The 3 Enrichment APIs
Every Clay User
Is Wrong About.

Every Clay table I've ever seen defaults to the same three vendors: ZoomInfo, Apollo, Hunter. The Clay community has decided these are "the stack." They're not. All three are wrong for production workflows. Here's why, and what to use instead.

Why Clay defaults to these three

Clay's growth playbook in 2023-2024 was tutorials. Sam Kuehnle, Eric Nowoslawski, and the broader Clay influencer set published hundreds of "watch me build a Clay table" videos. Almost all of them used ZoomInfo + Apollo + Hunter because those three had the easiest UI integrations.

The community learned by copy. Templates spread. The tutorials never said "use these three vendors forever." They said "here's the cheapest way to build your first table." Two years later, that's the default for everything.

The default is wrong for anything that runs every day at scale. Here's the breakdown.

ZoomInfo: enterprise contract, API afterthought

ZoomInfo has the deepest data set of the three. They also have the worst API model for builders.

• 12-month minimum contracts. Their API isn't sold per-call. You commit to ~$30,000 for the year, then burn through your "credits" by making calls. If you finish early, you call your rep. If you don't use them, they roll over for 60 days then disappear.
• Mandatory sales calls. You can't sign up via curl. There is no developer self-serve. A rep schedules a discovery call, a security review, an MSA negotiation, a kickoff. Three weeks minimum from "I want to try this" to "I have a key."
• Per-seat licensing. The API is in their "Enterprise+" tier. If you add a second developer, you renegotiate the contract.
• No MCP server. No native agent install. Their tooling assumes humans clicking buttons in a SaaS UI.

For a Clay user running a 25-row test query? Fine. For an AI agent making 500 calls a day? You're paying $30k upfront before you write line one.

Apollo: UI-first, API as crutch

Apollo started as a SaaS for sales reps. The API was bolted on later to satisfy enterprise customers. It shows.

• API requires UI account. You can't have a pure-API account. You sign up as a "user" first, then unlock API access from inside the UI. Seat fees apply.
• The API surface is shallow. They sell their value through workflows in their UI. The endpoints expose primitives but not the higher-order combinations (no buying-committee endpoint, no funding-radar combo). To replicate Apollo's UI workflows via API, you write the orchestration yourself.
• Per-call rate limits are tight. 100 requests/minute on most plans. Try running an agent that processes 500 leads at once. You're queueing.
• Email accuracy depends on the source. Their "verified" emails include unverified sources marked as verified. Test sample before you ship.

Apollo is the right call if your team includes humans who want to run searches in a UI and occasionally export. It's the wrong call if your team is "Claude + a cron job."

Hunter: email-only, no signals, no SMB

Hunter is honest about what it does. It finds verified business emails. That's the whole product.

• Email-only. No mobile phones. No decision makers. No buying committees. No signals. If your workflow needs anything beyond email, you're stitching Hunter + another vendor.
• Cheap per-email but expensive per-lead. $0.04 per verified email. But you typically need email + phone + role + recent activity. Hunter handles 1 of 4. You're paying for the other 3 somewhere else.
• No real-time signals. Hunter can't tell you a company just got funded. It can't tell you a person just changed jobs. It's a static lookup.
• No SMB / local-business data. Hunter indexes companies with websites and corporate email infrastructure. Local plumbers, med spas, HVAC companies are off the grid for them.

Hunter is a good component. It is a bad stack. The Clay community treats it as a stack.

What you actually need (for production)

A production enrichment workflow has six requirements. Most Clay setups satisfy 2-3 of them. Here's the full list:

AgentEnrich ships all six in one bundle. That's the pitch. Not "we're cheaper" (we are, but cheaper isn't the wedge). The wedge is "one bill instead of four."

Side-by-side cost: same workflow, different stacks

Take a real workflow: 1,000 leads/month, each fully enriched with email + phone + decision-maker + funding signal.

The hard part isn't picking a vendor. The hard part is admitting that the "Clay stack" is three separate vendor contracts dressed up as one product.

Migrating from the Clay defaults

You don't have to rip Clay out. Use both. Clay for visual one-off campaigns. AgentEnrich for production workflows that run every day.

