Dexnay for AI agents

Coming soon — endpoints paused

An MCP server and a REST API that let an AI agent swap crypto, manage a wallet, issue and reload prepaid cards, buy gift cards and eSIMs, rent a phone number and send or receive SMS — always inside the spending policy its owner sets. This page documents the interface ahead of launch.

Status

Nothing is live yet. Every MCP call and every API request currently returns:

{
  "status": "coming_soon",
  "message": "This API is not open yet. The documentation is published at /agents; endpoints open later."
}

Connecting (at launch)

MCP endpoint: /mcp on this site (streamable HTTP, JSON-RPC 2.0: initialize, tools/list, tools/call).
REST mirror: /v1/<tool>, one endpoint per tool, JSON in and out.
Authentication: a per-agent API key sent as Authorization: Bearer <key>, created and revoked by the owner.
Each key carries its policy: per-transaction cap, daily cap, allowed assets, merchants and countries, and an approval threshold.

Safety rules built in

Every swap carries a price floor and a refund address: it never executes at an arbitrary price.
Agents never see a recovery phrase or a private key; permissions are scoped and revocable.
Transfers above the policy limit return pending_approval and wait for the owner.
Every call is logged and visible to the owner.
