For Agents
Create, issue, and send digital certificates and badges, apply design and credential templates, and track recipient interactions through the Certifier API.
Use for: Create a new digital credential for a recipient, Issue a credential and send it by email, Search for credentials issued to a recipient, List the design templates available to my account
Not supported: Does not handle identity verification, exam proctoring, or course delivery. Use for issuing and sending digital certificates and badges only.
The Certifier API creates, issues, and sends digital credentials such as certificates and badges to recipients. It applies design templates and credential templates to control how each credential looks and what it contains, and can create, issue, and send a credential in a single call. Credential search, listing, and recipient interaction records round out the issuing workflow.
Install Jentic One Beta
Connect the Certifier API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Certifier 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%2Fcertifier.io%2Fcertifier" | 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%2Fcertifier.io%2Fcertifier" | 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 Certifier API.
Create, issue, and send digital credentials to recipients
Issue and deliver a credential in a single create-issue-send call
Search and list issued credentials
Define credential templates that set each credential's content
Apply design templates to brand a credential
Record recipient interactions with issued credentials
Use Cases
Patterns agents use Certifier API for, with concrete tasks.
★ AI Agent Credential Issuing
An AI agent connected through Jentic can award a credential on request: it creates the credential from a template for a named recipient, issues it, and sends it to their email. Certifier can even combine those steps into a single create-issue-send call, so the agent completes the award in one action.
Create a credential from a template for a named recipient, issue it, and send it to their email
Course Completion Certificates
Reward learners at the end of a course by issuing a certificate tied to a credential template. Certifier populates recipient details from the issue request and delivers the certificate, which suits automated completion flows triggered from a learning platform.
Issue a completion certificate from a program template to a learner and send it to their email
Branded Credential Design
Keep credentials on-brand by applying a design template to each one. Certifier exposes design templates and credential templates so an integration can select the right look and content before issuing.
List the available design templates and create a credential template that uses a chosen design
Credential Lookup and Verification Records
Answer recipient questions by searching issued credentials and reading their recorded interactions. Certifier lists credentials and credential interactions so a support workflow can confirm what was issued and whether it was viewed.
Search credentials for a recipient email and return each credential's status and recorded interactions

What agents get from Jentic-routed access to this vendor.
Setup
Wiring Certifier by hand means handling its bearer-token auth and tracking the credential, design, template, and interaction paths yourself. Through Jentic you install once, import Certifier from the API Directory, store the token once, and your agent calls it.
Permission scoping
You choose which Certifier operations the agent may call, such as creating and issuing credentials, so operations like deleting credentials or templates are not included unless you add them.
Credential isolation
Your Certifier access token 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 'issue a credential' or 'send a certificate', and Jentic returns the matching Certifier operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Certifier API through Jentic.
What authentication does the Certifier API use?
The Certifier API authenticates with a bearer access token sent in the Authorization header, per its OpenAPI spec. You create and manage tokens in the Certifier dashboard, and through Jentic the token is stored encrypted by your own Jentic One instance and injected at call time, so it never appears in the agent's prompt or logs.
Can I issue and send a certificate in one call with the Certifier API?
Yes. Alongside the separate create, issue, and send operations, the API offers a create-issue-send operation that produces a credential from a template, issues it, and delivers it to the recipient in a single request. This suits fully automated completion flows.
Is there a Certifier MCP server?
You do not need an MCP server to give your agent the Certifier API. Jentic connects it directly from the API Directory: import Certifier, store your token once, and your agent issues and sends credentials through the operations the API already exposes. Operations are discovered on demand, so no extra tool definitions are loaded into the agent's context.
Can I limit what my agent is allowed to do with the Certifier API?
Yes. Write a rule that allows only the operations the agent needs, for example creating and issuing credentials, and leave out operations like deleting credentials or templates. The agent can award credentials within those bounds, and every call it makes is logged.
How do I issue a credential through Jentic with the Certifier API?
Search Jentic for 'issue a credential', which returns the Certifier operation with its input schema, then supply the template and recipient details and the agent runs it. To run it on your own infrastructure, install Jentic One from its GitHub repo.
