Let AI Enrich Your Data
Give Claude, ChatGPT, or any AI direct access to your lead list. No credits. No walled gardens. Just results.
ListPlus provides a secure REST API that turns any AI model into a data enrichment engine. Give Claude or ChatGPT your API endpoint, and it can query your list, research each contact using the full internet, fill in missing fields, validate data quality, and tag records — all with enterprise-grade guardrails. No CSV exports. No enrichment credits. No proprietary AI limitations. Your data + any AI = instant enrichment.
The Problem: Enrichment Tools Are Walled Gardens
Today's enrichment tools trap you in their ecosystem. Clay charges per credit and limits you to their 150 pre-integrated providers. ZoomInfo locks you into $15,000+ annual contracts with stale quarterly-updated databases. Apollo gives you one data source — when they don't have a contact, you're stuck. Every tool forces you through the same painful loop: export CSV from CRM, upload to enrichment tool, wait, download, clean duplicates, re-import. Hours of work, every single week.
The Solution: Open Your Data to AI
Instead of building another proprietary enrichment engine, ListPlus gives AI direct access to your data through a secure API. The AI becomes your enrichment engine — with full internet access, real-time research capabilities, and zero per-lookup costs. Tell Claude: "Query all contacts with an empty Company field. Research each email domain. Fill in the company name, industry, and headquarters location." It does in minutes what used to take hours across multiple tools.
Three Steps. That's It.
Step 1: Create an API endpoint in ListPlus (one click). Step 2: Give the URL to any AI — Claude, ChatGPT, Gemini, or even your custom AI agent. Step 3: Tell it what to do in plain English. The AI discovers your list schema automatically, queries records that need work, researches using the full internet, and writes results back. Your CRM stays in sync through ListPlus's auto sync-back. The entire flow happens without you touching a CSV file.
Enterprise-Grade Security Controls
Giving AI access to your data sounds risky. It isn't — because ListPlus wraps every API endpoint in granular security controls. Hide sensitive columns entirely. Restrict which fields the AI can write to. Enable "fill-only-empty" mode so existing data is never overwritten. Set rate limits, row caps, and expiration dates. Every action is logged with timestamps and source IPs. You get the power of AI enrichment with the control of an enterprise security policy.
Connect Automation Tools for Continuous Enrichment
The API works with any automation platform — n8n, Zapier, Make, or custom scripts. Build a pipeline: new lead enters HubSpot → syncs to ListPlus → AI enriches missing fields → tags and qualifies the lead → syncs enriched data back to HubSpot. Run it daily, weekly, or on every new CRM record. Your data stays clean and complete without anyone thinking about it. No more manual enrichment sessions.
Why This Is Fundamentally Different
Traditional enrichment tools query static databases that decay 30% per year. AI enrichment queries the live internet. When Claude researches a contact, it visits the company website, reads recent press releases, checks LinkedIn profiles, and cross-references multiple sources — exactly what a human researcher would do, but in seconds instead of minutes. And as AI models improve (which happens every few months), your enrichment quality improves automatically. Zero engineering effort from you.
Frequently Asked Questions
How does AI enrichment through the API work?
You create an API endpoint in ListPlus (one click). Then give the URL to any AI — Claude, ChatGPT, or a custom agent. The AI makes a GET request to discover your list schema (columns, types, rules). Then it queries records that need enrichment, researches each one using its full capabilities (web search, knowledge base, reasoning), and writes results back via the API. ListPlus handles permissions, deduplication, and CRM sync automatically.
Is it safe to give AI access to my data?
Yes — ListPlus wraps every API endpoint in granular security controls. You can: hide sensitive columns entirely, restrict which fields the AI can write to, enable "fill-only-empty" mode (AI can never overwrite existing data), set rate limits and row caps, add expiration dates, require bearer token authentication, and review full execution logs. You control exactly what the AI can see and do.
How does this compare to Clay?
Clay is a walled garden — you can only use their built-in AI and their 150 pre-integrated providers, paying per credit ($0.10+). ListPlus opens the door to any AI model with full internet access. You pay your AI provider directly (typically $0.002-0.01 per query) instead of Clay's markup. Clay is also designed for "GTM engineers" with a steep learning curve. ListPlus works with plain English instructions to any AI you already use.
What AI models work with the API?
Any AI that can make HTTP requests. This includes: Claude (Anthropic), ChatGPT (OpenAI) via custom GPTs or API, Gemini (Google), Perplexity, and any custom AI agent. It also works with automation tools like n8n, Zapier, and Make — you can build workflows that combine AI enrichment with other data operations.
What can the AI do with my data?
The AI can: query records with filters (find empty fields, search by criteria), update records (fill in company names, industries, locations), add new records (create leads from research), tag records (classify as "qualified", "needs-review", etc.), organize into sublists, and count records for statistics. Each operation is controlled by per-endpoint permissions — you choose exactly which actions are allowed.
How much does it cost?
The API is included in all ListPlus plans. You pay your AI provider directly for token usage — typically $0.002-0.01 per enrichment query, which is 10-50x cheaper than traditional enrichment credits. There are no per-lookup fees, no credit packs, and no minimum commitments from ListPlus.
Can I automate enrichment to run continuously?
Yes. Connect the API to n8n, Zapier, or Make to build automated pipelines. Example: every day at 9am, query new leads from the last 24 hours, enrich empty fields via Claude, tag qualified leads, and sync everything back to HubSpot. The pipeline runs without human intervention. Your CRM data stays complete and current automatically.
