Use case · n8n, Make & Zapier builders

Enriched local leads as a step in your n8n, Make or Zapier flow

People who build automations for themselves or clients and need fresh local business data flowing into a CRM or sequence.

The job

Trigger a search from a form, schedule or sheet row, then send enriched businesses straight into a CRM, Google Sheet or cold email tool.

How it is usually done today

Running a scraper by hand, downloading a CSV, and uploading it to the next tool.
Chaining a Maps scraper module, an email finder module and a verifier module.
Paying per-operation for every lookup step in the scenario.

Why that hurts

Manual export/import breaks the "automation" part.
Every extra vendor in the chain adds another place for a run to fail.
Unverified emails go straight into sequences and hurt deliverability.

How LeadMerlin does it

1

Start a job

HTTP POST /v2/searches with a keyword and 1–5 location codes. Store the returned job_id.
2

Wait and poll

Wait, then GET /v2/jobs/:id. Repeat until status is "completed".
3

Fetch results

GET /v2/jobs/:id/results and follow next_cursor while has_more is true.
4

Route the data

Filter on email status = verified or phone_type = mobile, then send to your CRM or sequencer.

The HTTP calls your workflow makes

curl -X POST "https://api.leadmerlin.com/api/v2/searches" \
  -H "x-api-key: $LEADMERLIN_API_KEY" \
  -H "content-type: application/json" \
  -d '{"keyword":"roofing contractor","location_codes":[1026201],"strictness":"moderate"}'

curl "https://api.leadmerlin.com/api/v2/jobs/$JOB_ID" \
  -H "x-api-key: $LEADMERLIN_API_KEY"

curl "https://api.leadmerlin.com/api/v2/jobs/$JOB_ID/results?limit=200" \
  -H "x-api-key: $LEADMERLIN_API_KEY"

Location codes in these examples are placeholders — always look yours up with GET /v2/locations first.

What comes back

Most useful for this job:

Email status labels (verified / catch-all / invalid / unverified) you can filter on before sending.
Phone line type so SMS steps only go to mobile numbers.
Flat top-level fields (owner, email, phone, phone_type) that map cleanly to CRM columns.

Every field on an enriched lead

Google Business Profile basics: name, category, address, rating, review count, claimed status, GBP URL, CID
Owner name and a short business summary, extracted from the website by an LLM when the site states them
Every email found, labelled verified / catch-all / invalid / unverified, with role-based and free-provider flags
Phones from the listing and website; the main number (Google listing first) gets line type (mobile, landline, VoIP, toll-free) and carrier, up to your plan's monthly line-type allowance
Tech stack: CMS, CDN, server, chat widget, online booking tool, online ordering / POS storefront, review widgets, analytics, frameworks, ad pixels
Social profiles, services, service areas, year established when stated
Raw text, title and meta description of up to 5 crawled pages per site

Limits and honest caveats

LeadMerlin is used through generic HTTP modules. There is no official n8n node, Make app or Zapier app yet.
Because jobs are asynchronous, your flow needs a wait/poll step.
Zapier has no native loop over pages; large result sets are easier in n8n or Make.

Phone line-type lookups have a monthly allowance: 100 on the free start, 1,000 Starter, 2,000 Pro, 4,000 Agency. Numbers looked up before are free. Past the allowance, phones still come back without a line type.

FAQ

Which platform is easiest?

n8n and Make both handle polling loops and pagination well. Zapier works for smaller result sets with a Delay step.

Can I enrich leads I already have?

Yes. POST up to 100 domains per request to /v2/enrichments and use the same poll and results flow.

How do I authenticate?

Send your key in the x-api-key header. In n8n use Header Auth credentials; in Make and Zapier add it as a request header.
