# EmailCheck EmailCheck is an email verification API. It checks an email address at domain level: syntax, domain existence, MX routing, disposable-domain and role-account signals, likely typos with a correction suggestion (e.g. gmial.com -> gmail.com), domain age in days from RDAP registration records (null when no record exists, never estimated), and a catch-all risk signal (low / possible / unknown) inferred from MX and provider patterns and labelled as a signal, not a probed conclusion. Every result carries a 0-100 score and a verdict: valid (score 80 or above with MX present), risky (50-79, or a likely typo), invalid. Every response carries scope: "domain-level" and a note stating exactly what was checked. What EmailCheck does NOT do: it does not probe whether an individual mailbox exists (no SMTP probing), and a valid result does not confirm a mailbox exists. ## API Base URL: https://emailcheck-api.pages.dev - GET /validate?email=... — validate one address - POST /validate — same check, JSON body {"email": "..."} - POST /validate/batch — JSON body {"emails": ["...", ...]}, up to 100 addresses; per-address results in submission order plus a summary {total, valid, risky, invalid, disposable, typoLikely} with counts and percentages. Batch errors are named JSON: MISSING_EMAIL, EMPTY_BATCH, BATCH_TOO_LARGE, INVALID_JSON. A bad entry marks only itself invalid; it never fails the batch. ## Pricing (subscriptions run on the marketplaces) RapidAPI (https://rapidapi.com/binbin7418/api/emailcheck-email-validation-api): - BASIC: free, 100 calls per month - PRO: $9/month, 10,000 calls per month - ULTRA: $29/month, 50,000 calls per month api.market: Free Trial 7 days with 100 calls; Pro $9/month; Ultra $29/month; overage $0.002 per extra request.
