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.
Example use cases
Block disposable emails at signup
“Before I let this user register with the email temp-user@guerrillamail.com, can you check if it's a disposable or temporary address and tell me the deliverability risk?”
Email list hygiene before a campaign
“I'm about to send a marketing email to info@somedomain.biz — can you verify whether that address is a role-based or disposable email and whether the domain has working MX records?”
Fraud screening in payment flow
“This user just entered throw123@mailnull.com as their email during checkout — is this a known disposable email provider, and is the syntax valid?”
Technical details
Endpoint
GEThttps://api.ambolt.dev/v1/disposable-email-check?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
