For Agents
Identify accounts behind website traffic, enrich companies and people with firmographic and contact data, and score contacts on buying intent — all from the 6sense intelligence graph.
Use for: Find the company behind an anonymous visitor on our marketing site, Enrich this company record with industry, revenue, and employee count, Look up verified email and phone for a named contact at a target account, Search for vice presidents of marketing at companies with over 1000 employees
Not supported: Does not handle email sending, ad campaign delivery, or CRM record management — use for company and people enrichment, search, and intent scoring only.
Jentic publishes the only available OpenAPI specification for 6sense API, keeping it validated and agent-ready. The 6sense API exposes the data and intelligence services behind 6sense's account-based marketing platform across eight endpoints covering company identification, firmographic enrichment, people enrichment, person scoring, people search, and the search dictionary. Marketing and revenue teams use it to identify anonymous website visitors, enrich CRM records with firmographics and contact data, and feed buying-stage scores into orchestration tools. Authentication is an API token issued from a 6sense account.
Install Jentic One Beta
Connect the 6sense API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the 6sense 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 6sense API.
Identify the company behind an anonymous website visitor using domain or IP signal
Enrich a company record with firmographics including revenue band, employee count, and industry
Enrich a person record with verified email, phone, and current employer
Score a contact on buying-stage and intent within the 6sense model
Search 6sense's people graph by attributes such as title, function, and seniority
Look up the dictionary of supported person and company attributes for query construction
Use Cases
Patterns agents use 6sense API for, with concrete tasks.
★ Identify Anonymous Website Visitors at Account Level
Marketing teams running an account-based program use 6sense to deanonymize traffic by domain or IP and route the resulting account to sales when it matches the ICP. The /v3/company/details and /v1/enrichment/company endpoints return firmographics for matched domains and the platform exposes its proprietary buying-stage signal alongside. End-to-end integration into a website tag and CRM is typically three to five days.
Call POST /v1/enrichment/company with the visitor's domain, then route any match with revenue over $50M and matching industry to the SDR queue.
Contact Enrichment for Outbound Sales
Sales operations teams that run outbound campaigns enrich imported leads with verified email and phone via 6sense before passing them to outreach tools. The /v2/people/enrichment and /v2/people/full endpoints return contact and employer data, replacing slow manual lookups in LinkedIn or other point tools. Bulk enrichment of a 5,000-row list typically completes in under thirty minutes.
For each imported lead, call POST /v2/people/enrichment with first name, last name, and company domain and capture the returned email, phone, and current title.
Buying-Stage Scoring for Orchestration
Revenue operations teams pipe 6sense buying-stage scores into orchestration platforms so that contacts moving from awareness to consideration are routed to higher-touch plays. The /v2/people/score endpoint returns the model output for a given contact, while /v2/search/people lets the team build cohorts from intent attributes. Pipeline integration with a marketing automation tool takes around a week to ship.
Call POST /v2/people/score for a list of contacts, filter the response to those at 'Decision' stage, and add them to the high-touch nurture campaign.
AI Agent Account Research via Jentic
An AI sales-research assistant connected through Jentic can run /v3/company/details and /v2/search/people calls to build a target-account briefing in seconds. Jentic handles the API token in the vault and exposes operations by intent, so the agent can answer 'tell me about Acme Corp and find their head of marketing' in a single conversation. End-to-end response time is under thirty seconds per account.
Search Jentic for 'enrich a company by domain', load /v3/company/details for acme.com, then load /v2/search/people for the title 'VP of Marketing' at that company and return both.

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
6sense API tokens are stored encrypted in the Jentic vault (MAXsystem) and attached as an apiKey credential at execution time. Agents receive scoped access — the raw token never enters the prompt or output.
Intent-based discovery
Agents search Jentic with intents like 'enrich a company by domain' or 'score a contact on buying intent' and Jentic returns the matching 6sense operation with its input schema, so the agent calls the right endpoint without reading the developer portal.
Time to first call
Direct integration with the 6sense API takes three to five days for an account identification or enrichment flow including auth, response handling, and CRM mapping. Through Jentic the same call is reachable in under thirty minutes.

FAQs
Specific to using 6sense API through Jentic.
Why is there no official OpenAPI spec for 6sense API?
6sense publishes HTML developer documentation but does not distribute a downloadable OpenAPI specification for direct ingestion. Jentic generates and maintains this spec so AI agents and developers can call 6sense through 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 6sense API use?
The API uses an API token issued from a 6sense account, supplied as an apiKey credential on each request. When called through Jentic the token is stored encrypted in the vault and attached at execution time, so it never appears in the agent's prompt context.
Can I identify the company behind an IP address with the 6sense API?
Yes. Call POST /v1/enrichment/company with the visitor's domain or IP signal. The response includes the matched company along with firmographics such as industry, revenue band, and employee count when 6sense has high-confidence resolution.
What are the rate limits for the 6sense API?
6sense does not publish a single numeric rate limit; limits depend on the customer's contract tier and endpoint. Treat the API as quota-based, batch enrichment requests through /v2/people/enrichment where possible, and back off on HTTP 429 responses with the Retry-After header.
How do I enrich a company by domain through Jentic?
After running pip install jentic and setting JENTIC_AGENT_API_KEY, search Jentic for 'enrich a company by domain', load POST /v3/company/details, and execute it with the target domain. Jentic injects the 6sense token automatically.
Does the 6sense API return buying intent signals?
The /v2/people/score endpoint returns 6sense's buying-stage signal for a given contact. The score is the platform's proprietary model output combining intent, fit, and engagement signals — it is not a raw keyword feed.
