Pricing overview
Host.io utilizes a credit-based pricing model, where API requests consume a specific number of credits. The platform offers a free Developer Plan and several paid subscription tiers, each providing a monthly allocation of credits. This structure allows users to select a plan that aligns with their anticipated API usage for services such as domain data queries, reverse IP lookups, and domain searches. Higher-tier plans generally offer a lower cost per credit as detailed on Host.io's pricing page.
The credit system applies across Host.io's core products, including the Domain API, Reverse IP API, and Domain Search API. The cost of individual API calls varies depending on the endpoint and the complexity or depth of the data requested. For instance, a simple domain lookup might consume fewer credits than a comprehensive reverse IP search retrieving multiple associated domains.
Understanding the credit consumption rates for specific API endpoints is crucial for managing costs effectively. Developers can monitor their credit usage through their Host.io dashboard. For scenarios requiring very high volumes of API calls or specialized features, custom enterprise plans are available.
Plans and tiers
Host.io offers a range of plans designed to accommodate different levels of usage, from individual developers to large enterprises. Each plan provides a fixed number of credits per month, with options for additional credits if the base allocation is exceeded. Plans are structured to provide a better per-credit value at higher volumes.
| Plan Name | Monthly Price | Monthly Credits | Key Features/Limits | Best For |
|---|---|---|---|---|
| Developer | Free | 500 | Access to core APIs, rate limits apply | Testing, small personal projects, evaluation |
| Starter | $19 | 25,000 | Increased rate limits, standard support | Small businesses, startups, moderate data needs |
| Pro | $49 | 100,000 | Higher rate limits, priority support, more concurrent requests | Growing businesses, frequent data analysis, competitive intelligence |
| Business | $199 | 500,000 | Advanced rate limits, dedicated support, API usage analytics | Large-scale market research, extensive security intelligence |
| Enterprise | Custom | Custom | Tailored features, dedicated infrastructure, SLA, custom credit volumes | Organizations with high-volume, mission-critical requirements |
When selecting a plan, users should consider their anticipated monthly API call volume and the specific credit cost per request for the APIs they intend to use. Overages beyond the monthly credit allocation are typically billed at a per-credit rate, which may be higher than the effective per-credit cost of a larger plan. Details on specific credit consumption for various API calls are available within the Host.io API documentation.
Free tier and limits
Host.io provides a free Developer Plan, offering 500 credits per month. This tier is designed for evaluation, testing, and small-scale personal projects. It allows developers to integrate with Host.io's APIs and understand their functionality without an initial financial commitment. The free tier includes access to the core Domain API, Reverse IP API, and Domain Search API.
While the Developer Plan offers full API access, it comes with certain limitations:
- Credit Limit: 500 credits per month. Once exhausted, API calls will fail until the next billing cycle or an upgrade to a paid plan.
- Rate Limits: Requests per second (RPS) are typically lower on the free tier compared to paid plans to ensure fair usage and system stability.
- Support: Support may be community-based or have a lower priority compared to paid plans.
- Features: Core features are available, but advanced analytics or dedicated infrastructure options are reserved for higher tiers.
The free tier serves as an entry point for developers to experiment with domain data. For any production environment or application requiring consistent, higher-volume API access, upgrading to a paid plan is recommended. The 500 monthly credits are sufficient for initial testing of integrations or occasional lookups.
Real-world cost examples
To illustrate Host.io's credit consumption, consider common API operations and their approximate credit costs. These are illustrative examples; actual credit costs per API call are specified in the official Host.io documentation.
Scenario 1: Basic Domain Information Lookup
- Operation: Retrieving basic information for a single domain (e.g., creation date, registrar).
- Estimated Credit Cost: 1 credit per request.
- Usage Example: A cybersecurity analyst performing 100 daily lookups for suspicious domains.
- Monthly Credits: 100 lookups/day * 30 days = 3,000 credits.
- Cost: This would fit within the Starter Plan (25,000 credits for $19/month), with ample credits remaining.
Scenario 2: Reverse IP Lookup
- Operation: Identifying all domains hosted on a specific IP address. This can be more credit-intensive if many domains are found.
- Estimated Credit Cost: 5-10 credits per request, potentially more for extensive results.
- Usage Example: A competitive intelligence firm monitoring 50 competitor IP addresses daily for new associated domains.
- Monthly Credits: 50 lookups/day * 10 credits/lookup * 30 days = 15,000 credits.
- Cost: This usage also falls within the Starter Plan (25,000 credits for $19/month).
Scenario 3: Bulk Domain Search (e.g., by technology)
- Operation: Searching for domains that use a specific web technology across a large dataset. This can involve iterating through results.
- Estimated Credit Cost: Varies significantly based on search complexity and number of results. A single search might cost 10-50 credits, with additional credits for pagination.
- Usage Example: A market researcher identifying 5,000 domains using a particular e-commerce platform monthly, requiring multiple paged requests.
- Monthly Credits: Assuming 2 credits per result for a paged search, 5,000 results * 2 credits/result = 10,000 credits. Plus initial search costs. Total could be 15,000-20,000 credits.
- Cost: This could still be managed within the Starter Plan ($19/month) or require moving to the Pro Plan (100,000 credits for $49/month) if the search patterns are more extensive or frequent.
These examples highlight that for many common use cases, the Starter Plan offers a substantial number of credits. Projects requiring very deep or wide-ranging data collection will likely benefit from the Pro or Business plans due to the improved per-credit cost and higher rate limits.
How the pricing compares
When evaluating Host.io's pricing, it is useful to compare its credit-based model and tiers against alternative domain data providers. Common alternatives include WhoisXML API, BuiltWith, and SecurityTrails, each offering similar or complementary services but often with different pricing structures.
WhoisXML API, for example, offers various APIs for WHOIS data, IP geolocation, and domain intelligence. Their pricing is also credit-based, but credit consumption rates and package costs differ. For instance, WhoisXML API's pricing structure includes a free plan with 500 credits/month, similar to Host.io, and paid plans starting at $49/month for 5,000 credits, which offers fewer credits than Host.io's Starter Plan at a higher price point. This suggests Host.io may offer a more cost-effective entry point for moderate credit volumes.
BuiltWith focuses on website technology profiling and sales intelligence. While it offers API access, its primary model often involves subscriptions for access to its database and reporting tools, rather than a strict per-API-call credit system for raw data. Their pricing tends to be higher, reflecting the curated intelligence they provide rather than raw domain data lookups. For example, BuiltWith pricing starts around $295/month for their API access, indicating a focus on larger business intelligence needs rather than individual domain lookups.
SecurityTrails provides a comprehensive suite of domain and IP data for cybersecurity professionals. Their pricing model combines subscription tiers with credit usage for specific data points. Like Host.io, SecurityTrails offers a free tier for limited access. Paid plans typically start at a higher price point than Host.io, often reflecting the depth of historical data and advanced security features included. For instance, SecurityTrails' pricing for their API starts at $49/month for 10,000 API requests, which is fewer credits than Host.io's $19/month Starter Plan.
Overall, Host.io's pricing, particularly its Starter Plan, appears competitive for developers and small to medium-sized businesses requiring substantial monthly domain and IP data lookups. Its free tier offers a comparable starting point to some competitors. For higher volumes, users should conduct a detailed comparison of per-credit or per-request costs across providers for their specific use cases, as consumption rates and included features can vary significantly. The availability of developer SDKs for Host.io in Python, Go, and Node.js can also influence total cost by reducing development time.
