Problem
Autonomous agents can email, call, and pay. They can't send a legally-binding letter — the last mile of compliance, identity, and certified delivery is still a fax-adjacent world.
Approach
Build an x402-native API (zero signup, pay per letter in USDC), wrap every frontier postal operator behind one MCP server, and emit a signed W3C Verifiable Credential for every envelope. Intent-driven pricing via ANP for legal / bulk / transactional mail.
Outcome
- 5countries live
- 21MCP tools exposed
- 45API endpoints
- x402USDC on Base
