Create your account

Sign up at app.reinx.ai and create your organization. You can explore the dashboard and configure projects, teams, and policies right away — financial operations unlock once identity verification (KYC) completes.
2

Fund your treasury

Add funds from Funding in the dashboard. Bank transfers (ACH/wire) are free; balances are held as USD-pegged stablecoins and displayed in dollars.
3

Create an agent

From the dashboard, create an agent: give it a name, pick a team, set its budget and approval threshold. The agent gets its own non-custodial crypto wallet automatically.When it’s created, copy the agent’s API key — it starts with sk_reinx_live_ and is shown once. This is the only credential your agent needs; it never touches wallet keys.
4

Connect your agent via MCP

Add the Reinx MCP server to your agent’s configuration:
{
  "mcpServers": {
    "reinx": {
      "type": "http",
      "url": "https://mcp.reinx.ai/mcp",
      "headers": {
        "Authorization": "Bearer sk_reinx_live_your_key_here"
      }
    }
  }
}
Or with Claude Code:
claude mcp add --transport http reinx https://mcp.reinx.ai/mcp \
  --header "Authorization: Bearer sk_reinx_live_your_key_here"
5

Make the first payment

Your agent can now check its remaining budget and pay for things — within the rules you set:
// get_budget_utilization — remaining budget (the number that gates payments)
{ "purpose": "Verify available budget before subscribing to data feed" }

// request_wallet_payment
{
  "purpose": "Pay for the market data API subscription",
  "amountCents": 4900,
  "recipient": "0x7a3f...8c21",
  "caip2": "eip155:8453",
  "idempotencyKey": "datafeed-2026-07"
}
Payments at or below your approval threshold auto-approve and execute — unless another policy stage intervenes (an anomaly flag or a project/team approval rule can still route them to review, and hard limits can deny them). Anything above the threshold lands in your Approvals queue — approve or deny from the dashboard (you’ll also be notified by email).
TypeScript and Python SDKs are coming soon. Today, agents connect through the MCP server and humans/automations use the REST API.
