## What this connects

Abstract API provides a suite of APIs for developers to automate various tasks, including data validation, enrichment, and more.

Vendor: https://www.abstractapi.com/

## Tools available

**3** tools available. First 3:

- `ABSTRACT_EMAIL_REPUTATION_API` — Email validation and quality check — Validate 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.
- `ABSTRACT_GET_VAT_CATEGORIES` — Get VAT Categories — Tool 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.
- `ABSTRACT_IBAN_VALIDATION_API` — Validate IBAN — Tool to validate the format and country code of an IBAN number. Use after collecting an IBAN to ensure it is correctly formatted.

## Auth

Auth schemes: `API_KEY`.

## How agents use Abstract

Inside a Definable workflow, Abstract is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Abstract** — the Researcher (GPT-5.5) pulls context from Abstract (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Abstract** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Abstract (create record, post message, draft email).
- **Designer / Engineer → Distributor → Abstract** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Abstract (attach file, open PR comment, post status).

The Verifier checks every Abstract call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
