Best BYOK Enrichment Tool for n8n Users (2026)

LeadModule is a waterfall enrichment platform that lets n8n users call a single REST API endpoint to find verified emails and phone numbers across 8+ data providers — with full BYOK support on the free tier.

If you're building outbound automation in n8n, you need enrichment. But most enrichment tools are designed for humans clicking in a UI, not for automation engineers calling APIs. BYOK support is often locked behind high-tier plans, and async provider handling (Dropcontact, FullEnrich) usually requires manual webhook plumbing on your end.

This page covers what to look for in an enrichment tool for n8n, how BYOK changes the cost model, and why LeadModule fits cleanly into automation workflows.

TL;DR

• Best overall for n8n: LeadModule — clean REST API, BYOK on free tier, handles async providers internally
• BYOK access on Clay: Requires $134/mo Explorer plan
• BYOK on FullEnrich / BetterContact: Not supported — you pay their bundled pricing
• Find rates: ~95% with waterfall vs ~60% single-provider
• n8n integration: HTTP Request node → POST /api/v1/enrich → done

Why BYOK Matters for Automation Builders

Standard enrichment tools sell credits at a markup. You pay $0.05–$0.15 per successful enrichment, and they pocket the difference between their cost and yours.

BYOK flips this. You bring your own API keys from Prospeo, Hunter, Findymail, or Dropcontact. The enrichment platform uses those keys for the actual lookups. You pay provider rates directly — often 40–60% less than bundled credit pricing — and the platform charges only for orchestration (or nothing, if it's on the free tier).

For n8n users running automation at volume — scraping LinkedIn, enriching prospect lists, building outbound pipelines — that cost difference adds up fast.

What to Look For in an n8n Enrichment Tool

1. Clean REST API

An enrichment tool built for automation needs a simple, predictable REST API: send a name + company (or LinkedIn URL), get back an email + phone. No polling loops, no spreadsheet UI to navigate, no webhook setup on your end.

LeadModule's API takes this approach:

POST /api/v1/enrich
Authorization: Bearer <api_key>

{
  "first_name": "Jane",
  "last_name": "Smith",
  "company": "Acme Corp"
}

Response includes the verified email, provider used, and enrichment confidence. No additional steps.

2. BYOK on the Plan You're Actually On

BYOK access locked behind a $134/mo plan means you're paying for the platform to hold your keys. For solo operators and small teams, that's a meaningful fixed cost before you've run a single enrichment.

LeadModule includes BYOK on the free tier. You connect your provider API keys in the settings panel, configure the waterfall order, and use the same /api/v1/enrich endpoint. Your keys are used for the lookups; you pay provider rates.

3. Async Provider Handling

Several of the best-performing enrichment providers — Dropcontact, BetterContact, FullEnrich, Wiza — are async. They don't return results immediately. Instead, they process the request and call back via webhook when ready, which can take 5–30 seconds.

Handling this yourself in n8n means: POST to provider → wait → receive webhook → match to original record → continue workflow. That's extra nodes, complexity, and failure surface.

LeadModule handles async providers internally. You make one API call. LeadModule polls the async provider in the background and returns the result once it's ready. From n8n, it's a single HTTP Request node.

4. Waterfall Logic (Not Just One Provider)

Single-provider enrichment tools find data in roughly 60% of cases. A waterfall — where a miss on Provider A triggers a lookup on Provider B, then C — reaches approximately 95%.

For outbound automation, this matters. A list of 1,000 contacts with a 60% find rate gives you 600 enriched leads. The same list through a waterfall gives you ~950. That's 350 more prospects from the same source.

How LeadModule Fits into an n8n Workflow

A typical enrichment workflow in n8n looks like this:

1. Trigger: New row in a Google Sheet (prospect list), Airtable record, or HTTP webhook
2. Enrich: HTTP Request node → POST /api/v1/enrich to LeadModule
3. Branch: If email is present → continue to outreach step; if null → log for manual review
4. Push: Write the enriched record to your CRM, Instantly, Smartlead, or wherever it's going

Because LeadModule returns a synchronous response, there's no waiting node or webhook receiver required. The HTTP Request node in n8n handles the call inline.

If you're on BYOK, you connect Prospeo, Hunter, and Findymail to LeadModule once. The waterfall config determines the provider order. After that, every enrichment request follows the same path — your n8n workflow doesn't change when you add or swap providers.

How BYOK Enrichment Pricing Compares

FullEnrich and BetterContact do not offer BYOK. You pay their credit rates, which include their margin. For automation workflows at scale, that adds up.

Clay offers BYOK but requires the $134/mo Explorer plan to access it. For teams already using Clay for GTM workflows, that plan may already be justified. For automation builders who just need enrichment, paying $134/mo to access their own API keys is a high overhead cost.

Clay vs LeadModule for n8n Enrichment

Use Clay if:

• You need enrichment plus AI-powered data transformation, CRM sync, LinkedIn scraping, or complex GTM workflows
• You already pay for Explorer+ and want to consolidate tooling
• Your workflow lives inside Clay's spreadsheet paradigm

Use LeadModule if:

• You're building automation in n8n, Make, Zapier, or custom code
• You want BYOK without a $134/mo plan
• You need a clean REST API that returns results synchronously
• You want async providers (Dropcontact, FullEnrich) handled without webhook plumbing

Many teams use both: Clay for orchestration and AI columns, LeadModule called via HTTP Request for the enrichment step. That keeps Clay's workflow power while keeping enrichment costs under control.

Setting Up LeadModule in n8n

1. Create an account at leadmodule.ai — free tier has BYOK
2. Connect your provider keys in Settings → Providers
3. Configure a waterfall — set provider order and rules
4. Get your API key from Settings → API
5. In n8n: Add an HTTP Request node, set method to POST, URL to https://leadmodule.ai/api/v1/enrich, add Authorization: Bearer <your_key> header, and pass the lead fields in the request body
6. Parse the response — the email and phone fields are at the top level of the response JSON

Total setup time: under 10 minutes for a working enrichment step.

FAQ

What is BYOK enrichment? BYOK (Bring Your Own Keys) means you connect your own API keys from data providers to an enrichment platform. You pay provider rates directly instead of a platform credit markup.

Can I use LeadModule with n8n? Yes. Use an HTTP Request node with a POST to /api/v1/enrich with your LeadModule API key in the Authorization header.

Is BYOK enrichment free on LeadModule? The free tier includes BYOK — you pay provider rates directly, with no LeadModule credit charge. The $49/mo Starter plan adds 250 managed credits for providers where you don't have your own keys.

What providers does LeadModule support? Prospeo, Findymail, LeadMagic, Hunter (sync); Dropcontact, BetterContact, FullEnrich, Wiza (async). 8+ total.

Does Clay support BYOK for n8n users? Yes, but only on the Explorer plan ($134/mo and above). Clay is also primarily a spreadsheet UI — it is not designed for clean REST API calls from automation tools.

What find rates should I expect? Single-provider enrichment runs around 60%. A waterfall across multiple providers reaches approximately 95%.

Does LeadModule handle async providers like Dropcontact in n8n? Yes — async providers are handled internally. Your n8n HTTP Request node makes one call and gets one response. No webhook receiver required.
