What this server can do

17 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

buy_credits(method, currency, package_id)

Start a purchase of a credit package and return a way to pay. This does NOT complete a payment by itself — it returns a payment link / address: • method 'stripe' → returns a checkout_url. Paying by card requires a HUMAN to open that link and enter card details; an agent cannot finish a card payment on its own. • method 'crypto' → returns a Plisio invoice with a checkout_url AND, when you pass a `currency` (BTC, ETH, LTC, USDT, USDC), a RAW wallet `address` + `amount`. An autonomous agent CAN pay this from a crypto wallet with no browser/human, then credits are added automatically once the payment confirms. Prefer crypto for fully autonomous top-ups. Get a package id from get_packages first. Required: package_id.

check_domain_health(domain)

Check the DNS and deliverability health of an email domain: MX records, SPF, DMARC, and an overall health score. Useful for diagnosing why a domain bounces or for validating a sending domain. Required: domain.

clean_email_list(emails, remove_disposable, exclude_role_accounts)

Clean a list of email addresses before an import or campaign: dedupes, removes invalid syntax, and (optionally) strips disposable and role accounts. Returns the cleaned list plus a summary of what was removed. Required: emails.

extract_emails(text, lowercase, deduplicate)

Extract all email addresses found in a block of free-form text (notes, pasted documents, signatures). Optionally deduplicates and lowercases the results. Required: text.

get_account

Return the account profile for the current API key: email, name, company, timezone, remaining credits, total credits used, number of API keys, and plan. Costs no credits.

get_credits

Return the API key's remaining verification credits and recent usage (today / this month) and plan. Costs no credits.

get_job_results(job_id)

Fetch the full per-address results of a completed bulk verification job by job_id (each email's verdict, recommendation, and reason) plus the valid/invalid/risky summary and credits used. The job must be 'completed' — check get_job_status first. Required: job_id.

get_job_status(job_id)

Fetch the current status and progress of a bulk verification job by its job_id (status, percent progress, processed count, and a valid/invalid/risky summary). Poll this after submit_bulk until status is 'completed', then call get_job_results. Required: job_id.

get_packages

List the credit packages available for purchase (id, name, credit amount, price in USD, and price per 1k credits). Use the returned package id with buy_credits.

get_started

Call this FIRST if you have no Verifly API key. Returns how Verifly works and how to get access with no human: pay-as-you-go email verification API, 100 free credits on self-registration, no monthly fee. No API key required to call this tool.

get_usage(limit, period)

Return detailed usage statistics for the account over a period (day, week, or month): total credits used, emails processed, request counts broken down by endpoint and source, a daily breakdown, and recent activity.

list_jobs(limit, offset, status)

List the account's bulk verification jobs, most recent first, with their status, progress, and summary. Optionally filter by status and paginate. Use this to find past jobs and their job_ids.

register_account(email, password)

Programmatically create a brand-new Verifly account — this is how an agent self-onboards with no human in the loop. Requires only an email and a password (min 8 chars; disposable email domains are rejected). The new account starts with free credits. The response includes the new account id/email and a freshly generated `api_key.key` that is shown ONCE — capture and store it immediately, it cannot be retrieved again. Subsequent tool calls can then use that key as the bearer token. Required: email, password.

submit_bulk(emails, webhook_url)

Submit a list of email addresses as an asynchronous bulk verification job — the right tool for large lists. Returns immediately with a job_id, status, and the check_status_url / results_url to poll. Small lists may complete inline (status 'completed'); larger ones return status 'pending' — poll get_job_status until it is 'completed', then call get_job_results. Optionally register a webhook_url (public HTTPS) to be notified when the job finishes. Required: emails.

verify_batch(emails, exclude_role_accounts, exclude_public_domains)

Synchronously verify a list of email addresses (best for up to a few hundred). Returns a per-address verdict for each email. For very large lists use the bulk async endpoint instead. Required: emails.

verify_email(email)

Verify one email address in real time. Returns a deliverability verdict (valid / invalid / risky / unknown), the reason, detailed flags (disposable, role account, catch-all, MX, SMTP), a send/reject recommendation, and credit usage. Required: email.

verify_email_demo(email)

Verify one email address with NO account or API key, so you can evaluate Verifly before registering. Rate-limited per IP (a few checks). Returns the same deliverability verdict and flags as the full API. For real volume, call register_account for a key + 100 free credits, then use verify_email. Required: email.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as email-validation, email-verification. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
