All projects on Base matching “email validation”

Validate an email address — syntax, MX/A deliverability lookup, and disposable / role-based address detection. No mailbox probing.

Takes one email address and tells you whether it can actually receive mail. Returns a verdict of valid, invalid, or risky, splits the address into username and domain, and flags free providers and role accounts like admin@ or support@. One address per call.

Parse and normalize postal addresses into structured components. Returns address number, street, city, state, ZIP, and USPS-formatted output. Postal address parsing and normalization. Sub-second. x402-native.

Email verification / validate email: checks if an email address is real and deliverable (SMTP mailbox check), flags disposable, catch-all and role emails. Use before sending, for lead lists, CRM cleanup and sign-up fraud checks. $0.01.

Validates one email (email=) or up to 50 (emails=comma list, same price): RFC 5322 syntax, normalized form, MX records (A fallback), disposable, role account, free provider, typo suggestion, and a deliverable/risky/undeliverable verdict with reasons. No SMTP probing.

B2A Email Deliverability, MX, SPF & DMARC Verifier (/v1/email-verify) — Validates email syntax, disposable/burner provider status, role accounts, and live DNS MX/SPF/DMARC records. (https://email-verify.agentdiet.dev/v1/email-verify)

6 email validation checks in one call — syntax (RFC 5322), MX record verification, disposable detection (5,000+ domains), free provider identification, role-based address detection (admin@, info@), and typo suggestion. Returns a 0-1 confidence score with detailed per-check results. POST method protects email addresses from access logs. No API keys, no multiple service integrations needed. Accepts

Create an email validation job from a JSON list of addresses or CSV text (send exactly one). Poll its status, then fetch results as JSON or CSV. Billing counts only testable addresses, fixed at creation; unreachable, disposable and typo domains are free.

Email validation for signup forms, lead lists and CRM cleanup: checks syntax, MX mail servers, disposable or temporary domains, role addresses (info@, sales@) and free providers. Returns a deliverable_guess. No SMTP probe, no data stored.

Find the cheapest suitable API or software service for an agent task (for example PDF text extraction, web scraping, search, weather, email validation). Returns one recommendation plus alternatives with real prices.

Email validation — Syntax check + live MX/deliverability + disposable-domain flag.

Validate an email address: format check plus a live MX record lookup on its domain

Validate an email address: syntax, MX resolution, disposable-domain check.

Checks one email address and returns valid, risky or invalid with the reasons: address format, whether the domain can receive mail (live MX lookup), known throwaway domains (mailinator and others, invalid), shared inboxes like info@ or sales@ (risky), likely typos such as gmial.com with the fix in didYouMean, and free providers such as gmail.com (flag only). Does not ping the mailbox (no SMTP), so

Pre-payment counterparty risk check for AI agents: OFAC sanctions (names, aliases, wallets), domain age and email authentication, vendor and executive impersonation domains, routing/IBAN/SWIFT/wallet validation, and invoice-fraud signals. Returns proceed/review/block, explained findings and a signed receipt.

Checks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple Mail, and Yahoo. It looks up the BIMI settings the domain has published, checks the logo file follows the required format, checks any logo certificate is valid and unexpired, and confirms the domain has strict enough email protection turned on. Returns a clear pass or fail per domain, plus

Domain and email security check: SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, DNSSEC (validated by Cloudflare and Google), CAA, BIMI with its mark certificate, mail IPs on the UCEPROTECT Level 1 blocklist, TLS certificate, registrar and domain age, and Microsoft 365 tenant, each graded with the exact record to fix it, plus a 0-100 score

Give this tool a list of domain names and it will instantly check each one's DMARC email security record. DMARC is a standard that tells email providers how to handle fake or spoofed emails pretending to come from your domain. For each domain you submit, you get back whether a valid record exists, what the policy is (none, quarantine, or reject), whether reporting addresses are set up, and the ful

Check an email address or domain: MX records, mail provider (Google/Microsoft/Zoho), SPF, DMARC policy, disposable-domain flag and a 0-100 deliverability score. Validate leads before sending.

DNS and list based verification. Never claims that a mailbox exists without evidence: without an SMTP probe the verdict for a routable address is "unknown", not "valid".

For $0.002, privacy-conscious email preflight: submitted addresses and request bodies are not intentionally logged in routine application telemetry (full address still reaches our server). Inspect syntax, DNS/MX, listed disposable domains and provider typos; receive structured decisions. API reverse-proxy access logging is disabled; infrastructure/payment providers may keep records. No zero-retent
