Fresh proxy detection API for fraud teams
Solarflare API gives fraud, security, and data teams a fresh proxy and VPN intelligence signal — identify IPs recently observed in proxy infrastructure and enrich your risk decisions through a simple API or bulk file analysis.
Built for fraud prevention, bot detection, threat intel, and traffic quality teams.

A fresh proxy intelligence signal, ready to drop into the risk stack you already run.
Six capabilities designed for fraud, security, and data teams that need a recent, observation-based signal — not a stale IP blocklist. Built to complement existing IP intelligence and bot-detection tools, not replace them.
Fresh observed proxy signals
Continuously updated IP intelligence from active network testing — not a stale blocklist that refreshes once a quarter.
- Continuous network testing, daily refresh
- Captures residential and mobile proxy IPs
- Designed for recency, not historical coverage
Simple API lookup
Submit an IP address and get a clean risk signal in milliseconds — observed_proxy boolean, confidence, last seen, network type.
- Single GET /v1/ip/:ip endpoint
- Bearer-token auth, no SDK lock-in
- Sub-200ms typical response
Bulk IP analysis
Submit large lists of IPs for enrichment and scoring — for offline fraud reviews, batch analytics, and historical investigations.
- Millions of IPs per batch
- API or file upload (CSV, JSONL)
- Aggregate breakdowns + per-IP detail
Last-seen timestamps
Every observation comes with a last_seen date — so you can decide whether the signal is hot, warm, or historical.
- ISO-8601 last_seen on every record
- Configurable freshness windows
- Decay-friendly for risk models
Confidence scoring
Each signal is scored low, medium, or high — so you can tune blocking thresholds without writing your own probabilistic model.
- low / medium / high confidence levels
- Network-type classification included
- Threshold-friendly for fraud rules
Cross-network connections
One observed proxy signal, plugged into every IP intelligence, fraud, and bot-detection system you already run.
- Plugs into MaxMind, IPinfo, and others
- Connects fraud, SIEM, bot-detection, and threat intel
- Webhook + REST integration patterns
One request. A clean risk signal.
Solarflare API answers a simple question: has this IP recently been seen operating through proxy infrastructure? The response is small, stable, and easy to plug into existing fraud rules, bot detection systems, and IP intelligence pipelines.
- One GET endpoint, one IP, one clean JSON response
- observed_proxy boolean, confidence, last_seen, network_type
- Bearer-token auth — no SDK lock-in, drop into any stack
- Sub-200ms typical latency, inline-safe at signup and login
- Bulk endpoint for offline reviews and historical analysis

Solarflare API is designed to drop into the risk, fraud, and detection systems you already run — adding a fresh observed proxy signal without changing your architecture.
Fraud prevention
Flag suspicious signups, logins, and payments with a fresh proxy intelligence signal — catch identity theft and account takeover before they convert.
Bot detection
Improve detection of automated traffic with a network-level signal that residential and mobile bots can't easily route around.
Ad-tech & traffic quality
Detect proxy-driven click fraud, impression fraud, and low-quality traffic — protect campaign budgets and uphold inventory standards.
Threat intelligence
Enrich IP reputation pipelines and SIEM dashboards with recently observed proxy infrastructure for stronger context on inbound activity.
Marketplaces
Add observed proxy signals to onboarding, account-trust, and listing-quality scoring — reduce abuse and protect honest sellers and buyers.
Fintech & payments
Strengthen risk decisions on transactions, KYC, and onboarding flows — proxy-aware scoring without rewriting your risk engine.
Median lookup
Inline-safe at signup, login, and payment events
Refresh cadence
Continuous observation, daily signal updates
Batch analysis
Millions of IPs per job for offline review
