Check email addresses for syntax, MX and disposable domains. $0.0015/call via x402.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"email-address-check-syntax-mx-disposable-spf-dma","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
