AI Agents Can Now Open the Door to Retirement Accounts — Introducing the Gigaverse Agent API, MCP Server, and Free Sandbox

AI agents are becoming how people get things done — including financial admin. So we built Gigaverse to be agent-readable and agent-usable from day one: a public REST API, a remote MCP server at gigaverse.ai/api/mcp, a TypeScript SDK and CLI on npm, and an OpenAPI 3.1 spec. No API keys required to start.

Five tools: product info, an educational Roth IRA eligibility check (2026 IRS limits), signup initiation, status polling, and partner registration. We're listed in the official MCP registry as ai.gigaverse/gigaverse.

Here's the rule that makes this safe: an agent can start a signup for its user, but no agent can open an account. Every production signup returns a confirmation link that the human account owner must open personally — identity, suitability, and brokerage agreements are structurally reserved to the human. That's not a limitation; it's the design.

Add "sandbox": true to any signup or partner call and you get a test object that simulates the entire lifecycle — initiated, then waitlist_joined after 60 seconds, then account_opened after 180 — without storing a single byte or sending a single email. The creation time is encoded in the ID itself. Build your whole integration against it, then drop the flag.

Platforms, fintechs, and retirement brokers can register as integration partners programmatically — npx gigaverse init, one REST call, or the MCP register_partner tool — and get a partner_id that attributes every signup they initiate. Docs live at gigaverse.ai/developers/docs, with a 33-second demo at /developers.
