Tools
| Tool | Description | Behaviour |
|---|---|---|
| domain_check | Does the domain accept mail, which MX hosts, is it a disposable or free-mail provider, does it publish SPF and DMARC (and the DMARC policy)? Use before trusting a sender domain or when onboarding a company. Example: domain 'noahsarch.tech'. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. No logging of addresses. | Read-only |
| extract_emails | Find every address in a block of text or HTML (deduped by default). Free. Pair with verify_emails. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. No logging of addresses. | Read-only |
| suggest_fix | Fix common typos: gmial.com, hotmail.con, yaho.com, stray spaces/dots. Returns the suggestion (or null) and which fixes applied. Free. Example: email '[email protected]'. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. No logging of addresses. | Read-only |
| verify_email | Full check of one address: RFC syntax and normalisation, domain existence and MX records (incl. null-MX and implicit-MX), disposable-provider list (10k+ domains), role account, free-mail provider, typo suggestion; optional SMTP RCPT probe with catch-all detection and optional SPF/DMARC. Example: email '[email protected]', smtp_check false. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. No logging of addresses. | Read-only |
| verify_emails | Same checks as verify_email for a list, run in parallel with per-domain DNS caching; returns per-address results, a summary by status, and `clean` (the deliverable ones). Charged per unique address. Example: emails ['[email protected]','[email protected]'], smtp_check false. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data_version, warnings[] and a disclaimer. No logging of addresses. | Read-only |
