- Buy credits (agent-native crypto): POST https://verifly.email/api/v1/billing {"package_id","method":"crypto","currency":"USDT"} returns a raw wallet address + amount + QR (currencies: BTC, ETH, LTC, USDT, USDC); method "stripe" returns a hosted checkout_url.

## MCP Server And Per-Tool Docs

Verifly is the only email verifier with a hosted MCP server, autonomous agent self-registration, and agent-native crypto pay. The MCP landing page (https://verifly.email/mcp) documents connection (hosted Streamable HTTP endpoint and the verifly-mcp-server npm package) and links every tool. Each of the 15 tools has its own reference page at https://verifly.email/mcp/<tool> with input schema, a tools/call example, the equivalent raw curl, and credit cost.
