Verifly

How to start using Verifly (no key needed)

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.

Verify an email — free demo (no key required)

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.

Verify a single email address

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.

Verify a batch of email addresses

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.

Clean an email list

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.

Extract email addresses from text

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

Check email-domain health (MX / SPF / DMARC)

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.

Get remaining Verifly credits

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

Submit an async bulk verification job

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.

Get the status of a bulk verification job

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.

Get the results of a completed bulk job

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.

List bulk verification jobs

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.

Get detailed usage statistics

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.

Get account information

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.

List buyable credit 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.

Buy credits (returns a payment link or crypto invoice)

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

Self-register a new Verifly account + API key

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.
