Clearout API
★ Only Publicly Available OpenAPI DocumentData EnrichmentContact Enrichmentbearer9 EndpointsREST
For Agents
Verify emails, find professional emails by name and domain, reverse-lookup LinkedIn profiles or domains, and autocomplete company names through a single bearer-authenticated API.
Use for: I need to find a contact's professional email by name and company, Verify whether an email address is real and safe to send to, Look up a LinkedIn profile and get the associated email and company, Find the company domain for a given organisation name
Not supported: Does not handle email sending, CRM record management, or outreach automation — use for email verification, email discovery, and contact enrichment only.
Jentic publishes the only available OpenAPI specification for Clearout API, keeping it validated and agent-ready. Clearout combines email verification, email finder, reverse lookup, and company autocomplete into a single API for cleaning lists and enriching contact records. Synchronous endpoints handle individual lookups while batch endpoints process larger jobs asynchronously and return list IDs to poll. Reverse lookup operations resolve LinkedIn profiles, email addresses, or domains back to associated company and contact data.
Install Jentic One Beta
Connect the Clearout API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Clearout 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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | 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 Clearout API.
Verify a single email address with detailed deliverability and risk signals
Run bulk email verification jobs and check completion status by list ID
Find professional email addresses for a person at a specific company domain
Reverse lookup a LinkedIn profile URL to retrieve contact and company data
Reverse lookup an email or domain to surface organisation details
Autocomplete company names to canonical domains for downstream enrichment
Use Cases
Patterns agents use Clearout API for, with concrete tasks.
★ Outbound Sales Email Discovery
Find verified work emails for a target list of prospects by combining Clearout's email finder with instant verification. Sales teams provide a list of names and company domains, Clearout returns candidate addresses with confidence scores, and verification flags any risky or undeliverable hits before outreach. Typical workflows enrich a few hundred prospects in minutes via the bulk endpoint.
Call POST /email_finder/instant with first name, last name, and domain, then pass the returned email to POST /email_verify/instant and only forward addresses with a positive verification verdict.
LinkedIn-to-Email Enrichment
Convert a LinkedIn profile URL into a professional email and associated company record via Clearout's reverse lookup endpoints. Recruiters and BDRs use this to bridge from LinkedIn searches to outreach without manual research. The lookup returns structured data including current title and company so it can be written straight to a CRM record.
Call GET /reverse_lookup/linkedin with the prospect's profile URL and write the returned email, title, and company into a CRM contact record.
List Hygiene for Marketing Sends
Clean a marketing list before a send by uploading it to Clearout's bulk verification endpoint, polling for status, and removing addresses flagged as undeliverable, role-based, or risky. The bulk flow scales to lists that are too large for synchronous verification and returns deliverability plus quality signals per address.
Submit the list via POST /email_verify/bulk, poll GET /email_verify/bulk/{list_id} until the job completes, and remove every address whose status is invalid or risky from the marketing platform.
Company Domain Resolution
Resolve a free-text company name typed by a user or extracted from a form into the canonical web domain using Clearout's autocomplete endpoint. This is useful before email finding (which requires a domain) and for deduplicating CRM records that store the same company under different names.
Call GET /public/companies/autocomplete with the user-entered company name and select the top match's domain to use in subsequent email finder calls.
AI Agent Lead Enrichment Pipeline
Allow an AI agent to enrich raw leads end-to-end: resolve company domain, find candidate emails, verify deliverability, and reverse-lookup any LinkedIn URLs supplied with the lead. Through Jentic the agent calls each Clearout operation by intent rather than browsing docs, and the bearer token stays in the Jentic vault.
Search Jentic for 'find professional email', then chain autocomplete, email finder, and email verification operations to produce a verified-contact record for each input lead.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Clearout bearer tokens are stored encrypted in the Jentic vault. Agents execute Clearout operations via Jentic's scoped access — the JWT never appears in the agent's prompt or context.
Intent-based discovery
Agents search Jentic for intents like 'find a professional email' or 'reverse lookup linkedin profile' and receive the matching Clearout operation with its input schema, ready to execute.
Time to first call
Direct Clearout integration: 1-2 days to wire auth, finder, verifier, and bulk polling. Through Jentic: under 30 minutes — search, load schema, execute.

FAQs
Specific to using Clearout API through Jentic.
Why is there no official OpenAPI spec for Clearout API?
Clearout does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Clearout API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Clearout API use?
Clearout uses HTTP bearer token authentication with a JWT format. The token is sent in the Authorization header. When called through Jentic, the token is stored encrypted in the Jentic vault and is never exposed to the agent's prompt context.
Can I find someone's email address with the Clearout API?
Yes. Call POST /email_finder/instant with first name, last name, and a company domain to retrieve a candidate professional email along with a confidence indicator. For lists, use POST /email_finder/bulk and poll the resulting list ID for completion.
Can the Clearout API resolve a LinkedIn profile to an email?
Yes. Call GET /reverse_lookup/linkedin with the LinkedIn profile URL and Clearout returns the associated email and company data when available. This is useful for converting LinkedIn search results into outreach records.
What are the rate limits for the Clearout API?
Rate limits are not declared in the public OpenAPI spec and are governed by the credit plan attached to your Clearout account. Bulk endpoints queue server-side, so the practical limit for large jobs is plan credits rather than per-second throughput.
How do I verify and find emails through Jentic?
Search Jentic for 'find professional email' or 'verify email deliverability' and Jentic returns the matching Clearout operation with its input schema. Run pip install jentic, then await client.search, await client.load, await client.execute to chain finder and verification calls.
