Get a company's funding rounds

Written and maintained by The ProspectAPIs team

GET/v1/companies/:domain/funding

GET /v1/companies/:domain/funding is the ProspectAPIs operation getCompanyFunding, in the Companies group of the REST API. The funding rounds for one company domain, newest first: the same records as GET /v1/funding filtered to this domain. Costs one record per record returned; a company with no rounds is free. Coverage: funding rounds are complete from 2026-10-01, partial from 2026-09-22 to 2026-09-30, and only a few earlier rounds are held, so a company whose last round was before that returns none, and an empty answer carries a coverage object saying so. Cost: $0.009 per record returned, a company with no rounds is free. Send your API key as a Bearer token in the Authorization header.

How this fits with the rest of the companies API, with worked examples, is in the company profiles guide.

Parameters

An unknown query parameter is refused with a 400 rather than ignored, so a typo never widens a search you pay for.

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

A page of funding rounds for the domain. The body is a FundingList.

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 -G https://api.prospectapis.com/v1/companies/acme.com/funding \
  -H "Authorization: Bearer $PROSPECTAPIS_KEY" \
  --data-urlencode "since=2026-10-01" \
  --data-urlencode "round=seed,series_a" \
  --data-urlencode "limit=10"

const params = new URLSearchParams({ since: "2026-10-01", round: "seed,series_a", limit: "10" });
const res = await fetch(`https://api.prospectapis.com/v1/companies/acme.com/funding?${params}`, {
  headers: { Authorization: `Bearer ${process.env.PROSPECTAPIS_KEY}` },
});
if (!res.ok) throw new Error(`${res.status}: ${(await res.json().catch(() => ({}))).error ?? res.statusText}`);
const data = await res.json();
console.log(data);

import os, requests

res = requests.get(
    "https://api.prospectapis.com/v1/companies/acme.com/funding",
    headers={"Authorization": f"Bearer {os.environ['PROSPECTAPIS_KEY']}"},
    params={"since": "2026-10-01", "round": "seed,series_a", "limit": 10},
    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.