Step 1: Replace ZoomInfo column with AgentEnrich

In Clay, add an HTTP column. POST to api.agentenrich.com/v1/enrich with the bearer token. Map the row's LinkedIn URL to the request body:

URL: https://api.agentenrich.com/v1/enrich
Method: POST
Headers:
  Authorization: Bearer ae_live_xxxxx
  Content-Type: application/json
Body:
  { "kind": "linkedin", "linkedinUrl": {{ "LinkedIn URL" }} }
Cost: 1 credit per row

That's the entire ZoomInfo replacement. Same Clay table. Same row outputs. 1/30th the cost.

Step 2: Replace 7-cell waterfalls with combo endpoints

Most "find me the decision maker" Clay waterfalls look like this:

1. Find company by domain (Clearbit column)
2. Find decision-maker candidates by title (Apollo column)
3. Filter by seniority (formula)
4. Verify email (Hunter column)
5. Find phone (Lusha column)
6. Get LinkedIn URL (Apollo column #2)
7. Get recent activity (Champify column)

Seven cells per row. Seven vendors. Seven failure points.

Replace with one HTTP column hitting /v1/find-decision-maker followed by /v1/prospect-package. Two calls. Same outputs. 90% lower cost.

Step 3: Replace the Crunchbase column with funding-radar

If you're filtering by "funded in the last 30 days," use /v1/funding-radar. It returns funded companies plus the decision maker at each in one shot, with freshly-aggregated data (sub-60-minute latency on funding announcements). No Crunchbase license needed.

Step 4: Add what Clay can't do

Once you're in, use what Clay defaults don't cover:

• /v1/local-business-owners for B2SMB targeting (plumbers, med spas, HVAC, etc.)
• /v1/congrats-trigger for actual LinkedIn announcement-post text (unique to us, 5x reply rates)
• /v1/champion-just-moved for customer-power-user tracking
• /v1/multi-source-phone for waterfalled phone enrichment with higher hit rates

These don't exist in the Clay defaults. They're the differentiator.

When to keep using Clay

Clay is genuinely the best tool for some jobs. Don't rip it out where it shines:

• One-off campaign exploration. When a marketer wants to "test 3 ICP filters" by Friday, Clay's UI is faster than any code editor.
• Visual debugging. Seeing 500 rows update one cell at a time is irreplaceable when you're learning a new data shape.
• Cross-functional handoff. Sales ops likes spreadsheets. Clay is a programmable spreadsheet. Use it where the receiver is non-technical.

The rule of thumb: if the workflow runs more than once a week, move it to an API. If it's a one-time pull, do it in Clay.

FAQ

Is AgentEnrich a Clay alternative?

No. AgentEnrich is the data layer underneath Clay, not a Clay replacement. Use both. Clay for visual one-offs. AgentEnrich for production. Drop us in Clay as an HTTP column for the production columns. See our Clay users page for the integration recipes.

How much do Clay teams actually pay per month?

Clay starts at $149/mo per seat. Most production Clay teams spend $1,500 to $3,000/mo once you add 3-5 seats and credit packs. A single decision-maker waterfall chains 7-14 enrichment calls per row, each billed by the vendor. Costs compound fast.

What about Lusha, Cognism, RocketReach?

Credible single-source providers, each with their own strengths. Lusha is strong on phones. Cognism is EU-focused. RocketReach has historical depth. None ship combo endpoints, real-time signals, SMB owner data, or an MCP server in one bundle. We aggregate where they're strong and add what they're missing.

What's the catch on "$97/mo for 130k credits"?

No catch. It's our Pro tier founding rate, locked for life on the first 1,000 accounts. Each lookup costs 1-30 credits depending on type (enrich 1 cr, email 2 cr, phone 12 cr, premium bundle 25 cr). Mix freely. No top-ups. No surcharges. Hit your monthly pool and you can upgrade mid-month (prorated) or wait for reset. See /pricing.

Can I run the AgentEnrich MCP server inside Clay?

The MCP server is an LLM-tool surface. Clay isn't an LLM-native runtime. So no, not directly. The right Clay integration is the HTTP column. Use MCP when your runtime is Claude Desktop, Cursor, Windsurf, or a custom agent. See our AI SDR tutorial for the MCP usage path.

Will Clay sue me for migrating?

No. You're a customer. Move your workflows wherever they belong. Clay's product team would probably tell you the same thing. Their thesis is "build the best visual tool"; they don't need you to use Clay for the parts where an API is better.
