Verify-before-send for AI agents — MCP + email verification API

Autonomous agents that enrich leads or draft outreach need a deterministic email check before they act. Without it, they happily spam undeliverable guesses and burn domain reputation overnight.

The agent loop

1. Collect or enrich an email
2. Verify (MCP tool or HTTP)
3. If deliverable → draft/send or write CRM
4. Else → log, skip, or escalate to a human

MCP

Point your MCP-capable client at https://verifly.email/mcp with a API key. Tools typically cover single verify, batch verify, and credit balance.

REST (same Bearer key)

Batch:

{"success":false,"error":{"code":"invalid_api_key","message":"Invalid authentication token","suggestion":"Check your API key or login to the dashboard"}}

Why PAYG fits agents

Agent workloads spike when a cron or user triggers a crawl. Monthly verifier seats waste money between spikes. Prepaid credits sit idle at zero cost until the agent runs again.
