Abstract API provides a suite of APIs for developers to automate various tasks, including data validation, enrichment, and more.
Abstract API provides a suite of APIs for developers to automate various tasks, including data validation, enrichment, and more. On Nagent, Abstract is exposed as a fully-configurable developer tools integration that any agent can call — 3 actions, and API key authentication. No code is required to wire Abstract into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Abstract to automate the kinds of tasks developer tools teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Abstract into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Abstract, with input parameters and output schema. Drop these into any step of an agent built in Helix.
ABSTRACT_EMAIL_REPUTATION_APIValidate email addresses and assess their deliverability and quality. Returns comprehensive validation data including format checks, disposable email detection, free provider identification, role-based email detection, MX records verification, and SMTP validation. Use this to verify email addresses before sending, filter out risky or low-quality emails, and improve email deliverability rates.
Input parameters
The email address to validate and assess for deliverability and quality.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
ABSTRACT_GET_VAT_CATEGORIESTool to retrieve VAT rate categories for a specific country, including standard, reduced, and special VAT rates. Use when you need to determine applicable VAT rates for different product/service categories in a country.
Input parameters
The two-letter ISO 3166-1 alpha-2 country code to get VAT categories for. Example: 'DE' for Germany, 'FR' for France, 'GB' for United Kingdom.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
ABSTRACT_IBAN_VALIDATION_APITool to validate the format and country code of an IBAN number. Use after collecting an IBAN to ensure it is correctly formatted.
Input parameters
International Bank Account Number to validate, accepts with or without spaces. Example: 'BE71096123456769'.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 90 agents privately built on Nagent that already use Abstract.
Build on Nagent
Connect Abstract to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Abstract, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Abstract is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Abstract is connected, you configure its 3 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Abstract steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Abstract event fires, the agent kicks off automatically.
Every Abstract action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Abstract ships with 3 pre-built developer tools actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Abstract together with other connected tools.
