Credit Usage by Endpoint

​
Person API — with contacts

Each successful person lookup consumes standard SignalHire credits. These are the same credits used across the SignalHire website, browser extension and api — the balance is shared between all three.

​
Person API — without contacts

Retrieving profiles without contact details requires a separate credit type, independent of the standard balance. To purchase without-contacts credits, contact support@signalhire.com.

​
Search API

Search requests are not billed per credit — instead, they count against a daily search quota. This quota is shared between the SignalHire website and the API, so searches made in either place consume from the same daily limit.
  • The quota covers both the number of search queries and the total number of profiles returned — both are tracked separately against daily limits
  • The quota resets daily
  • The quota varies by plan and is set individually — trial accounts have a significantly lower limit than paid accounts
  • When the daily quota is exhausted, the API returns HTTP 402

Tracking Usage

To check remaining credits at any time, use the Get Remaining Credits endpoint or check the X-Credits-Left header included in every API response.

​
Company API

The Company API uses two independent credit types, both separate from Person API credits:
  • Company data credits — consumed by the /company/info endpoint. Each successful call consumes one credit.
  • Profile credits — consumed by /company/getProfiles when fetching employee profiles.
The /company/findById and /company/getCount endpoints do not consume any credits. The Company API is available on request — contact support@signalhire.com to enable access and purchase the required credits.
