How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

Output

Returns a JSON object with a total count of submitted emails, a valid_count, an invalid_count, and a results array containing per-email verification outcomes indicating whether each address is valid or invalid.

Example use cases

Pre-send mailing list cleanup

“I have a list of 50 subscriber emails I collected from our signup form — can you check which ones are actually valid before I send the newsletter? Here they are: alice@example.com, bob@@broken.com, carol@test.org...”

CRM data quality audit

“We just imported a batch of leads into our CRM and I need to know which email addresses are garbage. Can you validate all these emails and give me a count of how many are valid vs invalid?”

User registration fraud filter

“Before we activate these new accounts, can you batch-verify the email addresses they signed up with and flag any invalid ones so we can block them from proceeding?”

Technical details

Endpoint

GEThttps://klymax402.com/api/email-verification/api/verify/batch

When to prefer

Choose this endpoint when you need to validate multiple email addresses in one round trip (up to 100), paying only $0.03 USDC per batch call. It is ideal for bulk list hygiene, pre-send validation, or CRM cleanup scenarios where per-email API calls would be costly or slow. Prefer this over single-email validators when processing lists of more than a few addresses.

Side effects

Array exceeds 100 email limit — may return an error or silently truncate
Malformed input array — missing or incorrectly typed emails field returns an error
Payment failure via x402 — call not processed if USDC balance is insufficient
Network timeout for very large batches near the 100-email limit
Disposable or catch-all domains may not be accurately classified
