Transparency Is Not a Feature. It's Our Foundation.

Most email verification APIs are black boxes. You send an email, get a score, and trust that something happened. We don't think that's good enough.

Per-Phase Performance Timing

Every validation response includes exact millisecond timing for syntax, domain check, DNS, SMTP, and catch-all detection. See exactly where time was spent — no guessing.

Real SMTP Verification — Even on Free

Most free tiers only do DNS lookups. Our free tier performs actual SMTP mailbox verification with a 5-second timeout. Test our accuracy yourself before paying a cent.

One API Key, Six APIs

Your ParheliaWeb key works across Email Validation, Funding Rounds, Layoffs, Regulatory Fines, Acquisitions, and IPOs. Separate quotas, one portal, zero integration friction.

Built in the Netherlands, GDPR Compliant

All data processing complies with GDPR. Email addresses are SHA-256 hashed — never stored in plain text. Our servers are in Dutch data centers, not US cloud regions.

Pricing Aligned with Real Costs

Email validation has live SMTP infrastructure cost per check. Data APIs query our cached database. Different costs, different free quotas — and we tell you exactly why.

Same Key, Seamless Upgrade

Upgrade any API tier instantly in your portal. Your API key never changes. Your code never breaks. No migration, no re-integration, no surprises.

Not Just for Developers

Sales teams, recruiters, investors, and compliance officers use ParheliaWeb data to spot opportunities and risks before the competition.

Sales & Business Development

Track funding rounds to identify companies with fresh capital and buying power. Time your outreach when they're most likely to invest in tools.

Recruiters & Talent Teams

Monitor layoffs to find available talent pools. Track acquisitions to identify companies restructuring their teams and hiring needs.

Compliance & Risk

Track regulatory fines across jurisdictions. Identify patterns in enforcement actions before they affect your portfolio or partners.

Investors & Analysts

Follow IPO pipelines and M&A activity. Get structured data on deals, valuations, and investor syndicates — not just headlines.

From Raw Data to Actionable Intelligence

Our APIs return structured, verified data — but what matters is what you do with it.

Example: A sales team queries our Funding API weekly for Series B rounds in fintech. They cross-reference with LinkedIn, identify new VPs of Engineering at funded companies, and time their SaaS pitch to coincide with budget expansion. That's the ParheliaWeb edge.

No code required for exploration — use our portal to browse data before you automate.

🗝️ One Key, Six APIs — The ParheliaWeb Platform

Most API vendors sell you one product and one integration. We built six.

Your ParheliaWeb API key unlocks Email Validation, Funding Rounds, Layoffs, Regulatory Fines, Acquisitions, and IPOs. Each has its own quota, tracked in one portal. Upgrade individual APIs as you grow — or keep using free tiers for the rest.

This isn't a bundle. It's a platform. And it's built the same way we build everything: transparent, fair, and developer-first.

Why Our Free Tiers Have Different Quotas

We don't do one-size-fits-all pricing. Different infrastructure, different costs, different limits — and we tell you exactly why.

Email Validation: 100/month

Every check opens a live SMTP connection to an external mail server. Timeouts, retries, IP reputation management — each validation has real infrastructure cost. We align the free quota with what we can sustainably offer.

Data APIs: 100/day each

Funding, Layoffs, Fines, Acquisitions, and IPOs query our own cached, indexed database. Low marginal cost per query. We can be more generous because the infrastructure is ours and the data is pre-processed.

We believe transparency doesn't stop at the API response. Most email verification tools hide their real costs behind "contact sales" and expiring credits. We don't. Our pricing is open, flat, and fair — because that's how we build everything.

Frequently Asked Questions

Does ParheliaWeb perform real SMTP verification on the free tier? +
Yes. Unlike most competitors who limit free tiers to DNS lookups, ParheliaWeb's free tier performs actual SMTP mailbox verification with a 5-second timeout, plus confidence scoring and dynamic spam pattern detection. You get the same verification engine as our paid customers — just with a lower monthly quota.
Can I use one API key for all ParheliaWeb APIs? +
Yes. Your ParheliaWeb API key works across all six APIs: Email Validation, Funding Rounds, Layoffs, Regulatory Fines, Acquisitions, and IPOs. Each API has its own quota, managed from a single portal. Upgrade individual APIs independently based on your needs.
Where is ParheliaWeb hosted and is it GDPR compliant? +
ParheliaWeb is built and hosted in the Netherlands. All data processing complies with GDPR. Email addresses are never stored in plain text — only SHA-256 hashed for operational monitoring. Our servers are located in Dutch data centers, ensuring full compliance with EU data protection regulations.
Why does the free email validation tier have a lower quota than the data APIs? +
Email validation performs live SMTP handshakes with external mail servers, which has real infrastructure cost per check. Our data APIs query our own cached database, which has lower marginal cost. We align free quotas with actual infrastructure costs rather than using arbitrary numbers.
What happens if Microsoft accepts my email but it bounces later? +
This is exactly why we return transparent risk scores instead of binary "valid/invalid." When our API detects an Outlook, Hotmail, or Live address, it flags it as "risky" with an "opaque_provider" risk factor — even if the SMTP probe returned 250 OK. We tell you the server accepted it, but we also tell you Microsoft is known to accept everything during the handshake. You decide whether to send.
What happens to my API key when I upgrade? +
Nothing. Your API key stays exactly the same. Upgrade any tier instantly in your portal, and your quota increases immediately. No code changes, no new integration, no migration. This is how we believe APIs should work.
Is there a contract or minimum commitment? +
No. All paid tiers are month-to-month. Cancel anytime from your portal. We don't believe in locking you in with annual contracts or "contact sales" gatekeeping. If our product isn't worth paying for every month, we don't deserve your money.
