FullContact Pricing: Plans, Tiers, and Cost Examples (2026)

Pricing overview

FullContact's API pricing structure is designed to accommodate various usage levels, from individual developers to large enterprises. The model is primarily based on the volume of API calls made, with different tiers offering varying call allowances and feature sets. This allows users to select a plan that aligns with their operational scale and specific data enrichment requirements. The company provides a 'Developer' plan for getting started at no cost, followed by tiered 'Growth' and 'Enterprise' plans. Each plan integrates access to FullContact's core APIs, including the Person API, Company API, and Address API, which are used for lead scoring, customer experience personalization, and CRM data enrichment FullContact pricing page.

The pricing strategy aims to provide flexibility, enabling businesses to scale their data enrichment efforts as their needs evolve. Users requiring higher volumes or specialized support typically transition to custom 'Enterprise' agreements. This approach ensures that both small teams and large organizations can find a suitable option for integrating identity resolution and data enrichment into their workflows. FullContact also emphasizes compliance with data privacy regulations such as GDPR and CCPA across all its service tiers FullContact homepage, which is a key consideration for many technical buyers evaluating data providers.

Plans and tiers

FullContact offers distinct pricing tiers, each structured to address different usage volumes and business needs. The primary plans include a free Developer plan, a Growth plan, and custom Enterprise solutions. Each tier provides access to FullContact's suite of APIs for enriching contact, company, and address data, with differences primarily in the number of API calls included and the level of support provided.

The Growth plan, priced at $99 per month for 10,000 API calls, represents the entry point for paid services. This plan is suitable for businesses that have moved beyond initial testing and require a consistent volume of data enrichment. It includes access to the same core APIs as the Developer plan but at a significantly higher scale. For operations demanding even greater capacity or specialized requirements, the Enterprise plan provides tailored solutions. These custom plans often include features like higher rate limits, bespoke data integrations, and dedicated technical support teams, which are crucial for large-scale deployments and complex data ecosystems FullContact developer documentation. Enterprise pricing is negotiated based on specific usage projections and feature requirements.

Free tier and limits

FullContact provides a free Developer plan designed for users to explore and integrate its APIs without an initial financial commitment. This plan includes a monthly allowance of 100 API calls. The primary purpose of this free tier is to enable developers to test the functionality of FullContact's Person, Company, and Address APIs, experiment with data enrichment workflows, and build initial proof-of-concept applications. It grants access to the fundamental capabilities of the platform, allowing users to understand the data returned and how it can be integrated into their systems. While the call limit is suitable for evaluation and small-scale testing, it is generally insufficient for production environments that require continuous data processing or high-volume enrichment.

The free tier's limitations are primarily focused on the volume of API requests. Exceeding the 100-call limit within a month will require an upgrade to a paid plan or waiting until the next billing cycle for the allowance to reset. There are typically no feature restrictions within the scope of the available API calls, meaning developers can access the full range of data fields and enrichment capabilities that the core APIs offer. The free tier also provides access to standard developer support resources, including documentation and community forums, but usually does not include dedicated technical assistance. This structure ensures that the free plan serves as an accessible entry point to evaluate FullContact's offering before committing to a paid subscription FullContact pricing details.

Real-world cost examples

Understanding FullContact's pricing in practical terms involves considering typical use cases and their corresponding API call volumes. Here are a few scenarios illustrating potential costs:

1. Small Business CRM Enrichment: A small business with 500 new leads per month wants to enrich their CRM data with person and company information. Each lead enrichment might involve 2 API calls (one for person, one for company). This translates to 1,000 API calls per month. This usage falls well within the Growth plan's 10,000-call allowance, costing $99 per month. If the business only needed to enrich 50 leads per month for initial testing, the free Developer plan would be sufficient.

2. Marketing Campaign Personalization: A marketing team plans to personalize email campaigns for 5,000 existing customers by adding missing demographic data. If each customer requires one Person API call, this totals 5,000 API calls. This scenario also fits within the Growth plan's $99 monthly fee. If the campaign were larger, targeting 20,000 customers, it would exceed the Growth plan limit, requiring consideration for an Enterprise plan, where the cost would be custom-quoted based on the volume.

3. Fraud Detection for E-commerce: An e-commerce platform processes 25,000 transactions per month and uses FullContact's Identity Resolution to enhance fraud detection by cross-referencing customer data. Assuming each transaction triggers approximately 1.5 API calls on average for identity verification and enrichment, this would amount to 37,500 API calls per month. This volume would typically necessitate an Enterprise plan due to exceeding the Growth plan's 10,000-call limit. The specific cost would depend on the negotiated enterprise agreement, which might include volume discounts for higher usage.

4. Data Cleansing Project: A company undertakes a one-time project to cleanse and enrich a database of 100,000 existing contacts. If each contact requires 2 API calls (person and company), this is 200,000 API calls. For such a large, potentially infrequent, project, an Enterprise plan would be the only viable option. The cost would be determined by the total number of calls, potentially with a project-based or annual agreement.

These examples illustrate how the volume of API calls directly influences the choice of plan and associated costs. Businesses should estimate their monthly or project-based API call requirements to select the most cost-effective FullContact plan FullContact pricing information.

How the pricing compares

When evaluating FullContact's pricing, it is useful to compare it with alternative data enrichment providers such as Clearbit, ZoomInfo, and Apollo.io. While these platforms offer similar core functionalities like person and company data enrichment, their pricing models and feature sets can differ significantly, influencing the overall cost-effectiveness for specific use cases.

Clearbit: Clearbit often employs a pricing model based on monthly API calls or database records, similar to FullContact. However, Clearbit's entry-level paid plans might start at a higher price point for a comparable number of API calls, or offer different bundling of features. For instance, Clearbit's API pricing for its Enrichment API typically starts at a higher monthly fee for fewer calls than FullContact's Growth plan, though specific pricing details are often enterprise-quoted beyond introductory tiers Clearbit pricing overview. Clearbit is known for its strong emphasis on marketing and sales intelligence, often integrating directly with CRM and marketing automation platforms.

ZoomInfo: ZoomInfo's pricing is generally geared towards larger enterprises and sales teams, often involving annual contracts and a seat-based or credit-based model rather than a simple API call count. Its comprehensive contact and company database, along with sales engagement tools, positions it as a more integrated sales intelligence platform. As such, direct API pricing comparisons can be challenging, as its core offering is often a platform subscription rather than purely pay-per-call API access. The cost for ZoomInfo can be significantly higher than FullContact's Growth plan, reflecting a broader suite of services beyond just data enrichment ZoomInfo pricing request.

Apollo.io: Apollo.io offers a freemium model similar to FullContact, providing a free tier with limited credits or features. Its paid plans are typically tiered based on the number of credits, email sends, and access to its B2B database and sales engagement features. Apollo.io's pricing can be more competitive for users primarily focused on sales outreach and lead generation, as its plans often bundle enrichment with outreach tools. Its entry-level paid plans may offer more credits for a similar price point compared to FullContact's API-focused Growth plan, but the value proposition is often tied to the integrated sales platform rather than just standalone API calls Apollo.io pricing plans.

In summary, FullContact's $99/month Growth plan for 10,000 API calls provides a competitive option for businesses seeking focused data enrichment through API access. Alternatives like Clearbit may have higher entry-level costs for similar API volumes, while ZoomInfo and Apollo.io often offer broader platforms with pricing models that include additional sales and marketing tools, which can result in higher overall costs depending on the required feature set. Developers and technical buyers should carefully evaluate their specific needs for API calls, integrated platform features, and budget to determine the most suitable provider.
