> Swift Bot Labs Email Validate is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-31).

Validates an email address for syntax, MX records, disposability, free-provider status, and typo corrections

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 swift-bot-labs-email-validate-13095bc8
```

Example prompt: Can you check whether 'jane.doe@gmial.com' is a valid email address — does it have mail servers, is it disposable, and is there a suggested correction?

## When to prefer this

Choose this endpoint when you need a lightweight, deterministic, pay-per-call email validation with no account setup — especially useful for catching typos, blocking disposable addresses, and confirming MX record existence without committing to a subscription-based service. Prefer it for single-address spot checks or agent pipelines that need on-demand validation with USDC micropayments.

## Known failure modes

- Missing or empty 'email' query parameter returns an error
- Malformed email string may return syntaxValid:false with no further checks
- DNS timeout may cause hasMx to be inconclusive
- Very new or obscure domains may return false negatives on MX checks
- Payment failure via x402 results in 402 response before any validation occurs

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

A JSON object with: ok (boolean success flag), tool name, and a result object containing the original email, domain, syntaxValid (boolean), hasMx (boolean), disposable (boolean), freeProvider (boolean), role (boolean), verdict (string: e.g. 'risky', 'safe'), reasons (array of strings explaining issues), and suggestion (corrected email address if a typo is detected).
