ZoomInfo
Depends
Confidence: High
Buy only if you run a large outbound sales org that can absorb ~$30K-$60K/year and negotiate hard.
| Compare | Openapi | ZoomInfo |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Fintech and KYC teams needing certified company data | Enterprise outbound sales teams |
| Who it's not for | Anyone who actually wanted OpenAI or the OpenAPI spec | Small teams . five-figure annual commitment |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁴ | Mature security program (bug bounty, published overview); one alleged 185M-record database sale remains unconfirmed.14 |
| Support quality | No user evidence found | No direct support evidence found |
| Public sentiment | Independent user feedback is thin; one Reddit thread questioned trustworthiness and ScamAdviser rates the site legit.⁵ | Sentiment splits: the data depth is praised, while price, auto-renewal, and navigation draw frequent criticism across Reddit, G2, and Trustpilot.⁸ |
| Biggest gotcha | Wallet-based pay-per-call billing; heavy usage without subscriptions roughly doubles costs² | Auto-renewal and multi-year locks are the top contract trap |
