API reference / People reads

Search lead companies (live)

Written and maintained by The ProspectAPIs team

POST/v1/leads/companies/search

POST /v1/leads/companies/search is the ProspectAPIs operation searchLeadCompanies, in the People reads group of the REST API. Search companies as sales accounts by keywords and account filters, read fresh. Each result carries name, company_id, page_url, industry, size_band, employee_count, location and description. Returns the first 2,500 results per query; page with start. $0.0035 per result returned; an empty search is free. Not available yet: the call answers 503 temporarily_unavailable and nothing is charged until GET /pricing reports lead_search.available. Cost: Not available yet. Send your API key as a Bearer token in the Authorization header.

The quickstart shows this call in context, next to the first requests most integrations make.

Parameters

Request body

JSON. Give keywords or at least one filter.

{}

Responses

Every error answers with the same JSON body, an error string and sometimes a code; the errors page lists each status and when it happens. A per-key 429 carries Retry-After; see rate limits.

200 response fields

The matching companies and the page envelope, read fresh. The body is a PeopleReadResult.

Code samples

Each sample sends the same request. Set PROSPECTAPIS_KEY in your environment first. Values come from the spec's examples; replace them with your own.

curl -X POST https://api.prospectapis.com/v1/leads/companies/search \
  -H "Authorization: Bearer $PROSPECTAPIS_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

const res = await fetch("https://api.prospectapis.com/v1/leads/companies/search", {
  method: "POST",
  headers: { Authorization: `Bearer ${process.env.PROSPECTAPIS_KEY}`, "Content-Type": "application/json" },
  body: JSON.stringify({}),
});
if (!res.ok) throw new Error(`${res.status}: ${(await res.json().catch(() => ({}))).error ?? res.statusText}`);
const data = await res.json();
console.log(data);

import os, requests

res = requests.post(
    "https://api.prospectapis.com/v1/leads/companies/search",
    headers={"Authorization": f"Bearer {os.environ['PROSPECTAPIS_KEY']}"},
    json={},
    timeout=30,
)
res.raise_for_status()
data = res.json()
print(data)

Billing

Billing reserves before it serves: the call holds what it may cost, serves at most what that hold covers, and refunds the rest when the response closes. Any non-2xx answer refunds the whole hold, so a failed call costs nothing. The response reports your balance in X-Credits-Remaining.
