> Ambolt Disposable Email Check is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Checks whether an email address is disposable/temporary, validates syntax, estimates deliverability, and checks MX records via a pay-per-call API.

## 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 ambolt-disposable-email-check-d31ab59c
```

Example prompt: Can you check whether someone@mailinator.com is a disposable or throwaway email address, and tell me if it has valid MX records and whether it looks deliverable?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call disposable email check with MX validation, syntax checking, role-address detection, and deliverability estimation in a single call — especially in agentic or automated pipelines that pay per use via x402 rather than managing a subscription. Prefer it over roll-your-own regex checks when you also need DNS-level MX verification and an up-to-date CC0 disposable domain list.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Email exceeding 254 characters is rejected
- DNS lookup failures are reported in the dnsError field rather than causing a hard failure
- Unknown or brand-new disposable domains may not yet appear in the CC0 list, causing false negatives
- Non-existent domains may return hasMx=false with a DNS error

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

Returns a JSON object with: the email and domain checked, a boolean disposable flag, whether it's a role address, syntax validity, MX record presence, any DNS errors, a deliverable estimate (e.g. 'risky', 'safe'), a typo suggestion if applicable, the timestamp of the check, and the source list used for disposable classification.
