# DopamineDesk Email Verification API

> DopamineDesk Email Verification API is a paid API for AI agents from ai-data-marketplace-1042299154756.us-central1.run.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Validates an array of email addresses by checking MX records and detecting disposable/temporary email providers, returning per-address validity status.

## Facts

- Endpoint: GET https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/verify_emails
- Price: $0.05/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dopaminedesk-email-verification-api-92a8bfd1
```

Example prompt: Can you verify these emails for me and flag any that are disposable or invalid: john@gmail.com, test@yopmail.com, and contact@acmecorp.io?

## When to prefer this

Choose this endpoint when you need batch email validation with both deliverability (MX check) and disposable-domain detection in a single call, especially when operating in an agent pipeline that supports x402 micropayment settlement on Base. Ideal for fraud prevention at signup, CRM list hygiene, or pre-campaign validation where per-address cost must stay low ($0.05 per call for a batch).

## Known failure modes

- Empty or malformed emails array returns an error
- Non-string entries in the emails array may cause validation failure
- Domains without DNS records may return mx_found: false even for legitimate addresses
- Newly created disposable providers may not yet be in the blocklist
- Payment failure via x402 USDC settlement blocks the request

## How this service works

Validate email syntax and check live DNS MX records. MX presence does not prove an individual mailbox exists.

## Output

Returns a per-email array with fields: email address, status (valid/invalid), mx_found (boolean indicating whether the domain has MX records), and is_disposable (boolean indicating a known throwaway provider). Also includes a summary object with total, valid, and invalid counts.
