What you get
Max is designed for engineering teams building infrastructure at scale, not developer hobby projects.
The highest call volume of any plan — enough for the most data-hungry pipelines and real-time enrichment flows at hyperscale.
Burst to 10K req/s with no throttling. Engineered for traffic spikes, batch processing, and latency-sensitive production workloads.
Contractual uptime guarantee with credits on breach. Status dashboard at status.hostinfo.com updated every 60 seconds.
A private Slack channel with our core engineering team. Direct access — no tickets, no queues. Issues resolved in minutes.
Invite your entire org. Fine-grained role-based access control. Per-member API key management and audit logs.
IP geo, ASN, privacy detection, abuse scoring, domain WHOIS, DNS, SSL, reputation, backlinks, and more — all included.
Enterprise compliance documentation, DPA templates, and audit reports available on request. Data residency in EU or US.
Push enrichment events to any endpoint. Retry logic with exponential backoff. Dead letter queue for zero data loss.
Real-time and historical call volume, error rates, top endpoints, latency percentiles, and team-level usage breakdowns.
Lightning-fast API
A single request to /v2/ip/{ip} returns geolocation, ASN, company info, privacy scores, abuse signals, carrier data, and hosted domains — all in under 40ms at Max plan speeds.

"We went from hitting rate limits every morning to never thinking about it. Max handles our 80M monthly lookups like it's nothing."
Sarah Chen
Lead Engineer, DevSecOps · CloudGuard Inc.
"The dedicated Slack channel alone is worth the price. Got a critical issue resolved in under 4 minutes at 2am. Nothing else comes close."
Marcus Webb
VP Engineering · DataBridge Labs
"We benchmarked 6 IP intelligence APIs. HostInfo Max hit under 40ms p99 consistently. For real-time fraud detection that matters enormously."

You will receive email alerts at 80% and 95%. Once you reach the limit, API calls return a 429 rate-limit error until the next billing cycle. You can upgrade to Enterprise for overage pricing.
If monthly uptime falls below 99.99%, you receive service credits — 10% of monthly fee per 0.1% of downtime below the threshold. Measured at the API gateway, not individual data sources.
A private shared channel between your team and HostInfo engineers. Not a bot, not a queue — real engineers who know your integration. Typical response time under 10 minutes during business hours, under 30 minutes outside.
Yes. You are charged the prorated difference for the remaining days in your billing cycle. Your limits update instantly upon upgrade.
