with templateId tmpl_5521 and the buyer's name, email, and contract value
ID Verification for High-Trust Documents
Require government ID verification before a signer can complete a sensitive document such as a loan or NDA. Generate the verification URL with /v1/identityVerification/createEmbeddedVerificationUrl, then pull the report via /v1/identityVerification/report once the signer has completed it. Useful for fintech, legal, and HR onboarding flows.
POST /v1/identityVerification/report for documentId doc_8821 and signer email signer@example.com
Compliance Archive and Audit Trail
Pull the signed PDF and audit log for every completed document and archive both into your compliance store. /v1/document/download returns the signed file and /v1/document/downloadAuditLog returns the tamper-evident trail. Required for regulated industries that need a defensible record of who signed what and when.
GET /v1/document/download and /v1/document/downloadAuditLog for documentId doc_8821 and store in s3://compliance/contracts/
AI Agent Document Workflow
An AI agent uses Jentic to discover BoldSign operations from natural-language requests, sends documents for signature, sends reminders, and pulls signed PDFs without ever holding the API key. The credential lives in your Jentic One instance while the agent runs the search-load-execute cycle for each step. Time-to-integration drops from days of API key plumbing to under an hour.
Search Jentic for 'send a document for signature', load the operation, and execute it with the contract file and signer list

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring BoldSign by hand means choosing between its Authorization bearer and X-API-KEY header schemes and mapping the document signature lifecycle yourself. Through Jentic you install once, import BoldSign from the API Directory, store the API key once, and your agent calls it.
Permission scoping
BoldSign's document actions carry the document identifier in the request body or query, not a fixed URL path segment, so limit the agent to the operations it needs, such as sending a document or downloading a signed copy. You choose that set, so revoking a document is not included unless you add it.
Credential isolation
Your BoldSign API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'send a document for signature' or 'download a signed PDF', and Jentic returns the matching BoldSign operation with its input schema so the agent calls the right endpoint without browsing the BoldSign reference.

FAQs
Specific to using BoldSign API through Jentic.
What authentication does the BoldSign API use?
BoldSign supports two API key schemes sent via header: an X-API-KEY header with the raw API key, or an Authorization header with the value 'Bearer <token>'. Through Jentic the key is stored encrypted in the vault and the agent never sees the raw value.
Can I embed signing into my application with the BoldSign API?
Yes. Use POST /v1/document/createEmbeddedRequestUrl to get a send URL for embedding the request flow, and GET /v1/document/getEmbeddedSignLink to retrieve a sign URL for each signer. Render either inside an iframe in your application.
How do I send a document for signature through Jentic?
Search Jentic for 'send a document for signature', load the POST /v1/document/send operation schema, then execute it with the file, signer list, and any access code. Jentic handles the API key automatically.
What are the rate limits for the BoldSign API?
BoldSign meters usage in API credits rather than fixed per-minute limits. Use GET /v1/plan/apiCreditsCount to read your current credit balance and pace requests accordingly. Different operations consume different credit amounts.
Can I download the signed PDF and audit log?
Yes. GET /v1/document/download returns the final signed PDF and GET /v1/document/downloadAuditLog returns the tamper-evident audit trail. Both accept the documentId as a query parameter.
Does the BoldSign API support signer identity verification?
Yes. Use POST /v1/identityVerification/createEmbeddedVerificationUrl to require ID verification before signing, then POST /v1/identityVerification/report to retrieve the verification result for that signer.
Can I limit what my agent is allowed to do with the BoldSign API?
Yes. Because you self-host Jentic One, your own rules decide which BoldSign operations and credentials the agent may use, and you grant only the ones it needs, such as POST /v1/document/send to send a document or GET /v1/document/download to fetch a signed copy. BoldSign carries the document identifier in the request body or query rather than a fixed URL path, so you scope access at the operation level. If you do not add POST /v1/document/revoke, the agent cannot revoke a document, and your stored API key is injected only at execution time so the agent never sees it.
