| Tool | What it says it does |
|---|---|
bulk_email_security_score | Score up to 100 domains' email security in one call (SPF 30, DMARC 40, DKIM 25, MX 5 from live DNS): per-domain score, grade and issues, plus a summary with grade counts, domains missing DMARC or SPF, and the worst 10. For MSPs and agents checking a client or vendor list. Costs $0.50 USDC via… |
check_domain_email_security | Free. Look up a domain's MX, SPF (record, DNS lookup count, all qualifier), DMARC (policy, rua) and DKIM (common selectors, key size) from live DNS and list issues. No payment. |
check_email_address | Check one email address: syntax, MX / null MX, disposable domain, role account, free provider; verdict ok / risky / undeliverable. No SMTP probe. Costs $0.01 USDC via x402; errors are not charged. |
email_fix_plan | Email security fix plan for one domain: the exact SPF, DKIM and DMARC records to publish (create / replace / keep, name, value, why), in order, with click-path steps for the domain's DNS host and a staged DMARC rollout. Non-sending domains get a lock-down set. Costs $1 USDC via x402; errors are… |
email_security_score | Grade a domain's email security 0-100 (A-F): SPF 30, DMARC 40, DKIM 25, MX 5, from live DNS, with findings and the top 3 fixes. Read-only. Costs $0.01 USDC via x402; errors are not charged. |
email_security_score_batch | Score 2 to 5 domains' email security in one call (the same SPF/DMARC/DKIM/MX score, grade and findings as email_security_score), lowest score first. Costs $0.04 USDC via x402; if no domain can be scored it errors and is not charged. |
pricing | Free. Prices of the paid tools, payment network and receiving address. |
watch_status | Free. Status of a paid email setup watch (created with POST /v1/watch): items, expiry, last check, last webhook delivery and current SPF/DMARC/DKIM/MX state. Needs the webhook_secret from creation. |
In its maker's words
