The prompt
Find engineering managers at marketing and advertising agencies in the United States.
1. Call leadocean_list_enum_values for industry and pick the marketing
and advertising agency values.
2. Call leadocean_count_leads with title Engineering Manager,
jobLevel Manager, those industries and country US.
3. Tell me the count and the filters you used.
4. Do not call leadocean_search_leads until I say go.What it resolves to
| Filter | Value |
|---|---|
| title | Engineering Manager |
| jobLevel | Manager |
| industry | Advertising Services, Marketing Services, Marketing and Advertising |
| country | US |
"Agency" is not an industry value, so the prompt maps it to the three marketing and advertising strings. Enum values are exact strings, which is why step 1 looks them up.
How many match
496 mailable people matched on 2 October 2026. Filters: title Engineering Manager, jobLevel Manager, industry Advertising Services, Marketing Services or Marketing and Advertising, country US.
Mailable means verified, catch_all_valid or catch_all, the count_leads default. The count is free. The facets show 391 sit under Advertising Services, 101 under Marketing Services and 4 under Marketing and Advertising. By size, 133 are at companies with 1001-5000 employees and only 29 at 1-10, so set employeeRange before you write copy.
What you get back
Search rows carry the fields below, plus name, email status and company domain. These are placeholder values, not real records.
| Title | Company size | Industry | Country |
|---|---|---|---|
| Engineering Manager | 1001-5000 | Advertising Services | US |
| Engineering Manager | 51-200 | Marketing Services | US |
| Engineering Manager | 11-50 | Marketing and Advertising | US |
Variations
- Add "only employeeRange 201-500 and 501-1000" to skip small shops with no engineering team.
- Swap the title line for "Director of Engineering, jobLevel Director" to reach the layer above.
- Change country to GB and ask Claude to count again before searching.
