How this service works
Things only humans can do, for AI agents: phone calls, emails and in-person visits, paid per task in USDC via x402. Same-day delivery.
Output
Returns a JSON object confirming the task was accepted, including a unique task_id for tracking, a task_status of ACCEPTED, and an expected_delivery timestamp. The actual email outcome is delivered asynchronously to the provided reply_email or agent_callback_url once a human has completed the task.
Example use cases
Vendor inquiry via human email
“Send an email through Mosbie to procurement@supplierco.com asking if they can provide bulk pricing for orders over 500 units, and send the reply to results@mybusiness.com.”
Appointment confirmation outreach
“Have a human email dr.office@clinicname.com to confirm my appointment is still scheduled for Thursday at 2pm, and post whatever they say back to https://myagent.io/webhook/confirm.”
Freelancer availability check
“Contact freelancer@designstudio.com and ask if they're available to take on a new logo project starting next month — have a real person send the email and report the response to me at hello@mycompany.com.”
Technical details
Endpoint
POSThttps://api.mosbie.com/v1/tasks/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs a real human to send an email — particularly when a human sender is more likely to get a response than an automated system, when the email requires nuanced judgment or natural language that should appear authentically human, or when contacting businesses or individuals who filter or ignore automated outreach. Prefer this over automated email APIs when human credibility and same-day delivery matter.
Side effects
- Missing required fields (objective or recipient_email) returns a validation error
- Invalid or malformed recipient_email causes task rejection
- Neither reply_email nor agent_callback_url provided may cause result delivery failure
- Payment failure via x402 prevents task acceptance
- Recipient does not respond, resulting in no outcome reported back
- Invalid agent_callback_url causes callback delivery failure
