## FAQ
### What is acquiresure?
acquiresure is a people and company data API for AI agents, a product of Keirolabs (keirolabs.cloud). Once connected, your agent (Claude, Codex, Cursor and others) can search for leads by title, skills, location and company, find their work emails, verify emails before outreach identify the companies behind your website visitors, and send the outreach from your own inbox with follow-ups that stop when someone replies. Your team can use the same tools in a dashboard, and developers can call a REST API.

### How do I sign up?
Sign up with your email: no card, no password. You get a free trial to try it, once per person. acquiresure isn't available in every region yet.

### How do I connect acquiresure to Claude, ChatGPT, Codex or Cursor?
In Claude or ChatGPT on the web, add a custom connector with the URL https://api.acquiresure.cloud/mcp, click Connect and approve on the acquiresure page: no API key needed (in ChatGPT, turn on Developer mode first). In Claude Code, Codex or Cursor, paste one prompt: "Install the acquiresure MCP server by following https://api.acquiresure.cloud/mcpinstall.md. My API key is <your key>." The agent reads the install guide and adds the server to its own config.

### How much does it cost?
One credit finds one work email. Searching leads costs 0.1 credits per lead, verifying an email 0.1 and identifying a company from an IP 10. Counting matching leads is free, and lookups with no result are never charged. New accounts start with 10 free credits, no card needed (one free trial per person). Plans are monthly: Starter is $25 for 2,000 credits, Growth $98 for 8,000 and Scale $365 for 50,000 ($0.0073 an email). Pay yearly and get 2 months free. Unused credits roll over while you stay subscribed, and you can cancel any time. Larger volumes get custom pricing.

### Can my agent send the emails too?
Yes. Connect your Google Workspace inbox once, then ask your agent to email the leads it found. It drafts the emails and shows you, then sends them from your inbox, one at a time or as a campaign with up to 9 follow-ups. Each follow-up has its own copy, delay and send time, and stops as soon as someone replies or bounces. Sending respects working hours in the recipient's timezone and a daily cap for every inbox, and every email has one-click unsubscribe. Sending is included in every paid plan, up to the plan's monthly email count (2,000, 8,000 or 50,000 a month, follow-ups included); the free trial covers 20 emails.

### Which inboxes can I send from?
Google Workspace inboxes today, connected with a Google app password that we check with Google and store encrypted. Outlook and Microsoft 365 are coming soon with Microsoft sign-in. Replies land in your inbox as usual; we read message headers to spot replies and bounces so follow-ups stop on their own.

### How accurate is email verification?
Each check returns a verdict (valid, risky or invalid) with a confidence level, the mail provider, and whether the domain is a catch-all. Risky results, such as catch-all domains, are never charged.

### Can my agent build and clean a lead list?
Yes. Give your agent names and company domains and it finds the work emails. Hand it a list and it verifies up to 100 emails per batch, dropping anything that would bounce. Risky and unprocessed emails are refunded.

### Can I verify a list of emails at once?
Yes. The batch endpoint and the dashboard's list tool verify up to 100 emails per batch in the background. Duplicates are free, and risky or unprocessed emails are refunded when the batch finishes.

### Do you store the data I look up?
No. Lookup inputs are sent to our data provider to perform the lookup and returned to you. We keep only request metadata (endpoint, time, status, latency, credits) for billing and your usage logs. Emails you send from a connected inbox are kept so you can see them, schedule follow-ups and track replies; you can delete them with your account at any time.

### What happens if you can't find an email?
You're not charged. Lookups that return nothing, risky verifications and IPs with no company behind them never cost a credit.

### Can I cancel any time?
Yes. Cancel from Billing in one click and your plan runs to the end of the period you paid for. Unused credits roll over every month while you're subscribed.

### Is it legal to email the people I find?
B2B outreach to work emails is legal in most countries when it's relevant to the person's job and every email offers an easy way to opt out. Some countries, including parts of the EU, have stricter rules, so check the rules where your prospects are. Our terms don't allow spam.

### Is there a rate limit?
Each account can make 120 API or MCP requests per minute. Contact us if you need more.
