ipto vs AbstractAPI
AbstractAPI's free tier is a genuine standout on one axis — it includes VPN, proxy, Tor, hosting, and abuse detection with a reputation score, which most competitors gate behind a paid plan. The tradeoff is volume and pace: 1,000 requests/month at 1 request/second, the tightest free rate limit in this comparison. Their pricing also has a real quirk worth knowing before you upgrade: the cheapest paid tier (Starter, $17/month) actually excludes company data, security, and domains — features the free tier already includes.
| Feature | ipto | AbstractAPI |
|---|---|---|
| Free tier security data | Yes | Yes — genuinely good here |
| Free tier rate limit | None for normal use | 1 request/second |
| Free tier volume | Unlimited | 1,000/month |
| Paid tier consistency | n/a (one free tier) | Starter tier excludes security/company/domains that the free tier includes |
| Connection-type detail (DSL/cellular/satellite) | No | Yes |
| Platform integrations (Salesforce, Zapier, etc.) | No | 20+ native integrations |
| Compliance certifications published | No | SOC 2 Type II, GDPR |
| User-Agent / device parsing | Yes — GET /v1/ua, browser/OS/device/bot detection, also on the account dashboard | No dedicated UA-parsing product found in their API suite (geo, email, phone, exchange rates) |
When AbstractAPI might fit better
- You need native integrations with Salesforce, HubSpot, Zapier, or similar platforms out of the box.
- Published SOC 2 Type II / GDPR compliance documentation is a procurement requirement.
When ipto fits better
- A 1-request-per-second ceiling is too slow for your use case — ipto has no comparable throttle on free use.
- You want consistent feature access as you scale, instead of checking whether your specific paid tier still includes what the free tier had.
FAQ
Does AbstractAPI's free tier really include security data?
Yes — unusually for this comparison set, their free tier includes VPN/proxy/Tor/hosting detection and a reputation score. The catch is the 1,000/month, 1-request/second ceiling.
Why would a paid tier have fewer features than free?
AbstractAPI's $17/month Starter tier is positioned as a pure volume upgrade (5,000/month) and explicitly excludes company data, security, and domains — you need their $37+ tiers to keep what the free plan already gave you, alongside more volume.
