Company Funding

Retrieve a company’s funding history - rounds with dates, investors, amounts, and valuations, plus acquisition detail when applicable - aggregated from verified sources. Supply at least one of company_name or company_domain. The request is queued asynchronously and returns a request_id; poll the status endpoint or supply a callback_url. The completed result includes a funding_rounds array (most recent first) and an optional acquired object. Rounds may carry an amount_approximate flag when the figure is an estimate, and each investor in funded_by may be marked lead_investor. A credit is charged only when funding data is found.

Manual credentials take precedence over your account key.

Overview

Retrieve verified funding-round and acquisition history for a company.

Parameters

company_name string optional
Company name to look up, e.g. “Stripe”, “OpenAI”. Required unless company_domain is supplied. Max 255 chars.
company_domain string optional
Company domain to look up, e.g. “stripe.com”. Required unless company_name is supplied. Max 255 chars.
callback_url string optional
http(s) URL on an allowed host that receives the completed payload automatically.

Polling for the result

This endpoint is asynchronous. A successful submit returns a request_id while the job runs in the background. Poll the same path with a GET request - same authentication headers - passing the request_id as a query parameter:

Each poll returns the job's current status; once it is completed the payload carries the result shown under Responses. Polling an unknown or expired request_id returns 404 request_not_found.

Status Meaning
queued · processing · pending The job is still running - keep polling.
completed The job finished; the payload carries the result and completed: true.
failed Terminal - the job could not complete; the error field explains why.

Poll every few seconds at first, backing off for long-running jobs. Polling is free - status checks never burn credits.

Prefer push delivery?
Supply the optional callback_url parameter and the completed payload is POSTed to your endpoint when the job finishes - no polling required. Delivery is retried up to 5 times with exponential backoff (1s, 5s, 15s, 1m, 5m) and a 30-second timeout per attempt; respond with a 2xx status to acknowledge receipt.

Credit usage

Credits are charged based on the matched configuration. The listed cost is the per-result unit price.

Feature Credits Notes
Funding Lookup - Charged once when funding data is retrieved
No data 0 No funding found never burns credits
Heads up
A positive credit balance is required before each request. Empty results do not burn credits.
