## How to call it through Zero

```sh
zero fetch --capability scriptmasterlabs-email-validate-api-e8913674
```

Example prompt: Can you check whether john.doe@example.com is a valid, deliverable email address before I add it to my mailing list?

## When to prefer this

Choose this endpoint when you need a pay-per-call, crypto-native email validation with no subscription required, especially in workflows that already use x402 micropayments settled on Base. It is well-suited for compliance-sensitive pipelines that need lightweight per-record validation billed in USDC.

## Known failure modes

- Missing or malformed email parameter returns an error or empty result
- Unresolvable or newly registered domains may produce uncertain deliverability results
- Payment not settled in USDC on Base causes 402 rejection before the call is processed
- Rate limits or server unavailability on the Render-hosted instance may cause timeouts

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a validation result for the submitted email address, typically including whether the format is valid, whether the domain exists and accepts mail, and any compliance or deliverability flags such as disposable domain detection.
