Key points

  • Choose the operation by the identifier you have.
  • Wait for the completed lookup before using its fields.
  • Compare credit use on the same inputs.

Choose between RocketReach and Dievio by what you know about the person. A name and employer can call for an identity lookup. An existing public LinkedIn profile URL gives you a stronger input. A role at an account calls for discovering candidates first.

Compare the same input in both tools

Role and companyUse People Search to identify candidates, then look up the person whose contact fields you need.Enter company domains and title filters. Use Preview to count the audience before requesting contact rows.

Name and employer without a URLThe documented SDK includes a lookup with name and current employer.Use filtered search to find a candidate and review their identity. The LinkedIn Lookup operation requires a supported URL.
Spreadsheet of public profile URLsCheck which batch route your account supports. The SDK shows individual URL lookups. Its sample CSV script takes name and company columns.Upload the CSV, select the public profile URL column and keep source IDs for the report.

Follow a lookup through its final state

In RocketReach’s sandbox, candidate search and contact retrieval were separate. A person lookup could return a progress state before completion. If your workflow makes asynchronous requests, wait for the completed result before writing the contact into a CRM. Treat sandbox records as examples of the response contract. They cannot measure current company coverage or contact accuracy.

For a Dievio CSV lookup, distinguish rows that matched, rows checked without results and rows that were never checked. A match can still have an empty work email or phone. For the input format and report columns, see the LinkedIn Lookup guide.

Measure the cost of the field you need

Run one known URL in both tools. Then use a separate fixed batch and keep the same requested fields. Write down the plan, credit balance before and after, completed lookups and accepted rows. Compare work-email retrieval separately from phone retrieval. Check the credit model for the RocketReach endpoint you use. Dievio’s API and dashboard have separate balances.
