Abstract API offers standalone REST APIs for email validation, geolocation, and more. See pricing per API, features, pros and cons, and FAQs.
Abstract API is a collection of standalone developer REST APIs covering common backend data tasks, including email validation, IP geolocation, phone validation, company enrichment, exchange rates, and fraud scoring. Founded in 2020 and headquartered in San Francisco, it targets engineering teams that would rather call a pre-built API than build and maintain this logic themselves.
Despite the similar name, Abstract API is a completely separate company from Abstract (goabstract.com), the design version-control tool; Abstract API operates exclusively as a backend data API provider with no design or collaboration features.
Each API is sold, documented, and billed as its own product, so teams typically choose the specific endpoints they need rather than subscribing to a single unified platform.
The Email Validation API checks deliverability, syntax, and disposable or role-based addresses, while the Phone Validation API verifies and formats international numbers and identifies carrier and line type.
The IP Geolocation API resolves IP addresses to location, timezone, and connection type data, and the Company Enrichment API looks up firmographic data by company name or domain, useful for lead enrichment.
Additional APIs cover VAT validation, currency exchange rates, public holidays, and email reputation and fraud scoring, all accessible through simple REST calls with per-API documentation and dashboards.
Every Abstract API endpoint has its own free tier, restricted to non-commercial or evaluation use, and its own paid subscription tiers for production traffic, starting at roughly 17 dollars per month per API.
Because pricing is per API rather than bundled, teams using multiple endpoints together, such as email validation, geolocation, and company enrichment, pay for each subscription separately, which can add up quickly at scale.
Enterprise plans offer custom pricing with SLAs up to 99.99 percent and SSO support across the suite; billing is month-to-month by default with overage fees for exceeding request limits.
Abstract API is a collection of individually sold developer APIs covering tasks like email validation, IP geolocation, phone validation, company enrichment, and exchange rates, aimed at engineering teams that need pre-built data endpoints.
No. Abstract API (abstractapi.com) is a developer API provider founded in 2020, completely separate from Abstract (goabstract.com), which is a design version-control tool for Sketch and Figma files.
Each API has a free tier, but free usage is restricted to non-commercial or evaluation purposes. Production use requires a paid subscription on each API used.
Paid plans start at roughly 17 dollars per month per individual API, with higher tiers unlocking more requests, faster response times, and better data quality; enterprise pricing is custom.
Yes, but each API, for example Email Validation and IP Geolocation, is billed as a separate subscription, so using several APIs together means paying for each one individually.
Abstract API is headquartered in San Francisco, United States.
Enterprise plans advertise up to 99.99 percent SLA along with SSO and SAML support, available via custom quote.
Abstract API is a REST-based service, so it can be called from any language capable of making HTTP requests, and the company provides documentation and code samples for common languages.
