Real-Time APIs

One identity. Multiple kinds of intelligence.

Identity decisions happen in milliseconds of business logic. A customer submits an email. A lead enters the funnel. An account is created. A transaction is initiated. A profile needs to be recognized.

AtData brings validation, identity resolution, enrichment, behavioral intelligence, and risk signals directly into those workflows so your systems can act on better identity context without slowing down the user.

Submit an identity. Return the intelligence. Keep the decision where it belongs.

AtData’s APIs are designed around the decisions organizations make about identity, not around a single application. Depending on the use case, an email address alone or combined with other known attributes can be used to validate data, resolve identities, enrich profiles, or assess risk.

Validate

Determine whether an email identity is usable.

Evaluate an email address for validity and risk, returning structured results that can distinguish SafeToSend, valid, invalid, catch-all, trap, disposable, role-based, and other conditions. Suggested corrections can also be returned when applicable.

Use it during:

• Lead capture
• Registration
• Checkout
• Account creation
• CRM updates
• Other data-entry workflows

Validate Identities

Resolve

Connect one identity to another.

AtData matches the identity information you already have to find additional points of contact to recognize relationships that would otherwise remain fragmented across records and channels.

Available matching capabilities include:

• Email to alternate emails
• Email to postal identity
• Postal identity to email

Resolve and Link Profiles

Understand

Add customer context in real time.

Get a variety of demographic and behavioral attributes for a matched identity. Use enrichment when the decision benefits from more context than your first-party record provides.

Applications include:

• Lead qualification
• Segmentation
• Personalization
• Customer analysis
• Profile completion
• Model enrichment

Understand Customers

Assess

Determine identity risk before you act.

Fraud prevention evaluates an email identity and can incorporate additional information such as name, postal address, IP, and other available context to return fraud-risk intelligence.

Use it to strengthen:

• Account opening
• Customer onboarding
• Promotion eligibility
• Transaction decisions
• Identity-risk assessment
• Proprietary fraud models

Assess Identity Risk

Put intelligence where the decision already happens.

AtData APIs are not intended to replace the systems running your business. They are designed to make those systems better informed.

API Documentation

1. Send what you know.

Submit the available identity data when a relevant customer interaction occurs. Depending on the API, that may be as simple as an email address or may include supporting identity attributes.

2. AtData evaluates the identity.

The request is evaluated against the AtData intelligence appropriate to the service—including validation, identity relationships, demographic data, behavioral activity, or fraud signals.

3. Receive structured intelligence.

Responses return defined fields, statuses, attributes, linkages, or risk information your systems can interpret programmatically.

4. Apply your own decision logic.

Your business determines the outcome. AtData provides the intelligence layer. Your workflow remains in control.
Accept. Correct. Match. Enrich. Prioritize. Challenge. Review. Decline.

Start simple. Go deeper when the decision requires it.

Not every interaction needs the same amount of intelligence.

• A newsletter form may need email validation.
• A returning customer may need identity matching.
• A new lead may benefit from enrichment.
• A financial application may require behavioral and fraud signals alongside submitted identity data.

That allows organizations to introduce AtData at the level appropriate to each decision rather than forcing every workflow through the same process. It also creates a common identity foundation across teams that may otherwise purchase and evaluate data independently.

Growth and risk can consume different intelligence from the same underlying identity.

Designed for developers. Built for enterprise workflows.

AtData’s data services APIs use REST endpoints, HTTPS, API-key authentication, and structured response objects. The documentation includes request parameters, response schemas, examples, status definitions, and an interactive API playground.

Supported implementation patterns

• Real-time individual requests
• Synchronous bulk requests for supported services
• Large asynchronous list processing
• Existing application and workflow integrations
• API access configured by service and returned data

For workloads that do not require individual real-time decisions, AtData also supports bulk and list-based processing.

Choose the intelligence. Keep your architecture.

AtData fits into the environments enterprises already use for customer and identity decisions. The objective is not to add another destination. It is to improve the information moving through the architecture you already have.

Connect identity intelligence to:

• Registration and onboarding
• Ecommerce and checkout
• CRM and CDP platforms
• Fraud and risk engines
• Customer-data pipelines
• Lead-management systems
• Data warehouses
• Analytics environments
• AI and machine-learning models
• Proprietary applications

Why AtData

The API is only as valuable as the intelligence behind it.

An endpoint is easy to replicate. Decades of identity history are not.

AtData APIs provide access to an intelligence foundation built around persistent email identity, billions of identity relationships, longitudinal history, behavioral activity, validation intelligence, enrichment data, and fraud signals.

The API makes that intelligence usable at the precise moment your systems need it.

---

Add more context to your next identity decision.

Whether you need to validate an email, recognize a customer, enrich a profile, or evaluate risk, AtData brings identity intelligence directly into the workflow responsible for what happens next.
