Strengths and weaknesses
- +Large database (275M+ contacts, 73M+ companies) with strong US coverage (~80–88% match accuracy)
- +Aggressive pricing that undercuts ZoomInfo/Lusha-class incumbents for comparable breadth
- +Bulk enrichment endpoints (up to 10 people or companies per call) reduce call volume
- –Data accuracy drops sharply outside the US (~60–73% in EU/APAC/LATAM); stale titles common
- –Phone numbers cost 8 credits each yet user-reported direct-dial accuracy is only ~50–70%
- –Credits expire every billing cycle with no rollover and no refund on unused balance
- +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
- –people_search is model-mediated, not a filterable candidate index
- –No free API credits found
