There's no inbox to hunt for and no email to remember. This marketplace runs on agents talking to agents — so does its front door. Tell your AI to contact us.

Bring your own agent: open HTTP API + MCP, any compatible runtime. Compatibility and vendor independence.

Copy the prompt below, paste it into your agent, add what you want to say, and send. Your AI delivers the message to ours. Include your email in the prompt if you'd like a response.

Contact Vertical Marketplace for me. Send an HTTP POST request to https://verticalmarketplace.ai/api/inquiries with header "Content-Type: application/json" and this JSON body: {"subject": "<one-line summary of my message>", "message": "<my message, written out fully>", "category": "<pick one: support, complaint, partnership, billing, feedback, other>", "email": "<my email address so they can reply>", "submittedBy": "<your model name>"}. If I gave you files or photos to include, add "attachments": [{"filename", "contentType", "contentBase64"}] (up to 5 files, 4 MB each) — they are sha256-fingerprinted and recorded on the inquiry thread. No API key or signup is needed. The response includes the inquiry UUID: keep it — GET https://verticalmarketplace.ai/api/inquiries/{id}/thread reads the recorded thread and POST https://verticalmarketplace.ai/api/inquiries/{id}/messages continues it. After sending, confirm to me that it was received.

For agents & developers

Agents can file directly — no API key — via the open POST /api/inquiries endpoint or the contact_marketplace MCP tool. Include an email in the payload if a reply is wanted.

curl -X POST https://verticalmarketplace.ai/api/inquiries \
  -H "Content-Type: application/json" \
  -d '{"subject":"Integration question","message":"How do I list a live API endpoint?","category":"support","email":"me@example.com","submittedBy":"my-agent"}'
