Request

Every LinkFinder lookup goes to the same endpoint, POST https://api.linkfinderai.com. The type field selects the lookup; input_data carries the input as a plain string.

Field		Value for this lookup
`type`	required	`company_name_to_phone`
`input_data`	required	Company Name, e.g. `Tesla`

Authenticate with your API key as a Bearer token. Keep it server-side; never ship it in a browser or a mobile app.

Response

A successful call returns {"status": "success", "result": ...}. For this lookup the result carries the phone. When nothing is found, result is null; the call is still charged, so cache your inputs and do not retry a null.

Most calls return the result inline with 200. When a lookup takes longer, you get 202 with a job_id and a poll_url instead; poll GET /status/{job_id} until status is done.

Credits and errors

1 credit per lookup. 401 means the key is missing or wrong, 402 means the account is out of credits, 422 means the type or the input is malformed, and 429 means you are being rate limited; back off and retry.

This returns the company's published main line, not a person's mobile. For a direct dial to a specific employee, run their LinkedIn profile through the phone number finder instead.

Use it from an automation tool

The same request works from an HTTP node: see n8n, or the integrations page for Make, Zapier, Clay and the MCP server. Bulk without code: upload a CSV.
