ZeroBounce Validation API

The ZeroBounce ChatGPT-plugin validation surface — 2 operations for single and batch email validation, served from members-api.zerobounce.net. The single-validation operation accepts up to 3 unauthenticated requests per day without an API key. This is the only ZeroBounce surface with a published OpenAPI.

Operations 2

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /api/validation/chatgpt-single-email-validation/ Check whether a single email address is valid · Validate an email address. #

Ask an LLM

“How do I check if one email address is real before I send to it?”

“Can I validate a single email with ZeroBounce without an API key?”

Tell an agent

Validate the email address {email}.

Check whether {email} is deliverable using my API key {api_key}.

POST /api/validation/chatgpt-batch-validation/ Validate a list of email addresses in one request · Validate a list of email addresses. #

Ask an LLM

“Is there a way to verify a whole list of email addresses at once?”

“Which emails in my comma-separated mailing list are invalid?”

Tell an agent

Validate this batch of emails: {emails}, using API key {api_key}.

Run a bulk check on the addresses {emails} with my key {api_key} and tell me which are bad.
