flat-rate-llm.kikoribera03.workers.dev/v1/red/email-check

Use when an agent must decide whether to write to an address, or clean a list before sending: it scores one email 0-100 with a verdict (ok, risky, disposable, undeliverable, invalid) and the evidence under it: every point lost is itemised with the field that proves it. 12,141 disposable domains from two maintained open lists pinned to a commit, 4,897 free providers, 1,018 role names, typo fix (gmial.com > gmail.com), live MX/SPF/DMARC. No SMTP probe, no API key.
