Snov.io Email Verifier API
Verifies up to ten email addresses per request with multistep SMTP, format, disposable, webmail, and gibberish checks, returning valid, not_valid, or unknown status via the start/result (task_hash) pattern.
OpenAPI Specification
openapi: 3.0.3
info:
title: Snov.io API
description: >-
Snov.io sales engagement REST API. Authentication uses the OAuth2
client_credentials grant to exchange an API User ID (client_id) and API
Secret (client_secret) for a one-hour Bearer access token. Email finder,
domain search, and email verification use an asynchronous pattern: a POST
to a `/start` endpoint returns a `task_hash`, then a GET to the matching
`/result` endpoint retrieves the outcome. Most request bodies are
application/x-www-form-urlencoded; a few v2 endpoints accept JSON. The API
is rate limited to 60 requests per minute.
