Install Jentic One Beta

Connect the ClearBounce API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the ClearBounce 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%2Fclearbounce.net%2Fclearbounce" | sh

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%2Fclearbounce.net%2Fclearbounce" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic 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.

Use Cases

Patterns agents use ClearBounce API for, with concrete tasks.

★ Real-Time Signup Email Validation

Validate the email address a user enters at signup before creating their account, preventing fake accounts and reducing bounce rates on activation emails. ClearBounce's single-email endpoint returns a deliverability verdict synchronously so the signup form can reject or warn the user before submission. Integration sits inline in the signup flow and adds only a single API call per registration.

Call POST /api/v1/verify with the user-supplied email address and reject the signup if the response indicates the address is undeliverable.

Marketing List Cleanup

Clean a large existing email list before a marketing send by uploading it for bulk verification, polling until the job finishes, and downloading the results to remove undeliverable addresses. This protects sender reputation and improves deliverability rates without requiring per-row real-time calls. A list of tens of thousands typically completes within minutes to hours depending on size.

Upload a CSV of 10,000 email addresses to POST /api/v1/bulk/upload, poll GET /api/v1/bulk/{jobId} every 30 seconds until status is complete, then download results from GET /api/v1/bulk/{jobId}/results.

Lead Quality Scoring for Sales

Score inbound leads by checking their email address against ClearBounce before routing them to a CRM. Leads with verified addresses are prioritised in the sales queue while those with role-based or undeliverable emails are flagged or held back. The single-email endpoint runs in under a second so it fits inside webhook handlers or serverless lead-capture functions.

When a new lead webhook fires, call POST /api/v1/verify on the lead email and tag the CRM record as verified, risky, or undeliverable based on the response.

AI Agent Email Hygiene Workflow

Allow an AI agent to maintain email list hygiene as part of a wider outreach pipeline. The agent uploads a list, monitors the bulk job to completion, retrieves results, and updates the source CRM or marketing tool with the verdicts. With Jentic, the agent finds and calls all four ClearBounce operations from a single intent search rather than reading docs, and credentials stay in your Jentic One instance.

Search Jentic for 'verify email deliverability', execute the bulk upload operation with the contact list, poll the job until status is finished, and write the per-address results back into the CRM.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the ClearBounce API by hand means passing its API key in the Authorization header on every call to api.clearbounce.net and polling job ids for bulk verification yourself. Through Jentic you install once, import ClearBounce from the API Directory, store the key once, and your agent calls it.

Permission scoping

ClearBounce puts the job id in the URL path (/api/v1/bulk/{jobId}), so a rule can pin your agent to reading one bulk job: it can check that job and its results and nothing else. You choose the operations it may call, so single verify and bulk upload are not included unless you add them.

Credential isolation

Your ClearBounce 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 'verify an email' or 'check a bulk verification job in ClearBounce', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using ClearBounce API through Jentic.

Why is there no official OpenAPI spec for ClearBounce API?

ClearBounce does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call ClearBounce API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the ClearBounce API use?

ClearBounce uses API key authentication. The key is sent in the Authorization header on every request. When called through Jentic, the key is stored encrypted in your Jentic One instance and never enters the agent's context - agents receive scoped access to the operations only.

Can I verify emails in bulk with the ClearBounce API?

Yes. Upload a list of addresses to POST /api/v1/bulk/upload, which returns a job ID. Poll GET /api/v1/bulk/{jobId} until the status indicates completion, then download results from GET /api/v1/bulk/{jobId}/results. This pattern handles lists too large for synchronous verification.

What are the rate limits for the ClearBounce API?

The published OpenAPI spec does not declare explicit rate limits. Real-time verification calls return synchronously and bulk uploads queue server-side, so practical throughput is governed by your account plan. Check the ClearBounce dashboard or contact ClearBounce directly for the limits attached to your key.

How do I verify a single email address through Jentic?

Search Jentic for 'verify an email address', and the SDK returns the POST /api/v1/verify operation with its input schema. Load the schema, pass the email value, and execute. The full flow is: pip install jentic, then await client.search, await client.load, await client.execute.

Is the ClearBounce API free?

ClearBounce offers paid plans tied to verification volume. The API itself does not have a free public tier exposed in the spec; pricing and any free trial credits are managed in the ClearBounce dashboard at the time you provision an API key.

Can I limit what my agent is allowed to do with the ClearBounce API?

Yes. Jentic One is self-hosted, so your own rules decide which ClearBounce operations the agent may call and which credential it uses. Because ClearBounce puts the job ID in the URL path (/api/v1/bulk/{jobId}), you can pin the agent to a single bulk job, letting it check that job's status and download its results and nothing else. Single-email verify (POST /api/v1/verify) and bulk upload (POST /api/v1/bulk/upload) are excluded unless you explicitly add them, and your API key stays in your own instance rather than in the agent's context.

For Agents

Verify whether email addresses are deliverable using single-email checks or asynchronous bulk verification jobs. Returns a job ID for bulk uploads that the agent can poll for status and download.

Use for: I need to verify whether an email address is deliverable, Check whether a list of email addresses is valid before sending a campaign, Upload a CSV of leads for bulk email verification, Get the status of a bulk verification job I started earlier

Not supported: Does not handle email sending, SMTP delivery, or inbox monitoring - use for email address verification only.

Jentic publishes the only available OpenAPI specification for ClearBounce API, keeping it validated and agent-ready. ClearBounce is an email verification service that validates individual addresses in real time and runs bulk verification jobs against uploaded lists. Single-email checks return deliverability results synchronously, while bulk uploads return a job ID that can be polled for status and downloaded once complete. The API is suitable for cleaning marketing lists before sending and for inline checks during user signup flows.
