LeadOcean + Clay: personalize emails to companies by ICP

You get a Clay table where each target company carries its industry, headcount band and detected tech, plus a fit flag and a one-line opener that names the match. Clay's own template builds the opener from the company's one-liner, its typical ICP and customers named on its website (Clay template, September 2026). This recipe adds a structured layer underneath: firmographic fields from one LeadOcean call, so the opener rests on data you can filter and score.

Use it when you already have a list of domains. If you need the list first, size it free with GET /v1/companies/count, then search.

How it works

1. Get a free key. Sign up at app.leadocean.io/register. No card, 1,000 records.
2. Load your target domains into Clay. One row per company, one Domain column.
3. Add the HTTP API column. POST each domain to https://api.leadocean.io/v1/companies/enrich. Clay lists the HTTP API column on Growth and Enterprise (Clay pricing, September 2026).
4. Skip rows already filled. Clay supports an "only run if" formula on this column (Clay docs, October 2026).
5. Flag ICP fit. Add a formula column that compares industry, headcount band and tech to your ICP.
6. Draft the opener. Add an AI column that reads the fit flag and the company fields.
7. Review, then send from your own inbox or sequencer. LeadOcean has no sequencer.

Configuration

/Domain is Clay's reference to the domain column. Save x-api-key once as an HTTP API (Headers) account and select it (Clay docs, October 2026).

Method:   POST
URL:      https://api.leadocean.io/v1/companies/enrich
Header account: LeadOcean (x-api-key)
Body:     { "domain": "/Domain" }
Field paths to return:
          data.company_data.company_name
          data.company_data.company_industries
          data.company_data.company_employees
          data.company_detected_technologies
          data.company_data.company_description

Test one domain in a terminal first.

curl -X POST "https://api.leadocean.io/v1/companies/enrich" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "content-type: application/json" \
  -d '{"domain":"acme.com"}'

A fit formula can be plain. Write your ICP once and let the column answer yes or no.

fit = industry in ["Computer Software", "Information Technology and Services"]
  AND number_of_employees_code in ["51-200", "201-500"]
  AND "HubSpot" in detected_technologies

Industry values are exact strings; check them with GET /v1/enums. Technology names match technology_product.name as written.

Field mapping

Cost at 10,000 rows

LeadOcean is $0 for the first 1,000 records. For 10,000 domains use Solo at $97 a month (10k enrichments every 5 hours) or Agency at $497 a month. There is no per-record price.

A hit counts one record. A domain we hold nothing for returns a 404 and costs nothing.

Clay's HTTP API column starts on Growth at $495 a month billed monthly, or $446 billed yearly. Each call uses one Action, and Growth includes 40,000 Actions a month (Clay pricing, September 2026). Ten thousand domains use a quarter of that. The AI column adds one Action per run, plus Data Credits unless you connect your own AI key (Clay docs, October 2026). Clay publishes no fixed credit price per AI row.
