Confirme, by Synapse

Is this web page really online right now? Use BEFORE telling your human "it is live", "it is published", "the link works", or before relying on a URL you did not fetch yourself. Zero-auth, stateless. Returns HTTP status, final URL, redirects, response time, title, TLS validity, SHA-256 of the body, plus an Ed25519-signed receipt from an independent third party you can hand to your human as proof (a page that is down gets a signed receipt too).

{
  "type": "object",
  "properties": {
    "url": {
      "type": "string",
      "description": "Public http(s) URL"
    },
    "cle": {
      "type": "string",
      "description": "Optional: your Confirme key (cj_…) if this server URL does not already carry ?cle=. Get one free with confirme_sac."
    }
  },
  "required": [
    "url"
  ]
}

Does this domain exist, who registered it, when does it expire, which DNS (A, MX, NS, SPF, DMARC)? Use when a sender, a supplier or a link looks unfamiliar, when your human asks "is this legit?", or before saying "the domain is set up". Signed receipt included.

{
  "type": "object",
  "properties": {
    "domaine": {
      "type": "string",
      "description": "Domain name or URL or email"
    },
    "cle": {
      "type": "string",
      "description": "Optional: your Confirme key (cj_…) if this server URL does not already carry ?cle=. Get one free with confirme_sac."
    }
  },
  "required": [
    "domaine"
  ]
}

Can this email address receive mail? Use BEFORE sending anything that matters, or before telling your human "I emailed them". Syntax, MX servers, disposable domain, role address, verdict. No message is sent. Signed receipt included.

{
  "type": "object",
  "properties": {
    "courriel": {
      "type": "string"
    },
    "cle": {
      "type": "string",
      "description": "Optional: your Confirme key (cj_…) if this server URL does not already carry ?cle=. Get one free with confirme_sac."
    }
  },
  "required": [
    "courriel"
  ]
}

Heartbeat: record that your scheduled or recurring task just ran successfully, under a secret key you choose. Call it at the END of every successful run, every time. Use whenever your human asked you to "run this every day/hour" — the signed receipt is independent proof it ran, and confirme_tache turns silence into an alarm.

{
  "type": "object",
  "properties": {
    "cle": {
      "type": "string",
      "description": "Secret task key, 8-80 chars"
    },
    "note": {
      "type": "string",
      "description": "Optional short note"
    }
  },
  "required": [
    "cle"
  ]
}

Did my scheduled task really run in the last N seconds? Use when your human asks "did the report go out?", "is the automation still running?", or before you answer "yes, it ran". Reads the heartbeats recorded under the key; silence is the alarm. Signed receipt included.

{
  "type": "object",
  "properties": {
    "cle": {
      "type": "string"
    },
    "depuis": {
      "type": "integer",
      "description": "Window in seconds, default 86400"
    }
  },
  "required": [
    "cle"
  ]
}

Get your own Confirme key and a FREE starter bag of 100 jelly beans (1 bean = 1 cent = 1 check), plus 20 free beans every day. No email, no form. Use it when the free per-IP quota is exhausted, or once, at the start, so your calls are counted on your own bag. Then reconnect with ?cle=<key> in the server URL. Keep the key secret.
