SeqeuenceQ User Guide

This guide is for first-time users. It covers registration, sign-in, wallet top-up, group selection, and API key creation.

Recommended order

Register an account -> sign in -> add funds in Wallet -> confirm the model and group -> create an API key -> send a small test request.

1. Register an account

1. Open the SeqeuenceQ website at https://api.sequenceq.com/.
2. Select the registration entry and complete the username and password fields.
3. Complete email verification or any CAPTCHA, agreement, or privacy-policy step shown by the page.
4. Submit the form and continue to the sign-in page.

Use a long-term email address and a unique password. Do not reuse a password used for payment details or API keys.

2. Sign in

Sign in with the username or email address and password you registered. After signing in, open the dashboard overview at https://api.sequenceq.com/dashboard/overview.

Check the overview page for your balance, usage, and request count.

3. Add funds in Wallet

1. Open Wallet from the left navigation.
2. In Add funds, choose a preset amount or enter a custom amount.
3. Select the available payment method and complete the order.
4. Return to Wallet, refresh the page, and confirm that the balance has updated.

If you have a redemption code, enter it in the redemption-code field and confirm that the available balance or quota changes. For the first test, use a small amount and verify one request before adding more funds.

A balance or available quota is normally required for a paid API request.

4. Choose a group

A group determines which model or service channel an API key can use and may have its own billing multiplier. Before creating a key, open the model list or model marketplace and confirm the target model group.

Typical groups may include:

Group	Typical use
Claude	Claude or Anthropic models
Codex	Codex models
Image	Image-related models
test	Testing only; avoid for production

The groups, models, and multipliers shown in your account are authoritative and may change.

5. Create an API key

1. Open API Keys from the left navigation.
2. Select Create API key.
3. Enter a descriptive name, such as my-app-production or local-test.
4. Select the group you confirmed above.
5. Choose an expiration time. Use a short expiration for temporary tests; use an ongoing key only when you can rotate it regularly.
6. Set the quantity. Keep the default of one unless you need separate keys.
7. Decide whether to enable unlimited quota. Disable it when the key needs its own quota limit.
8. In advanced settings, optionally limit the allowed models or add fixed server egress IPs to the IP allowlist.
9. Select Save changes to create the key.

Copy the complete key immediately after creation and store it in a server-side secret manager or environment variable. Never place it in frontend code, a public repository, screenshots, or chat messages. If you suspect exposure, disable or rotate the key immediately.

6. First request checklist

• Confirm that Wallet shows an available balance or quota.
• Confirm the model name and group match the API key.
• Send a small test request.
• Check the overview, usage dashboard, and request records for the result and cost.
• Create separate keys for testing and production.

Common issues

Can I create a key before adding funds?

The key form may be available before top-up, but a paid request can fail without available balance or quota. Add funds before testing.

Which group should I select?

Select the group shown for the model in the current model marketplace. Use Claude for Claude models, Codex for Codex models, and Image for image models. Keep test for testing only.

The balance did not update.

Confirm that the payment or redemption completed, refresh Wallet, and check the order history. Keep the order information if support is needed.

A request returns 401 or 429.

For 401, check the key, its status, model permissions, and group. For 429, check balance, quota, rate limits, and service status.

The available payment methods, groups, models, multipliers, and page labels may change. Always follow the latest information shown in the SeqeuenceQ console.
