Features

Screen unwanted callers with clear, reviewable signals.

Spam Check API

Spam Check API Proposed | HappyAssist

What a useful screening response might contain

A narrowly defined result such as suspected spam, likely legitimate or insufficient information, along with a confidence indicator and the signal timestamp where supported. A recommendation should be treated as a signal, not a permanent fact about a person or telephone number. Phone numbers are recycled, businesses share lines and legitimate automated calls can resemble spam. A developer should know the difference between the raw score, a business-configured decision threshold and the action its own product chooses to take.

Protect legitimate callers

False positives matter. A new customer might call from a number not seen before, an accessibility service might use a relay or an existing client might be calling through a shared office line. Screening policies should leave an appropriate review or fallback path rather than silently blocking every uncertain call. The application should record decisions in a way the business can inspect and correct.

Data and operational safeguards

If a spam-screening API is built, document lawful input collection, retention, access controls, permitted use, rate limits and how scores are updated. Avoid promising that every robocall will be detected or that every genuine customer will pass. A service handling phone-number data should specify whether caller content is processed, whether raw numbers are stored and which parties can see the resulting labels.

What must be confirmed before launch

Does the product accept a phone number, a live call event or both? Which countries and number formats are supported? What does each score mean? How current is the data? What are the latency and availability limits? Engineering must provide a real endpoint, authentication method, schemas, errors, usage pricing, test environment and abuse-reporting path before this becomes publishable API documentation.

Use HappyAssist’s receptionist screening today

For businesses that need relief from unwanted calls now, the existing receptionist’s spam-screening capability is the relevant feature to discuss during a demo.

Do not suggest a separate developer API is included with an AI receptionist plan unless it has been released and appears in the actual plan terms.

FrequentlyAsked Questions

Is a standalone HappyAssist Spam Check API available?

Public availability could not be verified. The published product advertises spam screening as part of its receptionist.

Would a spam score be a guarantee?

No. It would be a probabilistic signal that requires careful thresholds and a way to handle uncertain cases.

Can I integrate it into my app today?

Request an engineering availability check before planning around any standalone API.
