Recommended Flows

Sign Up

Create a new account via email and OTP

1. Send OTP: POST /api/v1/auth/otp/send with {email, type: "signup"}
2. Verify OTP: POST /api/v1/auth/otp/verify with {email, code, type: "signup"} — returns verification_token
3. Sign up: POST /api/v1/auth/signup with {email, password, verification_token}

Login

Authenticate and receive access/refresh tokens

1. Login: POST /api/v1/auth/login with {email, password} — returns access_token, refresh_token
2. Use access_token as Bearer token in Authorization header for all authenticated requests
3. When access_token expires, refresh: POST /api/v1/auth/refresh with {refresh_token}

Rules

• OTP is required for signup and password reset — always send then verify before proceeding
• Access tokens expire after 1 hour — use refresh_token to get a new one
• After 5 failed login attempts the account is locked — use /auth/unlock to recover
• Never store or log passwords — use them transiently only

Agent Guidance

Follow these instructions when executing this skill:

• Always follow the documented flow order. Do not skip steps.

• If a tool requires authentication, verify the session has a valid bearer token before calling it.

• If a tool requires a transaction PIN, ask the user for it fresh each time. Never cache or log PINs.

• Never expose, log, or persist secrets (passwords, tokens, full card numbers, CVVs).

• If the user requests an operation outside this skill's scope, decline and suggest the appropriate skill.

• If a step fails, check the error and follow the recovery guidance below before retrying.

• To sign up a new user: first call send_otp, then verify_otp, then signup. Never skip OTP verification.

• To reset a password: first call send_otp with type "forget_password", then verify_otp, then reset_password with the verification token.

• All authenticated endpoints require a bearer token obtained from login or login_with_wallet.

• When the access token expires (1 hour TTL), call refresh_token with the refresh token. Do not ask the user to log in again.

• Never log, store, or repeat the user's password back to them.

• If login fails 5 times consecutively, the account locks. To unlock: call send_otp with type "account_unlock", then verify_otp, then unlock_account with the verification token.
