Changelog

What changed, newest first. Only things you can see or call are listed. Dates are production dates.

November 3, 2026: Audit fixes: docs and pricing pages, suggested_action, keyless MCP trial, bulk list cleaner, trust pages

API reference moved to /docs and pricing to /pricing; the home page is shorter.
Every email and phone result carries suggested_action (accept, suggest_correction, review or reject).
MCP tools/call works without a key for a small daily trial per network; validate_emails still needs a key.
Paste or upload a CSV at /clean-list and download the checked list, all in your browser with your own key.
New pages: /about, /changelog, /status, /usage (balance by key) and /chrome-extension-privacy.
POST /v1/account/rotate issues a new secret for the same account.
Frozen widget URL /widget/v1.js with an SRI hash; HEAD requests answered; security headers on every response.
Disposable domain list refreshed from upstream; typo suggestions cover more providers.

/email-validation-regex: 24-address test of popular patterns and what each one misses.
/zerobounce-vs-kickbox-vs-neverbounce: sourced evidence table for a small SaaS.
/catch-all-email: what accept-all domains mean for a pre-send check.
Mobile header hides on scroll down and returns on scroll up.

robots.txt allows AI search crawlers explicitly; API paths stay disallowed.
Append .md to any page URL for a clean Markdown copy; /llms-full.txt bundles the docs.

/email-verification-tools-compared: 47 tools, sortable, with a CSV.
/email-bounce-cost-calculator: what bounces cost and when a list check pays off, formulas shown.

Privacy policy, terms and refund policy published; 14-day refund on unused credits.
/account/delete and DELETE /v1/account remove a key and its data; GET /v1/account/export downloads everything held for a key.
Tables scroll on narrow screens; sitemap carries lastmod.

Checkout idempotency, partial refunds and lost disputes handled in the webhook; HTML error pages; nightly database backups with restore tests.
13 integration guides under /integrations (Next.js, Express, Django, FastAPI, Laravel, Rails, Supabase, Firebase, WordPress, Webflow, Zapier, Make, n8n).
Alternative pages for Bouncer, Hunter, MillionVerifier and DeBounce; disposable-domain pages expanded to 213.
Rate limiter keeps working from memory if the database refuses writes.

POST /v1/email/validate/batch and the validate_emails MCP tool check up to 50 addresses per call, billed per address, all or nothing.
Every non-valid result carries a machine-readable reason; precedence possible_typo, then disposable, then role_address.
Any check whose DNS lookup fails is free, whatever the verdict.
112 typo-domain pages under /email-typo; /.well-known/mcp.json for directories.
Keyless live check on the home page; key page shows a ready-to-run curl.
Widget works with inputs rendered after load (React and site builders) and with a data-selector.

IDN domains, separator-insensitive role detection, did_you_mean typo suggestions, disposable detection through MX hosts, DNS retry and timeout.
Unknown results are not billed.
Sourced comparison table against ZeroBounce, Kickbox, Abstract API and Emailable.
