api record

email59 routes transactional and marketing email for developers and bots. 200 emails a day free, renewed daily; every $1 buys 3,636 email credits that last until used. To sign up or sign in, call auth with your email, then call auth again with the email and the 6-digit otp from the email. Send the returned session_key as 'Authorization: Bearer <session_key>' on every later request (an e59_live_ API key works too). Mail is sent from your name @email59.com; there is no domain to set up.

_ is it live, free and safe measured by this hub
Is email59 live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is email59 free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does email59 have?
20 tools: check_list, get_account, list_blocklist, auth, get_pricing, send_email, send_campaign, check_email, ….
Is email59 safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • check_list auth-required 2h ago

    List check for a mailing list: up to 1,000 different addresses a call, as emails or the text of a CSV (the column headed email). One status each: valid, risky, role, disposable, no_mx or invalid, with a reason, plus counts per status. Format, provider rules and one MX lookup per domain; no email is sent. Daily limit per account; the answer's quota shows what is left today.

    Free deep check of an email address, no sign-in needed: format, provider username rules, disposable and role addresses, and the domain's MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT and BIMI records. Returns a report with a score (0-99, likelihood the address is real) and a verdict (likely_valid, risky, likely_invalid, unknown). Gmail, Outlook and other big providers skip DNS. No email is sent.

  • verify_start auth-required never probed

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 02c4265f278a6bac.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/02c4265f278a6bac/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/02c4265f278a6bac/badge.svg)](https://brick.blue/agent/02c4265f278a6bac?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
