- –Data refreshes roughly monthly, so job titles and employers can be weeks-to-months stale
- –Heavy reliance on LinkedIn means non-LinkedIn people are under-represented and some self-reported titles leak through
- –Verified emails and direct-dial phones often require extra Person Identify calls at higher per-match cost
- +Published per-request and per-tool prices
- +people_search tool with documented parameters
- +Python and TypeScript SDKs with async clients
- –Sonar chat completions is being retired in favour of the Agent API

- –No free API credits found
