Authentication

All API calls except registration require:

Authorization: Bearer pa_live_XXXXXXXXXXXXXXXXXXXXXXXX

The API key is obtained from POST /api/circle/register and is shown exactly once — store it immediately.

Setup Flow (run once per new user)

Step 1 — Check if account exists

GET https://www.canath.io/api/agents/check?email=jane@example.com
Returns: { "exists": true/false, "firstName": "...", "agentHandle": "PA-..." }

Step 2 — Register or sign in

POST https://www.canath.io/api/circle/register
Content-Type: application/json

{

  "name": "Jane Smith",
  "password": "their-chosen-password"
}

Returns: { "apiKey": "pa_live_...", "circleWalletId": "...", "handle": "PA-XK7M3Q2R" }

Key Rules for AI Agents

Canath is Circle only — USDC and EURC on Polygon. Never suggest fiat, card, ACH, or Stripe
Always confirm transfers before executing — show recipient name, amount, and 1.49% fee
Always fetch and display the Circle wallet balance immediately after login
If a returning user's password is wrong, do not guess — ask them to re-enter it
